Partially meshed NBMA networks typically have multiple logical networks behind the NBMA network. IEEE 802.3af PoE and IEEE 802.3at PoE+ (up to 30W per port) are both supported on Cisco Catalyst 2960-X and 2960-XR Series Switches to lower the total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet wireless access points, or other standards-compliant PoE and PoE+ end devices. There are also a variety of other routing protocols which have been developed, some proprietary and some open. ESXi is the virtualization platform where you create and run virtual machines and virtual appliances. Switch# show mac address-table. Edge and Border - Cat3k Cisco Switch ; Fusion During the step of assigning devices a role of Border Router while adding to the Fabric, a hand-off link can be added. The interface type and number and how long ago it was created (hours:minutes:seconds). The Cisco Catalyst 1000 Series Switches offer a superior CLI for detailed configuration and administration. The supervisor engine sends IP packets that are destined for other IP subnets to the default gateway (typically, a router interface in the same network or subnet as the switch IP address). Cisco Catalyst 1000 Series Switches support both IEEE 802.3af PoE and IEEE 802.3at PoE+ (up to 30W per port) to deliver a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet and Catalyst wireless access points, or other standards-compliant PoE and PoE+ end devices. WebDeployment of the Internet Protocol Version 6 (), the latest generation of the Internet Protocol, has been in progress since the mid-2000s.IPv6 was designed as a replacement for IPv4.IPv4 has been in use since 1982, and is in the final stages of exhausting its unallocated address space, but still carries most Internet traffic.. As of April 2022 Google's statistics Like X.25, Frame Relay is a connection oriented service requiring circuits to be configured by your carrier to establish a physical link between two or more locations. That is, they will share a single IP network number, subnet mask, and broadcast address. It may not reflect the most current legal developments, and Cisco does not represent, warrant, or guarantee that it is complete, accurate, or up to date. Perform this task to change the number of kilobits per second (kbps) at which NHRP sets up or tears down the SVC to this destination. This output shows that Switch 15 is the designated root on the spanning tree for VLAN 1. This policy supersedes any previous warranty or software statement and is subject to change without notice. Note: The wattage rating on the power supply does not represent actual power draw. Flexible payment solutions to help you achieve your objectives. [Set IP address for management] MySwitch(config-if)#exit. After address resolution is complete, router A can send IP packets to router C in one hop, and router C can send them to router E in one hop, as shown by the dotted lines. Virtually all routers support the IP Routing Information Protocol (RIP). Intelligent power management allows flexible power allocation across all ports. Only at that time does NHRP remove the mapping entry. Always at the end of your remember to save your configuration with: To find the current connection lines on your switch. IEEE 802.1X user distribution, which enables you to load-balance users with the same group name across multiple different VLANs. IARP is outlined in RFC 1293. WebCisco Digital Network Architecture (Cisco DNA) provides a roadmap to digitization and a path to realize immediate benefits of network automation, assurance, and security. As your trusted advisor, we help you achieve extraordinary business outcomes, minimize risk and disruption so you can anticipate change and pivot quickly, securely, and confidently. used--Indicates the NHRP mapping was used to forward data packets within the last 60 seconds. Cisco AutoSecure provides a single-line CLI to enable baseline security features (port security, DHCP snooping, Dynamic Address Resolution Protocol [ARP] Inspection). The broadcast address is the address to which devices send packets meant for all other devices. Multilevel security on console access to prevent unauthorized users from altering the switch configuration. Eventually NHRP will time out the current dynamic NHRP mapping entries that it had when the hub went down because they are not being used. The root bridge is selected using settings entered into each bridge (with the Ethernet address acting as a tie-breaker). frame relay switches, routers, access devices, etc.). Port-based ACLs for Layer 2 interfaces to allow security policies to be applied on individual switch ports. NHRP Resolution. Enables IP and gives the interface an IP address. In fact, if configured, the tunnel destination must correspond to an IP multicast address. Laptops and tablets can access the switch CLI using a Telnet or Secure Shell (SSH) client over Bluetooth. This could be the department the devices are used in, the physical location of the devices, or some other method of categorization. Clears the IP NHRP cache of dynamic entries. Configuring Basic Switch Management Access with IPv4 (2.1.1.5) Perform this task to specify the authentication string for NHRP on an interface. This method consists of SVCs being initiated based on the input traffic rate to a given BGP next hop. Displays the current configuration. Global DLCI addressing is a Local Management Interface (LMI) extension that allows a DLCI number to have universal significance. Perform this task to specify which interface the Next Hop Server uses for the NHRP responder IP address. Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. To configure multiple networks that the Next Hop Server serves, repeat the, To configure additional Next Hop Servers, repeat the. This is acceptable as long as all seed routers on the segment are seeding the same network number. Local DLCI addressing means that DLCI numbers are only significant at one end of a Frame Relay virtual circuit (VC). The corresponding crypto map entry is deleted. It indicates the maximum power draw possible by the power supply. Using a dynamic-mesh network allows smaller spoke routers to participate up to their capability in a large NBMA network when these smaller spoke routers do not have the resources to participate in a full mesh on the same size network. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module. A non-extended network can only have one zone (which will also be the "default zone" for the segment). SVCs are analogous to X.25 connections, which require call setup and tear down. When using NHRP in distributed CEF switching mode, this value must be set to 5 seconds. For example, GRE uses a network service access point (NSAP) address, Ethernet uses a MAC address, and SMDS uses an E.164 address. The larger the max-send interval the more NHRP packets the system can process and send. IGMP snooping for IPv4 and IPv6 and Multicast Listener Discovery (MLD) v1 and v2 snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requesters. With NHRP, systems attached to an NBMA network can dynamically learn the NBMA (physical) address of the other systems that are part of that network, allowing these systems to directly communicate. An autoseeding default router configuration simplifies administration of routers since AppleTalk can be routed right out of the box without any additional configuration. WebOpen Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. The DMVPN feature allows users to better scale large and small IP Security (IPsec) Virtual Private Networks (VPNs) by combining generic routing encapsulation (GRE) tunnels, IPsec encryption, and Next Hop Resolution Protocol (NHRP). Learn more. You can change the length of time over which the average trigger rate or teardown rate is calculated. The significant portions of the configurations for routers A and B follow: The following is sample output from the show ip nhrp command: The fields in the sample display are as follows: The following example shows output for a specific tunnel, tunnel7: Router# show ip nhrp traffic interface tunnel0. MAC address notification to notify administrators about users added to or removed from the network.

QoS through Differentiated Services Code Point (DSCP) mapping and filtering. Purge Request--Number of NHRP reply packets received by this station. 4. ip nhrp nhs nhs-address [net-address [netmask]]. Access Control Lists (ACLS) for IPv6 and IPv4 security and Quality-of-Service (QoS) ACL elements (ACEs). This process would increase the utilization of the hubs physical bandwidth and CPU to process these packets that enter and exit the hub on the multipoint interface. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. The algorithm calculates the best loop-free path through a switched Layer 2 network by assigning a role to each port based on the role of the port in the active topology: a manually entered unicast address that does not age and that is not lost when the switch resets. 198.41.12.151, 255.255.255.0, and 198.41.12.255). Warranty allows guest access only to Cisco.com. Cloud-based and artificial intelligence (AI)-powered ITSM platform offering employee service management and IT asset management (ITAM) capabilitiesincluding asset discovery and incident, problem, release, and change managementsupported by a configuration management database (CMDB) and built to integrate with the authoritative--Indicates that the NHRP information was obtained from the Next Hop Server or router that maintains the NBMA-to-IP address mapping for a particular destination. WebDownload this Cisco Switch Commands Cheat Sheet as PDF file to have it as reference with you in the field. This section describes the mechanism to refresh the spoke-to-spoke tunnel when it is still being used (no packet loss) and to detect and remove the spoke-to-spoke tunnel when it is no longer being used. It is more flexible and easier to configure than static configuration. Frame Relay is a streamlined subset of the X.25 packet switching protocol which has been used by many corporations for wide area communications for a number of years. Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports. The dynamic-mesh network allows individual spoke routers to directly connect to anywhere in the NBMA network, even though they are capable of connecting only to a limited number at the same time. To determine a network number to use for autoseeding, a router listens to the network for several RTMP periods, and then examines its routing table (which is filled in with information from RTMP packets), and picks an unused number for each interface. Fortunately for workstation users, the NetWare client software does the work of discovering the network number and setting the address. Fast ethernet models provide reduced functionality and scalability compared to the Gigabit ethernet models and are targeted for deployments with basic requirements. FigureA-2 shows an example of Appletalk routing. Devices whose services match the information in the lookup will respond to it, and the response will be forwarded back to the original machine. Forward and Reverse Record information is required for the proper operation of NHRP, especially in a DMVPN network. All routers configured with NHRP within one logical NBMA network must share the same authentication string. DHCP auto configuration of multiple switches through a boot server eases switch deployment. Similarly, SVCs can be torn down when traffic falls to another configured rate. SVCs are generally not yet available from Frame Relay carriers. Each device on an IP network requires 3 different pieces of information in order to correctly communicate with other devices on the network: an IP address, a subnet mask, and a broadcast address. IP communications between these two segments will be bridged, not routed. C1000-24FP-4G-L, C1000-24FP-4X-L 34.8 dB, Note: Bystander positions operating mode at 77F (25C) ambient; All other models are fanless for silent operations, UL 60950-1 Second Edition, CAN/CSA-C22.2 No. The generic advantage provided by Frame Relay is its ability to combine multiple streams of "bursty" data (such as LAN protocol traffic) all of which have relatively low average usage rates, into a single channel with a relatively higher average usage rate. Performing this procedure incorrectly can lead to data loss. Displays the IP NHRP cache, which can be limited to dynamic or static cache entries for a specific interface. But not all IP addresses can be reached through the public internet, and 192.168.1.1 is among them. To remove an IP address from an SVI, use the no ip address interface configuration command. A simplified bridging table is shown below: When a packet with A as a destination address arrives at Port 0, the packet is dropped (A is on the same interface). If one user subscribed to Group A (as designated by 224.1.1.1) and the other users subscribed to Group B (as designated by 225.1.1.1), they would both receive both A and Flexible mechanisms for marking, classifying, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Refer again to the first figure above. WebSystem Manager is a simple and versatile product that enables you to easily configure and manage ONTAP clusters. When router A first forwards the IP packet toward the destination host, router A also generates an NHRP request for the IP address of the destination host. For this reason, the default configuration for routers which support IPX has both 802.3 Raw and 802.2 set to autoseed (they will come up regardless of whether there is a server on line or not) and the other two frame types set to non-seed (they won't come up unless they "hear" another router using this frame type. In the event of discontinuance of product manufacture, Cisco warranty support is limited to 5 years from the announcement of discontinuance. Switch# show run. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. These are simple, flexible and secure switches ideal for out-of-the-wiring-closet and critical Internet of Things (IoT) deployments. If you are subnetting, use TableA-3 as a guide for Class C, or follow the same scheme for Class A or B. WebVirtual Routing and Forwarding or VRF is a technology that supports multiple routing instance inside a single router (or layer-3 switch). The algorithm relies on the use of Bridge Protocol Data Units (BPDU packets), which provide information to all bridges about the "distance" in hops to each bridge interface from a "root bridge." Perform this task to change the sampling time period and the sampling rate. If an NHRP reply packet being forwarded by a Next Hop Server contains the IP address of that server, the Next Hop Server generates an error indication of type NHRP Loop Detected and discards the reply. Switch-port auto-recovery (error disable) automatically attempts to reactivate a link that is disabled because of a network error. When the NHRP mapping entry expires and if it is the last mapping entry with this NBMA address, then the ISAKMP peer also performs items 1 through 5. vCenter Server is the service through which you manage multiple hosts connected in a network and pool host resources.. Want to know what is in the current release of This would cover spoke-to-spoke tunnel creation and the refreshing of spoke-to-spoke tunnels that are used for longer periods of time. FigureA-4 shows a four interface router which also supports bridging. Dynamic VLAN facilitates the fast assignment of IP addresses. For more in-depth information, the definitive reference is Gursharan Sidhu et al's Inside AppleTalk (Addison-Wesley Publishing). Cisco Auto SmartPorts enables automatic configuration of switch ports as devices connect to the switch with settings optimized for the device type, resulting in zero-touch port-policy provisioning. For more information about Cisco Catalyst SmartOperations, visit cisco.com/go/SmartOperations. The documentation set for this product strives to use bias-free language. Learn more about how Cisco is using Inclusive Language. IARP is used when a router discovers a new PVC with its corresponding DLCI on a physical interface. Each physical network segment is assigned a network number by the routers on the segment. The MAC address of the designated root switch, 00-10-0d-b1-78-00, is the same as the bridge ID MAC address of Switch 15, 00-10-0d-b1-78-00. It operates according to the following rules: 1. The NHS is declared down if an NHRP registration reply is not received after three retransmission (7 seconds), and an NHRP resolution packets will no longer be sent to or by way of that NHS. At layer 2 it is a trunk link connected to the Fusion Router. Ability to disable per-VLAN MAC learning to allow you to manage the available MAC address table space by controlling which interface or VLANs learn MAC addresses. If the expire time is >120 seconds and the used flag is set, then the used flag is cleared. Following steps are needed: ip address 172.16.10.1 255.255.255.255 end Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting. Tables 6 and 7 list ordering information for the Cisco Catalyst 1000 Series Switches. Because bridges maintain very little information about network topology, they are easier to configure than routers. The fields shown in the sample display are as follows: The following sections provide references related to configuring NHRP. The software features supported on the Cisco Catalyst 1000 Series can be found on Cisco Feature Navigator: https://cfn.cloudapps.cisco.com/ITDIT/CFN/jsp/by-feature-technology.jsp. Log in to the switch. Actual delivery times might vary depending on customer location. It may sometimes be desirable for redundancy to have several seed routers on a segment. 6. show ip nhrp [dynamic | static] [type number]. This support does not include solution or network-level support beyond the specific device under consideration. Once a device has successfully claimed an address, it contacts a router on its segment and asks for a list of zones for the segment. Assigning a cost to a neighbor is optional. This command is required on multipoint GRE tunnels and not required on point-point RE tunnels. This value is based on the. In more than 100 countries, our flexible payment solutions can help you acquire hardware, software, services and complementary third-party equipment in easy, predictable payments. Switch(config)# interface vlan 33 Switch(config-if)# ip address This capability effectively creates a full-mesh-capable network without having to discover all possible connections beforehand. 5. ip nhrp registration timeout seconds. How much of any given address is the network part and how much is the host part is determined by the "class" of the network. Cisco switch interface example config . Specifies an IP access list that controls NHRP requests. The switch can route traffic between VLANs by using switch virtual interfaces (SVIs). Then when the NHRP background process runs (every 60 seconds) the following actions occur: NHRP has no knowledge about when a packet is Cisco Express Forwarding (CEF) switched through the spoke-to-spoke tunnel. In this example, the triggering and teardown thresholds are calculated based on an average over 120 seconds. Therefore, if the authentication scheme is to be used, the same string must be configured in all devices configured for NHRP on a fabric. In this example, ten NHRP packets can be sent from the interface every 10 seconds (twice the default rate). The IPX Bridge Group consists of Port 1 and Port 2. It will not work correctly if there are multiple paths to the same destination. WebThis is not an official Cisco document, and as such, this information is provided "as-is." A global DLCI identifies the same VC at both ends. Establishing the network number for an IPX network segment is referred to as "seeding" the network. These switches deliver enhanced network security, network reliability, and operational efficiency for small organizations. Learn how to Configure a Cisco Switch. An extended network can have from 1 to 255 zones, one of which will be the default zone. Cisco or its service center will use commercially reasonable efforts to ship a Cisco Catalyst 1000 Series replacement part for next-business-day delivery, where available. It also has an intuitive dashboard for configuring, monitoring, and troubleshooting the switch (Figure 1). The address of an individual device on the segment consisted of the network number, along with an 8 bit node address value. 4. ip nhrp map ip-address nbma-address, 5. ip nhrp map multicast nbma-address. By removing a number of the X.25 protocol's seldom-used functions and their associated overhead, the Frame Relay protocol allows communications at up to T1 speeds (about 1.5 megabits per second). In particular, Rick Sant'Angelo's NetWare Unleashed (SAMS Publishing) provides a good overview of IPX routing along with tips on getting IPX drivers correctly loaded on client machines. Step 1. c. Shows all interfaces, their In this case, NHRP does not store mapping information in the NHRP cache, such as NHRP responses that go through the router. NHRP registrations are sent from NHCs to their configured NHSs every one-third of the NHRP holdtime (configured by the ip nhrp holdtime value command), unless the ip nhrp registration timeout value command is configured, in which case registrations are sent out according to the configured timeout value. In contrast to routers, bridges operate on the "physical" network layer. When a router has multiple interfaces, and also supports bridging/switching, some new concepts are required to understand the organization of the available functions. Information about Ciscos environmental sustainability policies and initiatives for our products, solutions, operations, and extended operations or supply chain is provided in the Environment Sustainability section of Ciscos Corporate Social Responsibility (CSR) Report. Table 5 describes the available accessories. It's intended to help our customers who may have a situation where they need to reset the password on their Cisco Catalyst switch. In general, all NHRP stations within a logical NBMA network should be configured with the same network identifier. By default, all non-NHRP packets trigger NHRP resolution requests. Packets which must go between devices belonging to two different groups travel through routers, which forward them along an optimal path. Only Phase 2 extended networking is turned on in the default configuration, with network ranges of 1. These mapping entries are not used to forward data packets. NHRP resolution requests traverse one or more hops (hubs) within the base hub-and-spoke NBMA subnetwork before reaching the station that is expected to generate a response. When there is only one hub and that hub goes down, the spoke removes the routes that it learned from the hub from its routing table, because it lost the hub as its routing neighbor. An NHS normally uses the network layer forwarding table to determine where to forward NHRP packets and to find the egress point from an NBMA network. The PVC is discovered by communicating with the Frame Relay switch using the LMI protocol. The address format is appropriate for the type of network being used (for example, GRE, Ethernet, SMDS, or multipoint tunnel. SPAN, with bidirectional data support, to allow the Cisco Intrusion Detection System (IDS) to take action when an intruder is detected. Otherwise, a replacement will be shipped within 10 working days after the receipt of the RMA request. 4. ip nhrp trigger-svc trigger-threshold teardown-threshold. A PVC on one router is directly connected to a PVC on another router. Similarly, router C generates an NHRP request of its own, to which router E replies. One of the disadvantages to this technique is that each spoke must have all of the individual routes in its routing table for all possible destination networks behind the hub and other spokes. If you wish to compute it yourself, use the examples in TableA-4 above as a guide. In phase 2, NHRP brings up the NHC-to-NHS tunnel and a dynamic routing protocol is used to distribute routing information about all of the networks that are available behind the hub and all of the other spokes. Configures an interface and enters interface configuration mode. We recommend that the same NHRP network ID be used on the GRE interfaces on all routers that are in the same NHRP network. This design ensures that connectivity is always preserved, even when the preferred single hop path is not available. If no match is found, or if the destination address is the broadcast address, forward the packet out all active interfaces. This is a very brief introduction to the concept of bridging networks. TableA-3 shows all of the possible Class C subnet masks, and how many hosts are then allowed on each subnet. The network number can be in the range of 1 to FFFFFFFE (that's 8 hexadecimal digits). Spanning Tree Root Guard (STRG) to prevent edge devices that are not in the network administrators control from becoming Spanning Tree Protocol (STP) root nodes. Once configured, issue the show running-config again to verify your configuration. Cisco Catalyst 1000 Series Switches offer a range of industry-leading features for energy efficiency and management: IEEE 802.3az Energy Efficient Ethernet (EEE) enables ports to dynamically sense idle periods between traffic bursts and quickly switch the interfaces into a low-power idle mode, reducing power consumption. When an NHRP reply is received, a subsequent route is put in the NHRP cache that directly corresponds to the BGP next hop. (Optional) Adds an NBMA address to receive multicast or broadcast packets sent out the interface. You can also create standard ACLs with the following set of commands. The figure below illustrates four routers connected to an NBMA network. Users only need to install Novell drivers to be able to use the IPX protocols over their network. In particular, Douglas Comer's Internetworking with TCP/IP (Prentice Hall) is one of the standard references and provides a wealth of information on the subject.

Line 5 shows what happens when a Class C network has been subnetted. VLANs are identified by a number from 1 to 4094. Traffic Indication--Number of NHRP traffic indication packets (redirects) originated or received from this station. WebSystem Manager is a simple and versatile product that enables you to easily configure and manage ONTAP clusters. 1-30, 33-62, 65-94, 97-126, 129-158, 161-190, 193-222, 225-254, 1-14, 17-30, 33-46, 49-62, 65-78, 81-94, 97-110, 113-126, 129-142, 145-158, 161-174, 177-190, 193-206, 209-222, 225-238, 241-254. In this example, the segment connected to Port 3 has its own IP network number, subnet mask, and broadcast address. This responding station either serves the destination, or is the destination itself. In this example, NHRP NBMA addresses are advertised as valid in positive NHRP responses for 10 minutes. Select the Static IP Address radio button. Among routable network protocols, IPX is relatively simple. As NHRP packets arrive on a GRE interface, they are assigned to the local NHRP domain in the NHRP network ID that is configured on that interface. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Bluetooth for over-the-air access. NHRP is an ARP-like protocol that alleviates these NBMA network problems. A logical group will typically consist of all of the machines on a physical network segment (such as an Ethernet segment). It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).. OSPF gathers link state information from available routers and constructs a topology map of the network. You should generally only have one seed router per network cable segment. nat--Indicates an NHRP mapping entry for which IPsec socket (for encryption) has not been triggered. Included in this information is the IP next hop of the destination spoke that is supporting a particular destination network. FigureA-5 shows three remote office 56K Frame Relay connections feeding one central office T1 connection. When the NHRP background process runs, the following actions occur: In both the process and CEF switching cases, refreshed means that another NHRP resolution request is sent and response is needed to keep the entry from expiring. The switch supports VLANs in VTP client, server, and transparent modes. With NHRP, systems attached to an NBMA network dynamically learn the NBMA address of the other systems that are part of that network, allowing these systems to directly communicate without requiring traffic to use an intermediate hop. Cisco Catalyst 1000 Series Switches include a single fixed power supply. FigureA-1 shows an example of IPX routing. This example shows how to configure a Layer 3 SVI and to assign it an IP address: Switch# configure terminal Enter configuration commands, one per line. Your formal warranty statement, including the warranty applicable to Cisco software, appears in the information packet that accompanies your Cisco product. NHRP resolution requests are used to build direct paths between two NHRP nodes. In such configurations, packets traversing the NBMA network might have to make several hops over the NBMA network before arriving at the exit router (the router nearest the destination network). Registration Request--Number of NHRP resolution reply packets originated from or received by this station. Connect the switchs power cable to the power source, and wait for the lights to come up. Router C can also communicate with routers D and E because they share network identifier 7. It may sometimes be desirable for redundancy to have several seed routers on a segment. Learn more about how Cisco is using Inclusive Language. Dynamic VLAN assignment through implementation of VLAN Membership Policy Server client capability to provide flexibility in assigning ports to VLANs. We recommend that a value from 300 to 600 seconds be used. But for this same reason, they do not limit traffic on network segments as well as routers do, and they are more prone to propagating network problems from one segment to another. Enter the following command to assign a hostname: (Change the IP address): Switch# destination 117.156.45.241; The campus local area network (LAN) is the network that supports devices people use within a location to connect to information. CEF switching or distributed CEF (dCEF) switching must be enabled. NHRP allows two functions to help support these NBMA networks: With NHRP, the NBMA network is initially laid out as a hub-and-spoke network that can be multiple hierarchical layers of NHCs as spokes and NHSs as hubs.
