Cisco Nexus 2000 Series Fundamental Concepts
Naming Conventions
The naming of interfaces in fabric extender architecture is defined in this document:
There are two types of interface (Figure 21):
●
Host interfaces: The ports connecting to the servers
●
Fabric interfaces: The Cisco Nexus 5000 Series ports connecting to the fabric extender, and the Cisco
Nexus 2000 Series ports connecting to the Cisco Nexus 5000 Series
Figure 21. Fabric Extender Terminology
Management
A fabric extender is not an independent manageable entity; the Cisco Nexus 5000 Series manages the fabric
extender using in-band connectivity. Each fabric extender is identified by a user-specified number in the range 100
through 199. This number is configured by the user from the Cisco Nexus 5000 Series CLI by specifying the
number under the fabric interface links; as a result, the fabric extender connected to these links receives this ID:
nexus5k(config)#interface ethernet 1/1
nexus5k(config-if)#switchport mode fex-fabric
nexus5k(config-if)#fex associate <fex-id>
The fabric extender can be reloaded from the Cisco Nexus 5000 Series CLI:
nexus5k#reload fex <fex-id>
