We have a Nexus 5010 (N5K-C5010P-BF version n5000uk188.8.131.52a.N1.1.bin) and are trying unsuccessfully to associate a fabric extender 2148T (N2K-2148T-1GE.
We are using the guide for the 2148T as detailed at the following location;
When trying to configure the 5010 for the interface connected to the 2148T we do not get "fex-fabric" as a configurable option under "switchport"
Switch(config)# int eth 1/17
Switch(config-if)# switchport mode ?
access port mode access
trunk port mode trunk
Switch(config-if)# switchport mode fex-fabric
% invalid command detected at ' ^ ' marker.
Any ideas what we are missing - possible global command to allow fex-fabric to become an option ?
Thanks in advance for any assistance.
