N2K Fabric Extender

N2K Fabric Extender Test Procedure
=== Creating a Port Channel === You can create a port channel before you create a channel group.

The software automatically creates the associated channel group.

BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).

SUMMARY STEPS
1. configure terminal

2. interface port-channel 

3. show port-channel summary

4. copy running-config startup-config

Adding a Layer 2 Port to a Port Channel
You can add a Layer 2 port to a new channel group or to a channel group that already contains Layer 2 ports.

The software creates the port channel associated with this channel group if the port channel does not already exist.

BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).

All Layer 2 member ports must run in full-duplex mode and at the same speed.

SUMMARY STEPS
1. configure terminal

2. interface type slot/port

3. switchport

4. channel-group  [ force ] [ mode { on | active | passive }]

5. show interface type slot/port

6. copy running-config startup-config

BEFORE YOU BEGIN
Ensure that you have installed and enabled the Fabric Extender feature set.

switch# configure terminal

switch(config)# interface ethernet 10/1 - 4

switch(config-if)# channel-group 

switch(config-if)# no shutdown

switch(config-if)# exit

switch(config)# interface port-channel 

switch(config-if)# switchport

switch(config-if)# switchport mode fex-fabric

switch(config-if)# fex associate 101

TIP
As a best practice, only enter the fex associate command from the port channel interface, not from the physical interface.

If you try to associate a physical port to a FEX before that physical port is joined to a port channel, the physical port moves to the err-disable state and the Cisco Nexus Series device does not communicate with the FEX on that link.

You must enter the shutdown command and the no shutdown command on the Ethernet interface (not the port channel interface) to clear the err-disable state and bring the link up. (Note that this requirement does not apply if the configuration is performed prior to cabling.)

NOTE
When adding physical interfaces to port channels, all configurations on the port channel and physical interface must match.

This example shows how to display the association of the Fabric Extender and the parent device:

switch# show interface port-channel  fex-intf

Run script 'NEXUS_N2K.py' OR enter these commands from the proper VDC:

sh inv | begin FEX

show fex

show fex  ver

show fex detail

show environment fex 

show int bri

show int fex-fabric

THEN CHECK LOCATOR BEACON LED:
locator-led fex 

no locator-led fex
