vpc port channel error

[dave love]

I have two identical switches. One takes the port channel command the other does not. I have tried assigning vlans to it but it doesnt matter. Same with shutting them down first.

N5K9

interface port-channel1
switchport mode trunk
spanning-tree port type network
speed 10000
vpc peer-link

N5K9(config-if)# int e1/4
N5K9(config-if)# channel-group 1
command failed: port not compatible [port mode]

N5K10

interface port-channel1
switchport mode trunk
spanning-tree port type network
speed 10000
vpc peer-link

interface Ethernet1/4
switchport mode trunk
channel-group 1

Try default the interface and add to port-channel, if you got still error

can you port show run interface eth 1/4 and show interface eth 1/4 ourput.

The port is in access mode.  So, change the port to trunk port first and then add it to the PO.

OMG I did that ten times and now it took the command. Bless your talent! However [insert sad emoji]. I  get this weird fabric path error. Everything else works except the 5k vpc peer link.

N5K9(config-if)# sho run int e1/4

interface Ethernet1/4
switchport mode trunk
channel-group 1

N5K9(config)# sh int br

Eth1/4 1 eth trunk down Link not connected 10G(D) 1

N5K9(config)# sh run int po1

interface port-channel1
switchport mode trunk

spanning-tree port type network
speed 10000
vpc peer-link

N5K10(config-if)# sh run int e1/4

interface Ethernet1/4
switchport mode trunk
channel-group 1

N5K10(config)# sh int br
Eth1/4 1 eth trunk down vPC+PeerLnkNotFabricPath 10G(D) 1

So, this "Ethernet1/4 is down (Link not connected)" means the physical link is down. Check to make sure you are using the correct optics on both sides and also using the correct fiber patch cable.

This shows now config is fixed, now goes to testing of Physical cable issue, 

How far distance between these 2 Switches ? suggest to connect to laptop to that port and see if that come up bot the sides.

Check the patch leads, is this single mode or Multi Mode Fibre ?
