lacp partner port

[claudiu.jitea]

Hello @All

I was wondering if there is a possibility to find the partner port like it is possible when using pagp (please see below output)

SW-1#sh pagp neighbor  
Flags:  S - Device is sending Slow hello.  C - Device is in Consistent state.
       A - Device is in Auto mode.        P - Device learns on physical port.

Channel group 1 neighbors
         Partner                    Partner                  Partner             Partner    Group
Port      Name                  Device ID                Port         Age   Flags      Cap.
Et0/0     SW-2                 aabb.cc80.0200     Et1/0        6s     SC         10001  
Et0/1     SW-2                 aabb.cc80.0200     Et1/1        2s     SC         10001

thanks and please excuse my newbie question

Hello,

the command 'show lacp neighbor' should work in the same way, provided (obviously) that the port channel is up and active:

S1#sh lacp neighbor
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode

Channel group 1 neighbors

Partner's information:

Hey Georg,

the port information is not from the other switch, that port listing is from the switch you are running the command.

What I was looking was for a command that is showing the partner's ports that are members in the channel.

Hello,

if I change the lacp priority on the neighboring switch, it is reflected in the output, so I think the output is from the neighbor/partner:

S1#sh lacp neighbor detail
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode

Channel group 1 neighbors
