How to view port-channels configured on the controller?


How can we view active port channels on the controller?


We can see the active port channels on a controller with the command below:


(Aruba7210) #show datapath lag

Datapath Trunk (Port-Channel) Table
Port-Channel  Ports   Hash Distribution
------------  ------  -----------------
2             0/0/0   0, 2, 4, 6
              0/0/1   1, 3, 5, 7


We can further view the details as per the command below:


(Aruba7210) (config) #show interface port-channel 2

Port-Channel 2 is administratively up
Hardware is Port-Channel, address is 00:1A:1E:00:44:F0 (bia 00:1A:1E:00:44:F0)
Description: Link Aggregate (LACP)
Spanning Tree is Forwarding
Switchport priority: 0
Member port:
    GE 0/0/0, Admin is up, line protocol is up
    GE 0/0/1, Admin is up, line protocol is up

Port-Channel 2 is NOT TRUSTED


We can see that this port channel is LACP based and it has two interfaces up right now, Ge 0/0/0, GE 0/0/1.


a. If the port channel is LACP based and iit hasn't yet negotiated LACP parameters with the neighbors, it will not be shown above.

b. If the port channel is static and the ports are down, it will not be shown with the command above.
