z/VM Virtual Networking Link Aggregation - Verify setup
The QUERY PORT command can be used to display information about the
state of the port group from the VM side.
When the VSWITCH is first activated and LACP Active is configured, LACP
negotiations begin with the partner switch. An example of the state
during this transition is:
q port group ethgrp
Group: ETHGRP Active LACP Mode: Active
VSWITCH SYSTEM ETH1 Interval: 300
RDEV: 9C00 VDEV: 9C00 Controller: DTCVSW1
Status: Waiting Reason: LACP negotiation
VSWITCH Connection:
MAC address: 02-22-90-00-00-05
RX Packets: 0 Discarded: 0 Errors: 0
TX Packets: 2 Discarded: 0 Errors: 0
RX Bytes: 0 TX Bytes: 320
Device: 9C02 Unit: 002 Role: DATA Port: 0001 Index: 000
RDEV: 9D00 Controller: NONE
Backup Devices:
RDEV: 2100 Controller: NONE
When LACP negotiations are complete and all devices have been
assigned a controller, QUERY PORT will look similar to this:
q port group ethgrp det
Group: ETHGRP Active LACP Mode: Active
VSWITCH SYSTEM ETH1 Interval: 300

You may also need to verify configuration information from the
partner switch
side. The commands issued depend on the switch you are using.
