Removing Ports from Aggregators

748
To remove ports from an aggregator, use the NO CHANNEL-GROUP
command, in the Port Interface mode. Move to the Port Interface mode for
those ports you want to remove from an aggregator and enter the
command. You can remove ports from only one aggregator at a time.
Caution
Do not remove a port from an aggregator without first disconnecting
the network cable. Leaving the network cable connected may result
in a network loop, which can cause a broadcast storm.
Note
You cannot remove the base port of an aggregator. The base port is
the lowest-numbered port of an aggregator. For example, you
cannot delete port 7 from an aggregator consisting of ports 7 to 12.
Removing the base port requires deleting and recreating the
aggregator to which the base port belongs.
These commands delete ports 11 and 12 from an aggregator:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.11-port1.0.12
awplus(config-if)# no channel-group
