Port-Channel/LAG (802.3ad) Commands
This section describes the commands you use to configure port-channels, which are also
known as link aggregation groups (LAGs). Link aggregation allows you to combine multiple
full-duplex Ethernet links into a single logical link. Network devices treat the aggregation as if
it were a single link, which increases fault tolerance and provides load sharing. The LAG
feature initially load shares traffic based upon the source and destination MAC address.
Assign the port-channel (LAG) VLAN membership after you create a port-channel. If you do
not assign VLAN membership, the port-channel might become a member of the
management VLAN which can result in learning and switching issues.
