Port-Channel/LAG (802.3ad) Commands
This section describes the commands you use to configure port-channels, which is defined in the 802.3ad
specification, and that 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.
A port-channel (LAG) interface can be either static or dynamic, but not both. All members of a port channel
must participate in the same protocols.) A static port-channel interface does not require a partner system to
be able to aggregate its member ports.
port-channel name
This command configures a name to identify the port channel. The name field is a character string which allows
the dash “-” character as well as alphanumeric characters. Use the
show port-channel command to display the
unit/slot/port number for the logical interface. Instead of unit/slot/port, lag lag-group-id can be used as
an alternate way to specify the LAG interface.
lag lag-group-id can also be used to specify the LAG interface
where
lag-group-id is the LAG port number.
Note: If you configure the maximum number of supported dynamic port-channels (LAGs), additional
port-channels that you configure are automatically static.
Note: Before you include a port in a port-channel, set the port physical mode. For more information,
see “speed” on page 272.
