2.12 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.
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.
NOTE: If you configure the maximum number of dynamic port-channels
(LAGs) that your platform supports, additional port-channels that you
configure are automatically static.
2.12.1 port-channel
This command configures a new port-channel (LAG) and generates a logical unit/slot/
port number for 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.
NOTE: Before you include a port in a port-channel, set the port physical
mode. For more information, see 2.1.8 “speed” on page 2 - 4.
Format
port-channel <name>
Mode Global Config
2.12.1.1 no port-channel
This command deletes a port-channel (LAG).
Format no port-channel {<logical unit/slot/port> | all}
Mode Global Config
2.12.2 addport
This command adds one port to the port-channel (LAG). The first interface is a Logical
slot and port number. of a configured port-channel.
NOTE: Before adding a port to a port-channel, set the physical mode of the
port. For more information, see 2.1.8 “speed” on page 2 - 4.
Format addport <logical unit/slot/port>
