Chapter 11: LACP Port Trunking Commands
168 Section I: Basic Operations
ADD LACP PORT
Syntax
add lacp aggregator= name port= port
Parameters
aggregator Specifies the name of the aggregator. The name is
case-sensitive.
port Specifies the port to be added to the aggregator. You
can add more than one port at a time. You can specify
the ports individually (for example, 5,7,22), as a range
(for example, 18-20), or both (for example, 5,14-16).
Description
This command adds ports to an existing aggregator. You must identify the
aggregator by its name. To display the names of the aggregators on the
switch, refer to “SHOW LACP” on page 179. To create an aggregator,
refer to “CREATE LACP AGGREGATOR” on page 169.
Review the following before adding a port to an aggregator:
ˆ Verify that the port’s speed is set to Auto-Negotiation or 100 Mbps, full-
duplex. Aggregate trunks do not support half-duplex mode.
ˆ The ports of an aggregator must be untagged ports of the same VLAN.
ˆ You cannot add a port to an aggregator that is below the lowest
numbered port in the aggregator, also referred to as the base port. For
example, if an aggregator consists of ports 7 to 12, you cannot add
ports 1 to 6. To change the base port of an aggregator, you must delete
and recreate the aggregator.
Caution
A network cable should not be connected to a port on the switch
until after the port is added to the aggregator. Connecting the cable
before the port is a part of an aggregator can result in loops in your
network topology, which can result in broadcast storms and poor
network performance.
Examples
The following command adds ports 8 and 22 to an aggregator named
“agg_1”:
add lacp aggregator=agg_1 port=8,22
