Chapter 11: LACP Port Trunking Commands
176 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(s) to be added to the aggregator. Port
numbers are specified in the following format:
module ID.port number
For instructions, refer to “Port Numbers in Commands”
on page 42.
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 188. To create an aggregator,
refer to “CREATE LACP AGGREGATOR” on page 178.
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 could result in loops in your
network topology, which can cause broadcast storms and poor
network performance.
