Configuring Trunk Groups and Dynamic Link Aggregation
As shown in these examples, all or a subset of the ports within a port range will be eligible for formation into an
aggregate link based on port states. Notice that the sets of ports that are eligible for the aggregate link must be
valid static trunk configurations. For example, a 4-port link consisting of ports 1/4 – 1/7 is not valid because this
port configuration is not valid for static trunk groups on the HP device.

By default, link aggregation is disabled on all ports. To enable the feature, use one of the following CLI methods.
USING THE CLI
To enable link aggregation on a set of ports, enter commands such as the following at the interface configuration
level of the CLI.
NO TE: Configuration commands for link aggregation differ depending on whether you are using the default link
aggregation key automatically assigned by the software, or if you are assigning a different, unique key. Follow the
commands below, according to the type of key you are using. For more information about keys, see "Key" on
page 7-30.
Using the Default Key Assigned by the Software
HP9300(config)# interface ethernet 1/1
HP9300(config-if-e1000-1/1)# link-aggregate active
HP9300(config)# interface ethernet 1/2
HP9300(config-if-e1000-1/2)# link-aggregate active
The commands in this example enable the active mode of link aggregation on ports 1/1 and 1/2. The ports can
send and receive LACPDU messages. Note that these ports will use the default key, since one has not been
explicitly configured.
Assigning a Unique Key
HP9300(config)# interface ethernet 1/1
HP9300(config-if-e1000-1/1)# link-aggregate configure key 10000
HP9300(config-if-e1000-1/1)# link-aggregate active
HP9300(config)# interface ethernet 1/2
HP9300(config-if-e1000-1/2)# link-aggregate configure key 10000
HP9300(config-if-e1000-1/2)# link-aggregate active
The commands in this example assign the key 10000 and enable the active mode of link aggregation on ports 1/1
and 1/2. The ports can send and receive LACPDU messages.
NO TE: As shown in this example, when configuring a key, it is pertinent that you assign a key prior to enabling
link aggregation.
The following commands enable passive link aggregation on ports 1/5 – 1/8:
HP9300(config)# interface ethernet 1/5 to 1/8
HP9300(config-mif-1/5-1/8)# link-aggregate passive
The commands in this example enable the passive mode of link aggregation on ports 1/5 – 1/8. These ports wait
for the other end of the link to contact them. After this occurs, the ports can send and receive LACPDU
messages.
To disable link aggregation on a port, enter a command such as the following:
HP9300(config-if-e1000-1/8)# link-aggregate off
Syntax: [no] link-aggregate active | passive | off
Syntax: [no] link-aggregate configure [system-priority <num>] | [port-priority <num>] | [key <num>] |
[type server | switch]
