Assigning a Unique Key and Enabling Link Aggregation
Use this command sequence to assign a link aggregation key on ports that do not have link aggregation enabled,
and for all other link aggregation parameters (i.e., system priority, port priority, and link type).
ServerIron(config)# interface ethernet 1/1
ServerIron(config-if-e1000-1/1)# link-aggregate configure key 10000
ServerIron(config-if-e1000-1/1)# link-aggregate active
ServerIron(config)# interface ethernet 1/2
ServerIron(config-if-e1000-1/2)# link-aggregate configure key 10000
ServerIron(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.
NOTE: As shown in this example, when configuring a key, it is pertinent that you assign the key prior to enabling
link aggregation.
The following commands enable passive link aggregation on ports 1/5 – 1/8:
ServerIron(config)# interface ethernet 1/5 to 1/8
ServerIron(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:
ServerIron(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]
See “Link Aggregation Parameters” on page 2-47 for details on the parameters in the command.
Configuring Keys For Ports with Link Aggregation Enabled
NOTE: As shown in this command sequence, to change the key on ports that already have link aggregation
enabled, you must first turn OFF link aggregation, configure the new key, then re-enable link aggregation.
ServerIron(config)# interface ethernet 1/1 to 1/4
ServerIron(config-mif-1/1-1/4)# link-aggregate off
ServerIron(config-mif-1/1-1/4)# link-aggregate configure key 10000
ServerIron(config-mif-1/1-1/4)# link-aggregate active
ServerIron(config-mif-1/1-1/4)# interface ethernet 3/5 to 3/8
ServerIron(config-mif-3/5-3/8)# link-aggregate off
ServerIron(config-mif-3/5-3/8)# link-aggregate configure key 10000
ServerIron(config-mif-3/5-3/8)# link-aggregate active
These commands change the key for ports 1/1 – 1/4 and 3/5 – 3/8 to 10000. Since all ports in an aggregate link
must have the same key, the command in this example enables ports 1/1 – 1/4 and 3/5 – 3/8 to form a multi-slot
aggregate link.
Syntax: [no] link-aggregate active | passive | off
Syntax: [no] link-aggregate configure [system-priority <num>] | [port-priority <num>] | [key <num>] |
[type server | switch]
See “Link Aggregation Parameters” on page 2-47 for details on the parameters in the command.
