Dynamic link aggregation
Using the default key assigned by the software
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#link-aggregate active
TurboIron(config)#interface ethernet 2
TurboIron(config-if-e10000-2)#link-aggregate active
The commands in this example enable the active mode of link aggregation on ports 1 and 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.
NOTE
In conformance with the 802.3ad specification, the default key assigned to an aggregate link is
based on the port type (1 Gbps port or 10 Gbps port). The device assigns different keys to 10 Gbps
ports than 1 Gbps ports, so that ports with different physical capabilities will not be able to form a
trunk.
Assigning a unique key
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#link-aggregate configure key 10000
TurboIron(config-if-e10000-1)#link-aggregate active
TurboIron(config)#interface ethernet 2
TurboIron(config-if-e10000-2)#link-aggregate configure key 10000
TurboIron(config-if-e10000-2)#link-aggregate active
The commands in this example assign the key 10000 and enable the active mode of link
aggregation on ports 1 and 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 5 – 8.
TurboIron(config)#interface ethernet 5 to 8
TurboIron(config-mif-5-8)#link-aggregate passive
The commands in this example enable the passive mode of link aggregation on ports 5 – 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.
TurboIron(config-if-e10000-8)#link-aggregate
Syntax: [no] link-aggregate
Syntax: [no] link-aggregate configure [system-priority
NOTE
For more information about keys, including details about the syntax shown above, refer to
Dynamic Operation of Allocation Keys
The device dynamically changes a port key based on changes to the port VLAN membership.
