Configuring LACP
12-7
Setting LACP Partner Key
When you connect the Corecess R1-SW24L2B and other manufacture’s device, you may need to
configure LACP partner key. All LACP ports in an aggregate link have both actor key and
partner key. The Corecess R1-SW24L2B uses these keys internally but some other devices don’t.
These devices can configure an aggregation link only when the partner key of the port on the
device matches the actor key of the port on the other side of the link. To connect the Corecess
R1-SW24L2B and these devises, you should set the partner key.
* Actor key is the operational key value assigned to the port by the Actor.
* Partner key is the operational key value assigned to the port associated with this link by the Partner.
To configure LACP partner key to be assigned to the port on the other side of the aggregation
link, perform this task in the Privileged mode:
Table 12-2 Configuring LACP partner key
Command Task
configure terminal 1. Enter Global configuration mode.
lacp force-partner-key
<key-num>
port <port-type>
<slot>/<port>
2. Configure LACP partner key of the specified port.
y <key-num>: Link aggregation to be assigned (1 ~ 65535).
y <port-type>: The type of the port.
- fastethernet : Fast Ethernet port.
- gigabitethernet : Gigabit Ethernet port.
y <slot>/<port>: The slot number and port number of the port.
end 3. Return to Privileged mode.
show lacp lag all 4. Verify the LACP configuration.
The following example assigns ‘15’ to the port connected to the Fast Ethernet port 2/1 for link
aggregation key:
# configure terminal
(config)# lacp force-partner-key 15 port fastethernet 2/1
(config)# end
# show lacp port fastethernet 2/1
