Command Function
lacp system-priority
This command configures a port's
LACP system priority.
Use the no form to restore the
default setting.
Syntax:
lacp {actor | partner} system-priority priority
no lacp {actor | partner} system-priority
• actor - The local side an aggregate link.
• partner - The remote side of an aggregate link.
• priority - This priority is used to determine link aggregation group (LAG)
membership, and to identify this device to other switches during LAG
negotiations. (Range: 0-65535)
Default Setting: 32768
Command Mode: Interface Configuration (Ethernet)
Command Usage: Port must be configured with the same system priority
to join the same LAG.
System priority is combined with the switch’s MAC address to form the
LAG identifier. This identifier is used to indicate a specific LAG during
LACP negotiations with other systems.
Once the remote side of a link has been established, LACP operational set-
tings are already in use on that side. Configuring LACP settings for the
partner only applies to its administrative state, not its operational state, and
will only take effect the next time an aggregate link is established with the
partner.
Example:
Console(config)#interface ethernet 1/5
Console(config-if)#lacp actor system-priority 3
Console(config-if)#
lacp admin-key
(Ethernet Interface)
This command configures a port's
LACP administration key.
Use the no form to restore the
default setting.
Syntax:
lacp {actor | partner} admin-key key
[no] lacp {actor | partner} admin-key
• actor - The local side an aggregate link.
• partner - The remote side of an aggregate link.
• key - The port admin key must be set to the same value for ports that
belong to the same link aggregation group (LAG). (Range: 0-65535)
Default Setting: 0
Command Mode: Interface Configuration (Ethernet)
Command Usage: Ports are only allowed to join the same LAG if (1) the
LACP system priority matches, (2) the LACP port admin key matches, and
(3) the LACP port channel key matches (if configured).
If the port channel admin key (lacp admin key - Port Channel) is not set
when a channel group is formed (i.e., it has the null value of 0), this key is
set to the same value as the port admin key (lacp admin key - Ethernet
Interface) used by the interfaces that joined the group.
Once the remote side of a link has been established, LACP operational
settings are already in use on that side. Configuring LACP settings for the
partner only applies to its administrative state, not its operational state, and
will only take effect the next time an aggregate link is established with the
partner.
Example:
Console(config)#interface ethernet 1/5
Console(config-if)#lacp actor admin-key 120
Console(config-if)#
