Command Function
lacp admin-key
(Port Channel)
This command configures a port
channel's LACP administration
key string.
Use the no form to restore the
default setting.
Syntax:
lacp {actor | partner} admin-key key
[no] lacp {actor | partner} admin-key
• key - The port channel admin key is used to identify a specific link
aggregation group (LAG) during local LACP setup on this switch.
(Range: 0-65535)
Default Setting: 0
Command Mode: Interface Configuration (Port Channel)
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.
Note that when the LAG is no longer used, the port channel admin key is
reset to 0.
Example:
Console(config)#interface port-channel 1
Console(config-if)#lacp actor admin-key 3
Console(config-if)#
lacp port-priority
This command configures LACP
port priority.
Use the no form to restore the
default setting.
Syntax:
lacp {actor | partner} port-priority priority
no lacp {actor | partner} port-priority
• actor - The local side an aggregate link.
• partner - The remote side of an aggregate link.
• priority - LACP port priority is used to select a backup link.
(Range: 0-65535)
Default Setting: 32768
Command Mode: Interface Configuration (Ethernet)
Command Usage: Setting a lower value indicates a higher effective
priority.
If an active port link goes down, the backup port with the highest priority is
selected to replace the downed link. However, if two or more ports have the
same LACP port priority, the port with the lowest physical port number will
be selected as the backup port.
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 port-priority 128
