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 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 system-priority 3
Console(config-if)#
