Configure Global LACP Parameters

Configure LACP parameters globally. After you configure the LACP system priority globally, it applies to all LACP-enabled aggregators and ports. After you enable the LACP on an aggregator or a port, it uses the global system priority value.

A change to the global parameter configuration takes effect after you restart the LACP globally or on each port.

About this task

Important

Changes made at the global level override and reset all port level settings.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Change the system priority:

lacp system-priority <0-65535>
Configure additional LACP parameters as required:

lacp enable [aggr-wait-time <200-2000>] [fast-periodic-time <200-20000>] [slow-periodic-time <10000-30000>] [smlt-sys-id <0x00:0x00:0x00:0x00:0x00:0x00> ] [system-priority <0–65535> ] [timeout—scale <2–10>]

If you do not configure the optional parameters, the system uses the default values.

Example

Switch:1(config)#lacp fast-periodic-time 2000
Switch:1(config)#lacp enable

Variable Definitions

The following table defines parameters for the lacp command.


Variable	Value
aggr-wait-time `<200–2000>`	Configures the aggregation wait time (in milliseconds) globally. The default value is 2000.
enable	Enables LACP globally. The default value is disabled.
fast-periodic-time `<200–20000>`	Configures the fast periodic time (in milliseconds) globally. The default value is 1000.
slow-periodic-time `<10000–30000>`	Configures the slow periodic time globally. The default value is 30000.
smlt-sys-id `<0x00:0x00:0x00:0x00:0x00:0x00>`	Configures the LACP system ID globally. Enter a MAC address in the following format: 0x00:0x00:0x00:0x00:0x00:0x00.
system-priority `<0-65535>`	Configures the LACP system priority globally. The default value is 32768.
timeout-scale `<2-10>`	Configures the timeout scale globally. The default value is 3.
