vlacp

Configure Virtual Link Aggregation Control Protocol (VLACP) on a port to ensure that there is end-to-end reachability.

Syntax

Command Parameters

enable
Enables VLACP for this port.
ethertype <0X600-0Xffff>
Configures the VLACP protocol identification for this port.
fast-periodic-time <100-20000>
Configures the fast periodic time (in milliseconds) for this port.
flap-frequency <3-30>
Configures the frequency of VLACP flaps allowed in a specific time interval for the VLACP Flap Detect and Damping feature. The default value is 3.
flap-interval <10-600>
Configures the time interval (in seconds) to record the VLACP flaps on ports. The default value is 60 seconds.
funcmac-addr <0x00:0x00:0x00:0x00:0x00:0x00>
Configures the multicast MAC address used for the VLACPDU. Specify a MAC address in the format 0x00:0x00:0x00:0x00:0x00:0x00. The default is 01:80:c2:00:11:00.
slow-periodic-time <10000-30000>
Configures the slow periodic time (in milliseconds) for a specific port type.
timeout {long|short}
Configures the port to use the long or short timeout:

  • Long configures the port to use the timeout-scale value multiplied by the slow-periodic-time.

  • Short configures the port to use the timeout-scale value multiplied by the fast-periodic-time.

For example, if you specify a short timeout, configure the timeout-scale value to 3, and the fast-periodic-time to 400 ms, the timer will expire within 1000 to 1200 ms. To configure this option to the default value, use the default operator with the command.
timeout-scale <2-10>
Configures a timeout scale for this port used to calculate the timeout. The default value is 3. To configure this option to the default value, use the default operator with the command.
