Syntax Description

on Isolate MLAG ports from sending traffic to local ISC port during link-up transition until remote ISC port is configured.
off Do not isolate MLAG ports from sending traffic to local ISC port during link-up transition.

Default

The default is off.

Usage Guidelines

Under certain circumstances, a temporary (less than a second) loop condition exists when an MLAG port becomes operational, but before the remote MLAG peer installs the ISC blocking filter. MLAG linkup isolation addresses this condition by preventing any flood traffic (broadcast, unknown, unicast, etc.) received on a just operational MLAG port from being forwarded to ISC ports until the remote MLAG peer installs the ISC blocking filter.

Example

The following example enables MLAG linkup isolation:

configure mlag ports link-up-isolation on
