Configures MLAG (Multi-switch Link Aggregation Group) linkup isolation, which prevents flood traffic received on newly operational MLAG ports from being forwarded to ISC ports before the ISC blocking filter is installed.
| 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. |
The default is off.
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.
The following example enables MLAG linkup isolation:
configure mlag ports link-up-isolation on
