The cluster session-sync filter enable command enables the function for filtering cluster session synchronization information.
The undo cluster session-sync filter enable command disables the function.
By default, the function is disabled.
After a cluster is built, the session backup traffic between member devices is heavy. If the actual link bandwidth is insufficient, the function for filtering session backup information can be used to back up only required sessions, reducing the bandwidth for session backup. Note that after the function for filtering session backup information is configured, services may be temporarily interrupted due to incomplete backup of session entries when a fault occurs.
Precautions
After running the cluster session-sync filter enable command, run the cluster session-sync filter id command to configure filtering conditions.
