Configuring the Bad Zone Recovery policy (root/config/zone/bzr)
This command displays and configures the bad zone recovery policy for a specific zone.
This policy automatically recovers traffic after a device has brought down the zone. The
switch continuously watches the state of each zone and detects when a failed zone has
not recovered on its own. The switch then bypasses and re-inserts every port within the
zone. However, the Port Test Before Insertion (PTBI) policy does not allow the offending
port to re-insert the zone, which allows all other devices to operate normally.
Note: Bad zone recovery is enabled by default. If bad zone recovery is disabled, use
the following instructions to enable this policy for the appropriate zones.
