Administrators can make simultaneous
configuration changes. Upon activation, one
administrator can overwrite another administrator’s
changes.
Performs all configurations within a
single configuration session. When you
begin a session, the switch locks the
entire fabric to implement the change.
One configuration session for
the entire fabric to ensure
consistency within the fabric.
If a zone is part of multiple zone sets, you create an
instance of this zone in each zone set.
References to the zone are used by the
zone sets as required once you define
the zone.
Reduced payload size as the
zone is referenced. The size
is more pronounced with
bigger databases.
The default zone policy is defined per switch. To
ensure smooth fabric operation, all switches in the
fabric must have the same default zone setting.
Enforces and exchanges the default
zone setting throughout the fabric.
Fabric-wide policy
enforcement reduces
troubleshooting time.
To retrieve the results of the activation on a per
switch basis, the managing switch provides a
combined status about the activation. It does not
identify the failure switch.
Retrieves the activation results and the
nature of the problem from each remote
switch.
Enhanced error reporting
eases the troubleshooting
process.
