Chapter 15 Configuring and Managing Zones
Recovering from Link Isolation
Setting Default Zone Policy
Each VSAN contains a default zone, which by default, contains all connected devices assigned to the
VSAN.
You can change the default zone policy for any VSAN by choosing
VSANxxx > Default Zone
from the
Fabric Manager menu tree and clicking the
Policies
tab. However, we recommend that you establish
connectivity among devices by assigning them to a nondefault zone.
The active zone set is shown in italic type. After you have made changes to the active zone set and before
you activate the changes, the zone set is shown in boldface italic type. The tooltip for each zone indicates
the activation time or modification time.
Changing the Default Zone Policy
Each member in the fabric can belong to any zone. If a member does not belong to any zone, it is part
of the default zone. If no zone has been activated in the fabric, all members belong to the default zone.
Even though a member can belong to multiple zones, a member in the default zone cannot be part of any
other zone.
Traffic can be permitted and denied to members in the default zone. This information is not distributed
to all switches. Permission and denial must be set for each switch in the fabric.
To permit or deny traffic to members in the default zone from the Zone Server, follow these steps:
Step 1
Choose
VSANxxx > Default Zone
from the Fabric Manager menu tree, and click the
Policies
tab. The
zone information displays in the Information pane.
Step 2
Click the DefaultZoneBehavior field and choose either
permit
or
deny
from the pull-down menu.
Recovering from Link Isolation
When two switches in a fabric are merged using a TE or E port, these TE and E ports may become
isolated when the active zone set databases are different between the two switches or fabrics. (See
Figure 15-5
.) When a TE port or an E port become isolated, you can recover that port from its isolated
state using one of three options:
•
Import the neighboring switch’s active zone set database and replace the current active zone set. See
“Importing Active Zone Sets” section on page 15-12
.
•
Export the current database to the neighboring switch. See
“Exporting Active Zone Sets” section on
page 15-12
.
•
Manually resolve the conflict by editing the full zone set, activating the corrected zone set, and then
bringing up the link.
