Zone and Zone Set Issues
Mismatched Default Zone Policy
If you are using basic zoning, you must verify that the default zone policy is the same for all switches in
the VSAN. If the default zone policy varies, then you may experience zoning problems. If all switches
in the VSAN have Cisco SAN-OS Release 2.0(1b) or later, you can use enhanced zoning. Enhanced
zoning synchronizes your zone configuration across all switches in the VSAN, eliminating the
possibility of mismatched default zone policies.
Resolving Mismatched Default Zone Policies Using Fabric Manager
To resolve mismatched default zone policies using Fabric Manager, follow these steps:
Step 1 Choose Fabricxx > VSANxx > zonesetname and select the Policies tab.
Step 2 View the Default Zone Behavior field for each switch in the VSAN to determine which switches have
mismatched default zone policies.
Step 3 Click Apply Changes to save these changes.
Step 4 If you are using basic zoning, Select the same value from the Default Zone Behavior drop-down menu
for each switch in the VSAN to set the same default zone policy.
Step 5 If you are using enhanced zoning, follow these steps:
a. Choose Fabricxx > VSANxx and view the Release field to verify that all switches are capable of
working in the enhanced mode.
All switches must have Cisco MDS SAN-OS Release 2.0(1b) or later. If one or more switches are
not capable of working in enhanced mode, then your request to move to enhanced mode is rejected.
b. Choose Fabricxx > VSANxx > zonesetname and select the Policies tab and set Default Zone
Behavior field to set the default zone policy.
c. Click Apply Changes to save these changes.
d. Select the Enhanced tab and select enhanced from the Action drop-down menu.
e. Click Apply Changes to save these changes.
By doing so, you automatically start a session, acquire a fabric wide lock, distribute the active and
full zoning database using the enhanced zoning data structures, distribute zoning policies, and then
release the lock. All switches in the VSAN then move to the enhanced zoning mode.
Note After moving from basic zoning to enhanced zoning (or vice versa), we recommend that you save the
running configuration.
