Resolving Mismatched Default Zone Policies Using the CLI

To resolve mismatched default zone policies using the CLI, follow these steps:
Step 1 Issue the show zone status command.
v_188# show zone status
VSAN: 1 default-zone: deny distribute: active only Interop: default
Default zone:
Full Zoning Database :
Active Zoning Database :
Status:
This example shows the default zone policy is deny, and the zone mode is basic.
If you are using basic zoning, follow these steps:
Step 2
a.
b.
If you are using enhanced zoning, follow these steps:
Step 3
a.
b.
c.
switch(config)# zone mode enhanced vsan 3000
Note

Zone Merge Failure

A zone merge request may fail because of the following configuration issues:
•
•
OL-9285-05
mode: basic merge-control: allow session: none
hard-zoning: enabled
qos: low broadcast: disabled ronly: disabled
Zonesets:5 Zones:18 Aliases: 11
Name: ZoneSet1 Zonesets:1
Repeat Step 1 for all switches in the VSAN to verify that they have the same zone mode. Use the
zone mode basic command to change any switches that are not in basic mode.
Use the zone default-zone command on each switch in the VSAN to set the same default zone
policy.
Use the show version command on all switches in the VSAN 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.
Use the zone default-zone command to set the default zone policy.
Use the zone mode enhanced vsan-id command to set the operation mode to enhanced zoning
mode.
By doing so, you will 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.
After moving from basic zoning to enhanced zoning (or vice versa), we recommend that you use
the copy running-config startup-config command to save the running configuration.
