Overwrite Control For An Active Zoneset - Cisco MDS 9000 Series Configuration Manual

Configuring and Managing Zones
Step 1
Choose Zone > Edit Local Full Zone Database.
You see the Select VSAN dialog box.
Step 2 Select a VSAN and click OK.
You see the Edit Local Full Zone Database dialog box for the selected VSAN.
Step 3
Click Zones in the left pane. The right pane lists the members for each zone.
Note The default zone members are explicitly listed only when the default zone policy is configured as permit. When
the default zone policy is configured as deny, the members of this zone are not shown. See the
Information, on page
Tip You do not have to issue the copy running-config startup-config command to store the active zoneset.
However, you need to issue the copy running-config startup-config command to explicitly store full zone
sets. If there is more than one switch in a fabric, the copy running-config startup-config fabric command
should be issued. The fabric keyword causes the copy running-config startup-config command to be issued
on all the switches in the fabric, and also saves the full zone information to the startup-config on all the switches
in the fabric. This is important in the event of a switch reload or power cycle.

Overwrite Control for an Active Zoneset

When activating a new zoneset, if users make a mistake while entering the zoneset name, and if this name
already exists on the switch, it results in activation of the wrong zoneset and traffic loss. To avoid activating
a wrong zoneset, the zoneset overwrite-control vsan id command is introduced.
Note
Even when the zoneset overwrite-control vsan id command is enabled, the user can override it and continue
with the activation of a new zoneset using the zoneset activate name zoneset name vsan vsan -id force command.
Step 1 switch# configure terminal
Example:
switch(config)#
Enters configuration mode.
Step 2 switch(config)# zoneset overwrite-control vsan 3
Enables overwrite-control for the specified VSAN.
switch(config)# zoneset overwrite-control vsan 1
WARNING: This will enable Activation Overwrite control. Do you want to continue?
Note The zoneset overwrite-control vsan id command can be enabled only in enhanced zone mode.
Step 3
switch(config)# show zone status vsan 3
