Device Alias Distribution
By default, device alias distribution is enabled. The device alias feature uses the coordinated distribution
mechanism to distribute the modifications to all switches in a fabric.
If you have not committed the changes and you enable distribution, then a commit task will fail (see
Example
To enable the device alias distribution, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# device-alias distribute
switch(config)# no device-alias distribute
Legacy Zone Alias Configuration Conversion
You can import legacy zone alias configurations to use this feature without loosing data, if they satisfy
the following restrictions:
•
•
•
If any name conflict exists, the zone aliases are not imported.
Tip
Ensure to copy any required zone aliases to the device alias database as required by your configuration.
When an import operation is complete, the modified alias database is distributed to all other switches in
the physical fabric when you perform the commit operation. At this time if you do not want to distribute
the configuration to other switches in the fabric, you can perform the abort operation and the merge
changes are completely discarded.
To import the zone alias for a specific VSAN, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# device-alias import fcalias

Database Merge Guidelines
Refer to the
OL-6973-03, Cisco MDS SAN-OS Release 2.x
20-10).
Each zone alias has only one member.
The member type is pWWN.
The name and definition of the zone alias should not be the same as any existing device alias name.
