a Cisco MDS 9000 switch interface.

Troubleshooting a ZONE Merge Failures

In the example below the show interface command indicates that the E port did not come up due to a
zone merge failure. (Zoning information is on a per VSAN basis. Therefore, for a TE port, it may be
necessary to verify that the zoning information does not conflict for any allowed VSAN.)
switch# show interface fc2/14
fc2/14 is down (Isolation due to zone merge failure)
A E port will segment with (isolation due to zone merge failure) if the following are true.
•
•
To verify the zoning information use the following commands:
switch# show zone vsan 1
switch# show zoneset vsan 1
Two different approaches may be followed to solve a zone merge failure:
•

If the active zonesets on the two switches differ from each other in terms of zone membership
(provided there are zones at either side with identical names )
If the active zoneset on both switches contain a zone with the same name but with different zone
members
.Overwrite the zoning configuration of one switch with the other switch's configuration. This can
be done with the following commands:
switch# zone copy interface fc2/7 import vsan 1
switch# zone copy interface fc2/7 export vsan 1
