About Recovering from Link Isolation

When two switches in a fabric are merged using a TE or E port, these TE and E ports may become isolated
when the active zoneset databases are different between the two switches or fabrics. When a TE port or an E
port become isolated, you can recover that port from its isolated state using one of three options:
• Import the neighboring switch's active zoneset database and replace the current active zoneset (see
• Export the current database to the neighboring switch.
• Manually resolve the conflict by editing the full zoneset, activating the corrected zoneset, and then

Importing and Exporting Zone Sets

Note
Issue the import and export commands from a single switch. Importing from one switch and exporting from
another switch can lead to isolation again.
To import or export the zoneset information from or to an adjacent switch, follow these steps:
Step 1
switch# zoneset import interface fc1/3 vsan 2
Imports the zoneset from the adjacent switch connected through the fc 1/3 interface for VSAN 2.
Step 2
switch# zoneset import interface fc1/3 vsan 2-5
Imports the zoneset from the adjacent switch connected through the fc 1/3 interface for VSANs ranging from 2 through
5.
Step 3
switch# zoneset export vsan 5
