> # 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 zone set 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 zone set database and replace the current active zone set.
> - Export the current database to the neighboring switch.
> - Manually resolve the conflict by editing the full zone set, activating the corrected zone set, and then bringing up the link.
