> # Verifying Interoperating Status

> This section highlights the steps used to verify if the fabric is up and running in interoperability mode.

> Note The Cisco MDS name server shows both local and remote entries, and does not time out the entries.

> To verify the interoperability status of any switch in the Cisco MDS 9000 Family using DCNM for SAN, follow these steps:

> 1. Choose Switches in the Physical Attributes pane and check the release number in the Information pane to verify the Cisco NX-OS release.
> 2. Expand Switches > Interfaces, and then select FC Physical to verify the interface modes for each switch.
> 3. Expand Fabric xx in the Logical Domains pane and then select All VSANs to verify the interop mode for all VSANs.
> 4. Expand Fabric xx > All VSANs and then select Domain Manager to verify the domain IDs, local, and principal sWWNs for all VSANs.
> 5. Using Device Manager, choose FC > Name Server to verify the name server information.

> You see the Name Server dialog box.

> 6. Click Close to close the dialog box.
