Configuring Interop Mode 1
The interop mode1 in Cisco MDS 9000 Family switches can be enabled disruptively or nondisruptively.
To configure interop mode 1 for a VSAN using Fabric Manager, follow these steps:
- Choose VSANxxx > VSAN Attributes from the Logical Domains pane.
- Select Interop-1 from the Interop drop-down menu.
- Click Apply Changes to save this interop mode.
- Expand VSANxxx and then select Domain Manager from the Logical Domains pane.
- Set the Domain ID in the range of 97 (0x61) through 127 (0x7F).
Note This is a limitation imposed by the McData switches.
Note When changing the domain ID, the FC IDs assigned to N ports also change.
- Change the Fibre Channel timers (if they have been changed from the system defaults).
Note The Cisco MDS 9000, Brocade, and McData FC error detect (ED_TOV) and resource allocation (RA_TOV) timers default to the same values. They can be changed if needed. The RA_TOV default is 10 seconds, and the ED_TOV default is 2 seconds. Per the FC-SW2 standard, these values must be the same on each switch within the fabric.
- Optionally, choose VSANxxx > Domain Manager> Configuration tab and select disruptive or nonDisruptive in the Restart column to restart the domain.
Note The Cisco MDS name server shows both local and remote entries, and does not time out the entries.
