IVR Guidelines
Before configuring an IVR SAN fabric, consider the following guidelines:
•
•
•
Note
If you change any FSPF link cost, ensure that the FSPF path distance (that is, the sum of the link costs
Tip
on the path) of any IVR path is less than 30,000.
IVR-enabled VSANs can be configured when the interop mode is enabled (any interop mode) or disabled
Note
(no interop mode).

Domain ID Guidelines

Prior to Cisco MDS SAN-OS Release 2.1(1a), unique domain IDs are required across inter-connected
VSANs. Consider the following guidelines for unique domain IDs:
•
•
Note As of Cisco MDS SAN-OS Release 2.1(1a), unique domain IDs are no longer required.
As of Cisco MDS SAN-OS Release 2.1(1a), in a configuration involving IVR without NAT, if one VSAN
Note
in the IVR topology is configured with static domain IDs, then the other VSANs (edge or transit) in the
topology must be configured with static domain IDs.
Cisco MDS 9000 Family Configuration Guide

Border switch—An IVR-enabled switch that is a member of two or more VSANs, such as the
IVR-enabled switch between VSAN 1 and VSAN 4 in
Edge switch—A switch to which a member of an IVR zone has logged in. Edge switches are
unaware of the IVR configurations in the border switches. Edge switches need not be IVR enabled.
Configure unique domain IDs across all VSANs and switches participating in IVR operations. The
following switches participate in IVR operations:
All edge switches in the edge VSANs (source and destination)
–
– All switches in transit VSANs
Configure IVR only in the relevant border switches.
Acquire a mandatory Enterprise License Package or, as of Cisco MDS SAN-OS Release 2.1(1a), a
SAN Extension over IP License package for this feature.
IVR is bundled with the Cisco MDS 9216i switch and does not require a license.
Minimize the number of switches that require a domain ID assignment. This ensures minimum
traffic disruption.
Minimize the coordination between interconnected VSANs, when configuring the SAN for the first
time, as well as when you add each new switch.
