Configuring IVR
To configure IVR in a SAN fabric, follow these steps.
Verify that unique domain IDs are configured in all switches and VSANs participating in IVR.
Step 1
Enable IVR in the border switches.
Step 2
Create and activate the required IVR topology in all the IVR-enabled border switches.
Step 3
Create and activate IVZSs in all the IVR-enabled border switches.
Step 4
Step 5
Verify the IVR configuration.
Unique Domain ID Configuration Options
You can configure domain IDs using one of two options:
•
•
Enabling IVR
The IVR feature must be enabled in all border switches in the fabric that participate in the IVR. By
default, this feature is disabled in all switches in the Cisco MDS 9000 Family. To begin configuring the
IVR feature, you must explicitly enable IVR on the required switches in the fabric.
The configuration and verification commands for the IVR feature are only available when IVR is enabled
on a switch. When you disable this configuration, all related configurations are automatically discarded.
Configuring an IVR Topology
This section explains the process used to create an IVR topology.
Creating an IVR Topology
You must create the IVR topology in every IVR-enabled switch in the fabric. You can have up to 64
VSANs in an IVR topology. Specify the IVR topology using the following information:

Cisco MDS 9000 Fabric Manager Switch Configuration Guide
16-4
To provide redundant paths between active IVZ members, IVR can (optionally) be enabled on
additional border switches.
The VSAN topology configuration must be updated before a border switch is added or removed.
Configure allowed-domains list using the Domain Manager MIBs so that the domains in different
VSANs are non-overlapping on all participating switches and VSANs.
Configure static, non-overlapping domains (using the CLI) for each participating switch and VSAN.
The switch WWNs of the IVR-enabled switches.
A minimum of two VSANs to which the IVR-enabled switch belongs.
