Overview

IVR allows resources to be shared across VSANs without compromising other VSAN benefits.
Troubleshooting IVR involves checking the configuration of domain IDs, VSANs, border switches, and
zone sets. Configuration problems with IVR can prevent devices from communicating properly.
Prior to Cisco MDS SAN-OS Release 2.1(1a), IVR required unique domain IDs for all switches in the
fabric. As of Cisco MDS SAN-OS Release 2.1(1a), you can enable IVR Network Address Translation
(NAT) to allow non-unique domain IDs. This feature simplifies the deployment of IVR in an existing
fabric where non-unique domain IDs might be present.
By default, IVR-NAT is not enabled.
