About IVR NAT and Auto Topology

Before configuring an IVR SAN fabric to use IVR NAT and auto-topology, consider the following
guidelines:
•
•
•
•
Note The IVR over FCIP feature is bundled with the Cisco MDS 9216i Switch and does not require the SAN
extension over IP package for the fixed IP ports on the supervisor module.
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).

Transit VSAN Guidelines

Consider the following guidelines for transit VSANs:

Border Switch Guidelines

Before configuring border switches, consider the following guidelines:

Configure IVR only in the relevant switches.
Enable CFS for IVR on all switches in the fabric.
Verify that all switches in the fabric are running Cisco MDS SAN-OS Release 2.1(1a) or later.
Acquire a mandatory Enterprise License Package or SAN-EXTENSION license package if you have
Cisco MDS SAN-OS Release2.1(1a) or later and one active IPS card for this feature (see
"Obtaining and Installing
Besides defining the IVR zone membership, you can choose to specify a set of transit VSANs to
provide connectivity between two edge VSANs:
If two edge VSANs in an IVR zone overlap, then a transit VSAN is not required (though, not
–
prohibited) to provide connectivity.
If two edge VSANs in an IVR zone do not overlap, you may need one or more transit VSANs
–
to provide connectivity. Two edge VSANs in an IVR zone will not overlap if IVR is not enabled
on a switch that is a member of both the source and destination edge VSANs.
Traffic between the edge VSANs only traverses through the shortest IVR path.
Transit VSAN information is common to all IVR zone sets. Sometimes, a transit VSAN can also act
as an edge VSAN in another IVR zone.
Border switches require Cisco MDS SAN-OS Release 2.1(1a) or later.
A border switch must be a member of two or more VSANs.
A border switch that facilities IVR communications must be IVR enabled.
