Check the check box next to each switch involved in IVR that you want to use this default AFID.

Provide a name for each SwitchWWN and set the Fabric ID.

Enter a comma-separated list of VSAN IDs in the VSAN List text box.

Configuring IVR Without IVR NAT or Auto Topology

Before configuring an IVR SAN fabric without IVR in NAT mode or IVR topology in auto mode,
consider the following guidelines:
•
•
•
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.
Note IVR-enabled VSANs can be configured when the interop mode is enabled (any interop mode) or disabled
(no interop mode).

Domain ID Guidelines

Domain IDs must be unique across inter-connected VSANs when not using IVR NAT. To ensure unique
domain IDs across inter-connected VSANs, consider these guidelines:
•
•
You can configure domain IDs using one of two options:
•

Step 1 through Step 6 for all switches and AFIDs you want to configure in your IVR topology.
Configure unique domain IDs across all VSANs and switches participating in IVR operations if you
are not using IVR NAT. 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 SAN-EXTENSION license package and one
active IPS card for this feature.
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.
Configure the allowed-domains list so that the domains in different VSANs are non-overlapping on
all participating switches and VSANs.
Configure static, non-overlapping domains for each participating switch and VSAN.
