About the IVR Zone Wizard
Note IVR topology in auto mode requires Cisco MDS SAN-OS Release 2.1(1a) or later and enabling CFS for
IVR on all switches in the fabric.
Autonomous Fabric ID
The autonomous fabric ID (AFID) distinguishes segmented VSANS (that is, two VSANs that are
logically and physically separate but have the same VSAN number). Cisco MDS NX-OS supports AFIDs
from 1 through 64. AFIDs are used in conjunction with auto mode to allow segmented VSANS in the
IVR VSAN topology database. You can configure up to 64 AFIDs.
The AFID can be configured individually for each switch and list of VSANs, or the default AFID can be
configured for each switch.
Note Two VSANs with the same VSAN number but different AFIDs are counted as two VSANs out of the
total 128 VSANs allowed in the fabric.
IVR Interoperability
When using the IVR feature, all border switches in a given fabric must be Cisco MDS switches.
However, other switches in the fabric may be non-MDS switches. For example, end devices that are
members of the active IVR zone set may be connected to non-MDS switches. Non-MDS switches may
also be present in the transit VSAN(s) or in the edge VSANs if one of the interop modes is enabled.
See the “Switch Interoperability” section on page 37-8.
About the IVR Zone Wizard
The IVR Zone Wizard simplifies the steps required to configure IVR zones in a fabric. The IVR Zone
Wizard checks the following conditions and prompts you for any issues:
• Checks if all switches in the fabric are Cisco MDS SAN-OS Release 2.1(1a) or later and if so, asks
if you want to migrate to using IVR NAT with auto-topology.
• Checks if any switches in the fabric are earlier than Cisco MDS SAN-OS Release 2.1(1a) and if so,
asks you to upgrade the necessary switches or to disable IVR NAT or auto-topology if they are
enabled.
Configuring IVR Using the IVR Zone Wizard
To configure IVR and IVR zones using the IVR Zone Wizard in Fabric Manager, follow these steps:
Step 1 Click the IVR Zone Wizard icon in the Zone toolbar (see Figure 29-2).
