Command History
Usage Guidelines In a complex network topology, you might only have a few IVR-enabled VSANs. To reduce the amount
of traffic to non-IVR-enabled VSANs, you can configure a service group that restricts the traffic to the
IVR-enabled VSANs. A service group is a combination of AFIDs and VSANs. Up to 16 service groups
can be configured. A VSAN or AFID can belong to just one service group. When a new IVR-enabled
switch is added to the network, you must update the service group to include the new VSANs.
There can be a maximum of 128 AFID/VSAN combinations in all service group. However, all 128
combinations can be in one service group.
The default service group ID is 0. The default service group is for all VSANs that are not a part of a
user-defined service group.
Before configuring an IVR service group, you must enable the following:
• IVR using the ivr commit command
• IVR distribution using the ivr commit command
• Automatic IVR topology discovery using the ivr commit auto command.
Using the autonomous-fabric-id (IVR topology database configuration) command, you can restrict
the IVR traffic to the AFIDs and VSANs configured in the service group.
Examples The following example shows how to configure an IVR service group and change to IVR service group
configuration mode.
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# ivr enable
switch(config)# ivr vsan-topology auto
