Information About Virtual Domains
In a remote VSAN, the IVR application does not automatically add the virtual domain to the assigned domains list. Some switches (for example, the Cisco SN5428 switch) do not query the remote name server until the remote domain appears in the assigned domains list in the fabric. In such cases, add the IVR virtual domains in a specific VSAN to the assigned domains list in that VSAN. When adding IVR domains, all IVR virtual domains that are currently present in the fabric (and any virtual domain that is created in the future) will appear in the assigned domains list for that VSAN.
Tip |
Be sure to add IVR virtual domains if Cisco SN5428 or MDS 9020 switches exist in the VSAN.VSAN. Be |
When you enable the IVR virtual domains, links may fail to come up due to overlapping virtual domain identifiers. If this occurs, temporarily withdraw the overlapping virtual domain from that VSAN.
Note |
Withdrawing an overlapping virtual domain from an IVR VSAN disrupts IVR traffic to and from that domain. |
Use the ivr withdraw domain command in EXEC mode to temporarily withdraw the overlapping virtual domain interfaces from the affected VSAN.
Tip |
Only add IVR domains in the edge VSANs and not in transit VSANs. |
Licensing Requirements
Product | License |
---|---|
Cisco Nexus 7000 Series. | IVR requires the FCoE license for each F-series module. FCoE enabled in a storage VDC does not require the Advanced Services License. IVR also requires the Storage Enterprise License. For a complete explanation of the Cisco NX-OS licensing scheme and how to obtain and apply licenses, see the Cisco NX-OS Licensing Guide. |
Guidelines and Limitations
IVR has the following guidelines and limitations:
Default Settings
Parameters | Default |
---|---|
IVR feature | Disabled |
IVR NAT | Disabled |
IVR distribution | Disabled |
IVR Autotopology | Disabled |
IVR VSANs | Not added to virtual domains |
QoS for IVR Zones | Low |
Configuring IVR Virtual Domains
1. ivr virtual-fcdomain-add vsan-ranges vsan-range
2. (Optional) ivr commit
DETAILED STEPS
Verifying IVR Configuration
To display the IVR configuration, perform one of the following tasks:

show ivr diagnostics |
Displays information about IVR diagnostics. |
show ivr merge status |
Displays information the last IVR merge event. |
show ivr pending |
Displays information about the IVR pending database. |
show ivr pending-diff |
Displays the differences between the pending database and the config database. |
show ivr vsan-topology [active | configured] |
Displays the IVR VSAN topology. |
show ivr session status |
Displays information about IVR CFS session. |
show ivr virtual-domains |
Displays information about IVR virtual domains for all local VSANs. |
show ivr zone |
Displays information about IVR zones. |
show ivr zoneset |
Displays information about IVR zone sets. |
show ivr service-group active |
Displays information about the active service group. |
show ivr service-group configured | Displays information about the configured service group. |
show autonomous-fabric-id database | Displays information about the AFIDs. |
show ivr virtual-fcdomain-add-status | Displays the status of the IVR virtual domain configuration. |
