Chapter 22 Configuring Inter-VSAN Routing
IVR Zones and IVR Zone Sets
About Activating Zone Sets and Using the force Option
Once the zone sets have been created and populated, you must activate the zone set. When you activate
an IVR zone set, IVR automatically adds an IVR zone to the regular active zone set of each edge VSAN.
If a VSAN does not have an active zone set, IVR can only activate an IVR zone set using the force option,
which causes IVR to create an active zone set called “nozoneset” and adds the IVR zone to that active
zone set.
Caution
If you deactivate the regular active zone set in a VSAN, the IVR zone set is also deactivated. This occurs
because the IVR zone in the regular active zone set, and all IVR traffic to and from the switch, is stopped.
To reactivate the IVR zone set, you must reactivate the regular zone set.
Note
If IVR and iSLB are enabled in the same fabric, at least one switch in the fabric must have both features
enabled. Any zoning related configuration or activation operation (for normal zones, IVR zones, or iSLB
zones) must be performed on this switch. Otherwise, traffic might be disrupted in the fabric.
You can also use the
force
option to activate IVR zone sets.
Table 22-4
lists the various scenarios with
and without the
force
option.
Caution
Using the
force
option of IVR zone set activation may cause traffic disruption, even for devices that are
not involved in IVR. For example, if your configuration does not have any active zone sets and the
default zone policy is
permit
, then an IVR zone set activation will fail. However, IVR zone set activation
will go through if the
force
option is used. Because zones are created in the edge VSANs corresponding
to each IVR zone, traffic may be disrupted in edge VSANs where the default zone policy is
permit
.
