Caution
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.
To configure the iSLB initiator optional auto-zone name and activate the zone set, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# islb initiator ip-address
10.1.1.3
switch(config-islb-init)#
Step 3
switch(config-islb-init)# zonename IslbZone
switch(config-islb-init)# no zonename
IslbZone
Step 4
switch(config-islb-init)# exit
Step 5
switch(config)# islb zoneset activate
Verifying iSLB Zoning Configuration
The following example shows the show zoneset active command output when the dynamically
generated zone name is used.
switch# show zoneset active
zoneset name zoneset-1 vsan 1
zone name ips_zone_5d9603bcff68008a6fc5862a6670ca09 vsan 1
* fcid 0x010009 [ip-address 10.1.1.3]
...
The following example shows the show zoneset active command output when the configured zone name
IslbZone is used.
switch# show zoneset active
zoneset name zoneset-1 vsan 1

Auto-zoning of the initiator with the initiator targets is enabled by default.
A zone set must be active in a VSAN for auto-zones to be created in that VSAN.
iSLB zone set activation might fail if another zone set activation is in process or if the zoning
database is locked. Retry the iSLB zone set activation if a failure occurs. To avoid this problem, only
perform only one zoning related operation (normal zones, IVR zones, or iSLB zones) at a time.
Auto-zones are created when the zone set is activated and there has been at least one change in the
zoneset. The activation has no effect if only the auto-zones have changed.

Purpose
Enters configuration mode.
Configures an iSLB initiator using its IPv4 address
and enters iSLB initiator configuration submode.
Specifies the zone name where the initiators and
the initiator targets are added (optional).
Removes the initiators and initiator targets from
the zone and adds them to a dynamically created
zone (default).
Returns to configuration mode.
Activates zoning for the iSLB initiators and
initiator targets with zoning enabled and creates
auto-zones if no zone names are configured.
Note
This step is not required if CFS is enabled.
CFS automatically activates the zone when
the configuration changes are committed.
