> # Configuring iSLB Using Device Manager

> ## Prerequisites

> Perform the following actions prior to configuring iSLB:

> - Enable iSCSI (see the "Enabling iSCSI" topic for more information).
> - Configure the Gigabit Ethernet interfaces (see the "Configuring Gigabit Ethernet Interface" topic).
> - Configure the VRRP groups (see the "Configuring Load Balancing Using VRRP" topic).
> - Configure and activate a zone set (see the Fabric Configuration Guide, Cisco DCNM for SAN for more information).
> - Enable CFS distribution for iSLB (see the "Enabling iSLB Configuration Distribution" topic).

> ## Detailed Steps

> To configure iSLB using Device Manager, follow these steps:

> 1. Choose IP > iSCSI iSLB.

> You see the iSCSI iSLB dialog box.

> 2. Click Create to create a new iSCSI iSLB initiator.

> You see the Create iSCSI iSLB Initiators dialog box.

> 3. Set the Name or IP Address field to the iSLB name or IP address.
> 4. Set the VSAN Membership field to the VSAN that you want the iSLB initiator in.

> Also see the "Assigning VSAN Membership for iSLB Initiators" topic.

> 5. Check the Persistent check box to convert a dynamic nWWN to static for the iSLB initiator.

> Also see the "Making the Dynamic iSCSI Initiator WWN Mapping Static" topic.

> 6. (Optional) Check the SystemAssigned check box to have the switch assign the nWWN.
> 7. (Optional) Set the Static WWN field to manually assign the static nWWN. You must ensure uniqueness for this nWWN.
> 8. (Optional) Check the Port WWN Mapping Persistent check box to convert dynamic pWWNs to static for the iSLB initiator.

> See the "Making the Dynamic iSCSI Initiator WWN Mapping Static" topic.

> 9. (Optional) Check the SystemAssigned check box and set the number of pWWNs you want to have the switch assign the PWWN.
> 10. (Optional) Set the Static WWN(s) field to manually assign the static pWWNs.

> You must ensure uniqueness for these pWWN.

> 1. (Optional) Set the AuthUser field to the username that you want to restrict the iSLB initiator to for iSLB authentication.

> Also see the "Restricting iSLB Initiator Authentication" topic.

> 2. Fill in the Username and Password fields to configure iSLB initiator target CHAP authentication.

> Also see the "iSLB Session Authentication" topic.

> 1. In the Initiator Specific Target section, set the pWWN to configure an iSLB initiator target.
> 2. (Optional) Set the Name field to a globally unique identifier (IQN).
> 3. (Optional) Check the NoAutoZoneCreation check box to disable auto-zoning.
> 4. (Optional) Check the TresspassMode check box.

> Also see the "LUN Trespass for Storage Port Failover" topic.

> 5. (Optional) Check the RevertToPrimary check box to revert back to the primary port after an HA failover when the primary port comes back up.
> 6. Set the PrimaryVsan to the VSAN for the iSLB initiator target.
> 7. Click Create to create this iSLB initiator.
> 8. If CFS is enabled, select commit from the CFS drop-down menu.
