> # Enabling the iSNS Server

> Before the iSNS server feature can be enabled, iSCSI must be enabled (see the "Enabling iSCSI" topic). When you disable iSCSI, iSNS is automatically disabled. When the iSNS server is enabled on a switch, every IPS port whose corresponding iSCSI interface is up is capable of servicing iSNS registration and query requests from external iSNS clients.

> ## Detailed Steps

> To enable the iSNS server, follow these steps:

> 1. Choose End Devices > iSNS.

> You see the iSNS configuration in the Information pane.

> 2. Click the Control tab and select enable from the Command drop-down menu for the iSNS server feature.
> 3. Click the Apply Changes icon to save this change.

> Note If you are using VRRP IPv4 addresses for discovering targets from iSNS clients, ensure that the IP address is created using the secondary option (see "Adding Virtual Router IP Addresses" topic).
