> # Assigning WWNs to iSLB Initiators

> An iSLB host is mapped to an N port’s WWNs by one of the following mechanisms:

> - Dynamic mapping (default)
> - Static mapping

> Note Assigning WWNs for iSLB initiators is the same as for iSCSI initiators. For information on dynamic and static mapping, see the "WWN Assignment for iSCSI Initiators" topic.

> Tip We recommend using the SystemAssign system-assign option. If you manually assign a WWN, you must ensure its uniqueness (see the Fabric Configuration Guide, Cisco DCNM for SAN for more information). You should not use any previously assigned WWNs.

> See the "Configuring iSLB Using Device Manager" procedure.
