> # Enabling FC-SP on ISLs

> There is an ISL pop-up menu in DCNM-SAN called Enable FC-SP that enables FC-SP on switches at either end of the ISL. You are prompted for an FC-SP generic password, then asked to set FC-SP interface mode to ON for affected ports. Right-click an ISL and click Enable FC-SP to access this feature.

> Note FC-SP DHCHAP mode requires port-flap on both end of the ISL.
