About Fibre Channel Common Transport
With the FC-CT management security feature, you can configure the network in such a manner that only a storage administrator or a network administrator can send queries to a switch and access information such as devices that are logged in devices in the fabric, switches in the fabric, how they are connected, how many ports each switch has and where each port is connected, configured zone information and privilege to add or delete zone and zone sets, and host bus adapter (HBA) details of all the hosts connected in the fabric.
In Cisco MDS NX-OS Release 6.2(9), the FC management feature is disabled by default. To enable FC management feature, use the fc-management enable command.
You can configure which pWWNs can send FC-CT management query and modify request to the management server. When any of the modules, such as a zone server, unzoned Fibre Channel name server (FCNS), or Fabric Configuration Server (FCS) receives an FC-CT management query, they perform a read operation on the FC-management database. If device is found in FC-management database, a reply is sent according to the permissions granted. If the device is not found in the FC-management database, each module sends a reject. If FC-management is disabled, each module processes each management query.
