Because Cisco switches do not support the Unzoned Name Server, Cisco
fabrics must be “pre-zoned” before you can set up TR mappings to a remote
Cisco fabric using the TR Mapping Manager dialog box. The Cisco fabric
zone set must be changed to add zones so that the WWNs of the remote
devices to be mapped and the WWNs of the QLogic 5800V Series Fibre
Channel Switch TR ports are zoned together. For more information, see the
Cisco documentation for specific information to configure zoning. Retain
these zones in the zone set after completion of the TR mapping as a best
practice, until you no longer need to map the device to the local fabric.
To configure transparent routing using QuickTools or Enterprise Fabric Suite:
1. Determine what devices on the local fabric require access to devices on the
remote fabric. Local devices must be attached directly to the QLogic 5800V
Series switch.
2. Configure one or more TR_Ports on the local QLogic 5800V Series switch
first and then connect the TR_Port to the remote fabric. The application
prompts you to configure TR_Ports where existing port connections to
remote fabrics have isolated. For remote Brocade or Cisco fabrics, the
switch to which the TR_Port connects must support N-Port ID Virtualization
(NPIV) and for Brocade fabrics the interoperability mode must be configured
to InteropMode=0. Other Brocade or Cisco switches in the remote fabric
need not support NPIV.
3. Map local devices to remote devices and activate the connection. The
mapping process creates an inter-fabric zone (IFZ) in the active zone set
consisting of the local device, the remote device, and the TR_Port. When
the mapping is complete, the new zone set is activated.
NOTE:
Be sure to configure the TR_Port before connecting the remote fabric
to the QLogic 5800V Series Fibre Channel Switch. If the remote fabric
is connected to a port on theQLogic 5800V Series Fibre Channel
Switch that is not a TR_Port, the two fabrics may establish an E_Port
connection and the local and remote fabrics may merge. This mixed
fabric is not a supported configuration. If the port type is changed to
TR_Port after connecting the remote fabric, a port reset may be
required to completely establish the TR connection.
