Enabling Access Gateway mode

Enabling Access Gateway (AG) mode on a VDX switch allows FCoE hosts and devices behind LAG-supported FSBs connected to VF_Ports to connect to a FC fabric.

On supported devices, Access Gateway mode is enabled by default.

Enabling AG mode enables FC ports on the switch, configuring them as N_Ports. The N_Ports can connect directly to F_Ports on an edge FC switch. VF_Ports are mapped to N_Ports in a sequential, round-robin fashion as Enodes log in. You can change this default mapping using Network OS commands.

Before enabling or disabling AG mode, ensure that the following conditions are fulfilled:
  • All Fibrechannel interfaces are in shut state.
  • There are no ports provisioned for FCoE.
  • The RBridge ID of the switch is not specified in the FCoE forwarder (FCF) configuration.

Use the following procedure to enable Access Gateway mode.

  1. Enter the configure terminal command to change to global configuration mode.
    device# configure terminal
  2. Enter the rbridge-id command, specifying the RBridge ID.
    device(config)# rbridge-id 1
  3. Enter the ag command to change to AG configuration mode.
    device(config-rbridge-id-1)# ag
  4. Enter the the enable command.
    device(config-rbridge-id-1-ag)# enable
    AG mode is enabled. Switch FC ports are automatically enabled as N_Ports and mapped to VF_Ports.
You can configure additional FC port attributes for the N_Ports as you would on switches in native mode. Refer to Configuring Fibre Channel Ports.
