Disabling And Enabling Access Gateway Mode - IBM Brocade FCoE Installation And User Manual

Unlike AG in pure FC switches, port mapping in the high speed switch module proceeds from CEE
ports to (internal) FCoE ports to FC ports. Since there are 22 CEE ports (both internal and external)
and 22 FCoE ports (as a bridge from the CEE side of the high speed switch module to the FC side,
the port mapping is one-to-one and no user configuration is required. The 22 FCoE ports, however,
must be mapped to the 8 external FC ports. In AG mode the FCoE ports are functionally equivalent
to F_Ports and the FC ports are configured as N_Ports. The default port mapping configuration
assigns three F_Ports to each N_Port. However, in the high speed switch module you are not
restricted to this kind of grouping. You can assign any F_Port to any one of the N_Ports manually
through the CLI.

Disabling and enabling Access Gateway mode

This section provides steps to disable and enable Access Gateway mode using Fabric OS
commands. For more information on using these commands, refer to the "Enabling and disabling
Access Gateway mode" section in the Brocade Access Gateway Administrator's Guide or the
Brocade Fabric OS Administrator's Guide.
NOTE
You can also disable and enable Access Gateway mode using Web Tools. Refer to the See the Web
Tools Administrator's Guide for more information.
Enabling Access Gateway mode
Note the following when enabling AG mode:

Use the following steps to enable AG mode using Fabric OS commands. For more information on
enabling AG mode, refer to "Enabling and disabling Access Gateway mode" in the Brocade Access
Gateway Administrator's Guide.
1. Access the CLI for the high speed switch module.
2. Before disabling a switch to enable Access Gateway mode, save the current configuration file
3. Enter the switchShow command to verify the switch mode.
4. Enter switchDisable to disable the switch. AG mode can only be enabled or disabled when the
5. Enter ag –modeEnable to enable AG mode.
6. The switch reboots at this point so you must log back in to the switch.
7.

After you enable AG mode, some fabric information is erased, such as the zone and security
databases.
Enabling AG mode is disruptive because the switch is disabled and rebooted.
Ensure that no zoning or Admin Domain (AD) transaction buffers are active. If any transaction
buffer is active, enabling Access Gateway mode will fail with the error, "Failed to clear
Zoning/Admin Domain configuration."
