Enabling and disabling Access Gateway mode

Use the following steps to enable and disable Access Gateway mode. 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. For more information on the

commands

used in these steps, refer to the

Fabric OS Command Reference

Before enabling or disabling a switch to AG mode, save the current configuration file using the

configupload

command in case you might need this configuration again.

Ensure that no zoning or Admin Domain (AD) transaction buffers are active. If any transaction

buffer is active, enabling AG mode will fail with the error, “Failed to clear Zoning/Admin Domain

configuration”.

Verify that the switch is set to Native mode or

interopmode 0

Issue the

switchshow

command to verify the switch mode.

If the switch mode is anything other than 0, issue the

interopmode 0

command to set the

switch to Native mode.

For more information on setting switches to Native mode, refer to the

Fabric OS Administrator’s

Guide

Enter the

switchdisable

command.

switch:admin>

switchdisable

This command to disables all user ports on a switch. All Fibre Channel ports are taken offline.

If the switch was part of a fabric, the remaining switches reconfigure. You must disable the

switch before making configuration changes.

Enter the

modeenable

command.

switch:admin>

ag --modeenable

The switch automatically reboots and comes back online in AG mode using a factory default

port mapping. For more information on AG default port mapping, see

Table 5

on page 12.

Enter the

modeshow

command to verify that AG mode is enabled.

switch:admin>

ag --modeshow

Access Gateway mode is enabled.
