Use the access gateway mode if you have other vendor switch and don't want to use compatibility mode on all SAN switch. This will virtualized the brocade SAN switch, and all ISL to other SAN switches have to be configured as Nport (NPIV).

First disable the switch, no more activity on ports:

switch:admin> switchdisable
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 5on page 12.

Enter the ag –modeshowcommand to verify that AG mode is enabled.

switch:admin> ag --modeshow
Access Gateway mode is enabled.

Enter the ag –mapshowcommand to display all the mapped ports. The ag –mapshowcommand shows all enabled N_Ports,even if those N_Ports are not connected.

switch:admin> ag --mapshow

Enter the switchShowcommand to display the status of all ports. Note that the following output is an example only and may not exactly reflect output from the current Fabric OS.

switch:admin> switchshow

switchState: Online
switchMode: Access Gateway Mode

Change gateway mapping: Link F-ports “6;7” to an N-port “13”

switch:admin> ag --mapadd 13 "6;7"
