that you enable on a switch using the ag command. After a switch is set in ag mode, it can connect to the fabric using node ports (N_Ports). Typically fabric switches connect to the Enterprise fabric using ISL (InterSwitch Link) ports, such as E_Ports. Following are the Fibre Channel (FC) ports that - HP StorageWorks 8/24 | Brocade Access Gateway Administrator's Guide v6.3.0 (53-1 - Page 25
