Typically, fabric switches connect to the Enterprise fabric using interswitch link (ISL) ports, such as E_Ports. AG uses the following Fibre Channel (FC) ports - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 30

reboots and firmware upgrades. • This feature supports virtual switches, so each port can have a specific NPIV login limit value in each logical switch. • The login limit default is 126. This value will be set for a port when the portCfgDefault command is used to reset port default values. • Before - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 88

Reference Manual. To enable frame monitoring, you must install a frame monitor on an F_Port or N_Port in the AG switch using the fmMonitor command. Using options in this command, you can also perform the following tasks: • Create a new frame type. • Delete a specified frame type. • Delete the set of - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 90
Fibre Channel ports are configured as N_Ports. For details on how this affects port mapping, refer to "Brocade 8000 mapping differences" on page 19. Policy and feature support The following AG policies and features are not supported on the Brocade 8000: • Connection to multiple fabrics. The Brocade - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 91
on the entire switch and multiple fabrics are connected to the switch. Fabric OS command support This section describes how Fabric OS commands are supported on the Brocade 8000 in AG mode. • The following commands are not supported on the Brocade 8000 in AG mode: - ag --pgmapadd - ag --pgmapdel - ag - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 92
6505 and 6510 • The following commands have restricted usage, mostly because the Brocade 8000 contains only eight Fibre Channel ports and does not support the Automatic Port Configuration policy: - ag --pgcreate - ag --policyenable - ag --policydisable - portcfgdefault • To enable or disable FCoE - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 93
devices and FICON channels/control unit connectivity are not supported. • When a switch is in AG mode, it can be connected to NPIV-enabled HBAs, or F_Ports that are NPIV-aware. Access Gateway supports NPIV industry standards per FC-LS-2 v1.4.

supported if the AG module is also connected to a core fabric. A switch module running in AG mode does not provide Name Services on its own, and routing to the target devices must be established by the core fabric. • Hosts and targets cannot be mapped to the same N_Port. • Redundant configurations - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 95
with various lower Fibre Channel speeds (such as 1, 2, or 4 Gbps) onto a single high-speed uplink port to the core fabric. This reduces the number of core fabric ports used by target devices and allows higher scalability.

manual before performing these procedures. • Verify that the interop mode parameter is set to Brocade Native mode. • Configure the F_Ports on the Edge switch to which Access Gateway is connected as follows: - Enable NPIV. - Disable long distance mode. - Allow multiple logins for M-EOS switches - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 98
, you can enable AG mode; otherwise, set the switch to Native mode, and then reboot the switch. Enabling NPIV on M-EOS switches 1. Connect to the switch and log in as admin on the M-EOS switch. 2. Enable Open Systems Management Server (OSMS) services by entering the following commands. For the Mi10K - Dell Brocade M5424 | Brocade 7.1.0 Access Gateway Administrator's Guide - Page 99
