You can run the porttrunkarea command to assign - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 84
• A configuration file uploaded when the APC policy is enabled cannot be downloaded when the PG policy is enabled. F_Port trunks are not allowed on ICL ports. The porttrunkarea command does not allow it. You cannot create a Trunk Area on ports with different Admin Domains.

in conjunction with the Quality of Service (QoS) feature on Brocade fabrics. Fabric OS provides a mechanism to assign traffic priority, (high, medium, or low) for a given source and destination traffic flow. By default, all flows are marked as medium. You can configure the ingress rate limiting and - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 86
and procedures for configuring this feature, refer to "Ingress Limiting" in the Fabric OS Administrator's Guide.

use. For a complete list of the standard, pre-defined frame types, see the fmMonitor command description in the Fabric OS Command 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 - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 90
an AG switch: • The Top Talker and ISL monitoring features used for APM in switch mode are not supported on an AG switch. • APM on an AG switch is not supported in Web Tools. • Configuration file upload and download of end-to-end and filter monitor configurations is not supported in the Fabric OS v7 - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 91
if MFNM is enabled 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 - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 92
For other AG platforms, this command restores the port configuration to factory default values. Considerations for the Brocade 6505 and 6510 The Brocade 6505 and 6510 can function in either Fabric OS Native mode or Brocade Access Gateway mode.These switches are shipped in Fabric OS Native mode.

in Access Gateway (AG) mode, and discusses Edge switch compatibility, target aggregation, direct target attachment, port requirements, NPIV HBA, and interoperability. Switches in AG mode can connect to third-party fabrics with the following firmware versions: • M-EOSc v9.6.2 or later and M-EOSn v9 - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 94
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 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 95
and targets should be in separate port groups. • Direct target attachment configurations are not enforced. Target aggregation Access Gateway mode is normally used as host aggregation. In other words, a switch in AG mode aggregates traffic from a number of host systems onto a single uplink N_Port - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 96
of hosts to fabric ports to beyond what a single switch in AG mode can support. Access Gateway cascading allows you to link two Access Gateway (AG) switches back to back. The AG switch that is directly connected to the fabric is referred to as the Core AG. In this document, the AG switch connected - Dell Brocade 6510 | Access Gateway Administrator's Guide 7.1.0 - Page 97
