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 6505 | Access Gateway Administrator's Guide 7.1.0 - Page 95
4 • Hosts 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 - Dell Brocade 6505 | Access Gateway Administrator's Guide 7.1.0 - Page 96
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.
