Access Gateway basic concepts
Access Gateway (AG) simplifies server and storage connectivity by enabling direct connection of servers to any SAN fabric—enhancing scalability by eliminating the switch domain identity and simplifying local switch device management.
Enabling Access Gateway mode
Enabling Access Gateway (AG) mode on a VDX switch allows FCoE hosts and devices behind LAG-supported FSBs connected to VF_Ports to connect to a FC fabric.
Disabling Access Gateway mode
Disabling Access Gateway (AG) mode returns the switch to native VCS mode. Disabling AG mode also removes all AG configuration, including port mapping and N_Port configuration.
VF_Port to N_Port mapping
To connect hosts attached to VDX Switch VF_Ports to Fibre Channel switch F_Ports, the appropriate VF_Ports must be mapped to VDX Switch N_Ports. Although ports have a factory-default mapping based on the VDX platform, you can change mapping using
Network OS commands.
Port Grouping policy
The Port Grouping (PG) policy partitions the VF_Ports, host, target ports within an Access Gateway-enabled switch into independently operated groups. Port Grouping allows you to dedicate specific hosts to specific fabric ports for performance, security, or other reasons.
Trunking in Access Gateway mode
The hardware-based Port Trunking feature enhances management, performance, and reliability of Access Gateway N_Ports connected to Brocade fabrics.
Access Gateway under FlexPort
FlexPort functionality enables specific ports to be dynamically reconfigured as either Fibre Channel (FC) or Ethernet ports, in several modes and speeds. This section deals with Access Gateway (AG) under FlexPort.
N_Port monitoring for unreliable links
N_Port monitoring monitors links between N_Ports on the switch configured in Access Gateway mode and F_Ports on the connected FC fabric. When links are considered unreliable, the N_Port is disabled.
