Access Gateway (AG) Fabric OS mode for embedded switches that reduces SAN (storage area network) deployment complexity by leveraging NPIV (N_Port ID virtualization).

    DCC policy in the enterprise fabric should include N_Port WWN and port WWNs of all F_Ports on Access Gateway mapped to that N_Port. In case of DCC policy violation, the port in the enterprise fabric to which N_Port is connected will be disabled. This will bring down the corresponding N_Port and F_Ports mapped to it on Access Gateway.

    N_Port to an edge fabric switch. Using N_Port ID virtualization (NPIV), Brocade Access Gateway allows multiple FC initiators to access the SAN on the same physical port. This reduces the hardware requirements and management overhead of hosts to the SAN connections.

  • Page 14: Port Mapping

    Port mapping Brocade Access Gateway uses mapping—that is, pre-provisioned routes—to direct traffic from the hosts to the fabric. When you first enable Access Gateway mode, the F_Ports are mapped to a set of predefined N_Ports, see Appendix A, “Default Port Mapping”.

  • Page 15: Port Initialization

    Switch_B F_B2 Port initialization To ensure that all hosts are brought online when Brocade Access Gateway starts up, the ports are initialized in the following manner: 1. All N_Ports are initialized. During N_Port initialization all the F_Ports are disabled (kept OFFLINE).

  • Page 16: Failover Policy

    Host log in request Failover policy The Brocade Access Gateway N_Port failover policy allows hosts to automatically remap to an online N_Port if the N_Port they are connected to goes offline. The failover policy evenly distributes the F_Ports that are mapped to an offline N_Port among all the online N_Ports. The failover policy is a parameter of each N_Port.

Example: Failback Policy In Example 3, the Brocade Access Gateway N_1 remains disabled because the corresponding F_A1 port is offline. However N_2 comes back online. See Figure 5 on page 7 for the original failover scenario.

  • Page 20: Enabling Access Gateway Mode

    NOTE On the 200E, you must enable all ports using POD licensing before enabling Access Gateway mode. USING THE CLI TO ENABLE ACCESS GATEWAY MODE Enabling Access Gateway mode is a disruptive process; the switch is disabled and rebooted. Once you enable Access Gateway mode, only a limited subset of Fabric OS commands are available and all fabric-related service requests are forwarded to the fabric switches.
  • Page 21 5. Enter the ag modeenable command to enable Access Gateway mode. switch:admin> ag --modeenable The switch automatically reboots and comes back online in Access Gateway mode using a factory default F_Port to N_Port mapping. See Appendix A, “Default Port Mapping”.
  • Page 22 Enabling Access Gateway mode Enter the ag mapshow command without any options to display all the mapped ports. The following example shows a mapping that has been reconfigured, three N_Ports 17, 19 and 20 have no mappings and are not connected to the fabric.

    Notes on joining the switch to a fabric After the switch reboots when Access Gateway mode is disabled, the default zone is set to no access. Therefore the switch does not immediately join the fabric to which it is connected. Use one of the following methods to join the switch to the fabric: •...

    CAUTION If the failback policy is enabled and autofailback occurs, this will interrupt traffic because the ports need to relogin to their original mapped port thus causing a disruption in traffic. Access Gateway Administrator’s Guide 53-1000633-01...

  • Page 32: Enabling The Failover Policy

    Failover policy is disabled for port 13 ENABLING THE FAILBACK POLICY A switch in Access Gateway mode supports automatic F_Port failback to N_Ports when that port comes back online. By default the failback policy is enabled. When an N_Port with an enabled failback policy comes back online, the F_Ports that were originally mapped to it are automatically rerouted back to the N_Port.

    4. Connect the HBA, host, or other FCP initiator to the F_Port NOTE A switch in Access Gateway mode must have at least one port configured as an N_Port. Therefore the maximum number of F_Ports that could be mapped to an N_Port is the number of ports on the switch minus one.
