aptPolicy 2 3 -ap ap_policy 0 1 Exchange-based routing policy (default). With this policy, the path chosen for an ingress frame is based on all of the following items: • The ingress port on which the frame was received. • The FC address of the source fabric device (SID) for this frame. • The FC address of the destination fabric device (DID) for this frame. • The FC Originator Exchange ID (OXID) for this frame. This policy optimizes the utilization of the available paths by allowing I/O traffic between different SID, DID, or OXID pairs to use different paths. All frames received on an ingress port with the same SID, DID, or OXID parameters take the same path unless there is a fabric event. Refer to dlsSet for the definition of a fabric event. This policy does not support static routes. DLS is always enabled and the DLS setting cannot change with this policy. Specifies an additional AP policy option supported under both port-based and exchange-based policies. If logical fabrics are enabled, this command is valid only on the base switch. The following policies are supported: AP Shared Link Policy (default). AP Dedicated Link Policy. This policy dedicates some links to the ingress traffic and some links to the egress traffic. This policy relieves internal congestion in an environment where there is a large amount of traffic going through both directions at the same time. In addition, it can reduce the impact of slow devices on the overall switch performance. Examples To display the current APT policy: switch:admin> aptpolicy Current Policy: 3 1(ap) 3 1 (ap): Default Policy 1: Port Based Routing Policy 3: Exchange Based Routing Policy 0: AP Shared Link Policy 1: AP Dedicated Link Policy To change the current APT policy to the AP Shared Link Policy: switch:admin> aptpolicy -ap 0 Switch must be disabled in order to modify this configuration parameter. To disable the switch, use the "switchDisable" command. switch:admin> switchdisable switch:admin> aptpolicy -ap 0 Policy updated successfully. switch:admin> switchenable switch:admin> aptpolicy Current Policy: 3 0(ap) 3 0(ap): Default Policy 1: Port Based Routing Policy 3: Exchange Based Routing Policy Fabric OS Command Reference 49 53-1001764-02
