• Exchange-based routing policy With this policy, the path chosen for an ingress frame is based on: Ingress port on which the frame was received • FC address of the SID for this frame • FC address of the DID for this frame • FC Originator Exchange ID (OXID) for this frame This policy allows for optimal utilization of the available paths as I/O traffic between different (SID, DID, OXID) pairs can use different paths. All frames received on a ingress port with the same (SID, DID, OXID) parameters takes the same path unless there is a fabric event. See dlsSet for the definition of a fabric event. This policy does not support static routes. DLS always is enabled and the DLS setting cannot change with this policy. Examples To display the current policy and then change it from an exchange-based to a device-based policy: switch:admin> aptpolicy Current Policy: 3 3: Default Policy 1: Port Based Routing Policy 2: Device Based Routing Policy 3: Exchange Based Routing Policy switch:admin> aptpolicy 2 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 2 Policy updated successfully. switch:admin> switchenable switch:admin> aptpolicy Current Policy: 2 3: Default Policy 1: Port Based Routing Policy 2: Device Based Routing Policy 3: Exchange Based Routing Policy 50 Fabric OS commands
