Fabric OS 5.0.0 command reference guide 49
• Device-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 source fabric device (SID) for this frame
• FC address of the destination fabric device (DID) for this frame
This policy allows for better utilization of the available paths as I/O traffic
between different (SID, DID) pairs can use different paths. All frames received
on a ingress port with the same (SID, DID) parameters takes 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 always is enabled and the DLS
setting cannot change with this policy.
• 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. Refer to 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.
