aptPolicy
2
3
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.
-ap ap_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:
0
AP Shared Link Policy (default).
1
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.
