aptPolicy

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. 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.

switch:admin> aptpolicy

Current Policy: 3 1(ap)

3 1 (ap): Default Policy
