aptPolicy
2
• 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.
