Fabric OS 5.x command reference guide
49
Changes or displays the Advanced Performance Tuning (APT) policy.
Synopsis
aptpolicy
[
policy
]
Availability
admin
Description
Use this command, which changes several internal parameters, to change the performance algorithm on
the switch. (A detailed performance-tuning discussion is beyond the scope of this manual.) The default
parameters are optimal for most SAN applications; typically, customers do not need to use this
command.
When used with no arguments, this command displays a list of APT policies supported on this switch, as
well as the current policy. This can be done at any time.
The switch must be disabled before using this command to change the current policy.
Operands
This command has the following operand:
aptPolicy
policy
Specifies the new APT policy. The following polices are supported:
•
Port-based routing policy
With this policy, the path chosen for an ingress frame is based on:
• Ingress port on which the frame was received
• Destination domain for the frame
The chosen path remains the same if Dynamic Load Sharing (DLS) feature is
not enabled. If DLS is enabled, then a different path may be chosen on a
fabric event. See
dlsSet
for the definition of a fabric event.
This policy may provide better ISL utilization when there is little or no
oversubscription of the ISLs.
Note that static routes are supported only with this policy.
•
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. 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.
