Route selection

Routing in Virtual Fabrics
Virtual Fabrics support DPS on all partitions. DPS is limited where multiple paths are available for a
logical fabric frame entering a Virtual Fabrics chassis from a base fabric that is sent out using one
of the dedicated ISLs in a logical switch.
The AP policy affecting the DPS behavior, whether it is exchange-based, device-based, or
port-based, is configured on a per-logical switch basis. In-order delivery (IOD) and DLS settings are
set per logical switch as well. IOD and DLS settings for the base switch affect all traffic going over
the base fabric including any logical fabric traffic that uses the base fabric.
CAUTION
Setting the routing policy is disruptive to the fabric because it requires that you disable the switch
where the routing policy is being changed.
Setting the routing policy
1. Connect to the VF switch and log in as admin.
2. Enter the setcontext command for the correct FID.
3. Enter the switchDisable command to disable the switch.
4. Take the appropriate following action based on the AP route policy you choose to implement:
Setting up the AP route policy
The AP route policy can only be set in the base switches that are using Virtual Fabrics.
1. Connect to the base switch and log in as admin.
2. Enter the switchDisable command to disable the switch.
3. Take the appropriate following action based on the AP route policy you choose to implement:

Route selection

Selection of specific routes can be dynamic, so that the router can constantly adjust to changing
network conditions; or it may be static, so that data packets always follow a predetermined path.
