ISL R_RDY Mode is enabled for port 3. Please make sure the PID
formats are consistent across the entire fabric.
Routing policies
By default, all routing protocols place their routes into a routing table. You can control the routes
that a protocol places into each table and the routes from that table that the protocol advertises by
defining one or more routing policies and then applying them to the specific routing protocol.
The routing policy is responsible for selecting a route based on one of three user-selected routing
policies:
• Port-based routing
• Exchange-based routing
• Device-based routing
Notes
Routing is handled by the FSPF protocol and routing policy.
Each switch can have its own routing policy and different policies can exist in the same fabric.
ATTENTION
For most configurations, the default routing policy is optimal and provides the best performance. You
should change the routing policy only if there is a significant performance issue, or a particular fabric
configuration or application requires it.
Displaying the current routing policy
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the aptPolicy command with no parameters.
The current policy is displayed, followed by the supported policies for the switch.
In the following example, the current policy is exchange-based routing (3) with the additional AP
Dedicated Link policy.
switch:admin> aptpolicy
Current Policy: 3
3 : Default Policy
1: Port Based Routing Policy
