I05. What is the difference between BWM (bandwidth management) in Policy
Route and App. Patrol ?
There are two places to set BWM policies:
1. Policy Route – The rule of Policy Route supports Outbound BWM only.
2. App. Patrol – App. Patrol supports both Outbound BWM and Inbound BWM.
If a traffic matches the BWM rules of both Policy Route and App. Patrol, Policy route will
be applied on the traffic.
