then a HARD OIR or process kill might be required.

• CSCue34618
Symptoms: Traffic stops flowing with combination of BRR and policer: in different class-maps
under a policy.
Conditions: When the BW remaining ratio is configured in combination of police with cir (total brr
and police cir equal to 1000M):
Workaround: Configuring total of BRR and police cir <1000M works fine: Ex: class A Police cir
100m and class B BRR 90% fails but BRR 89% works fine

Symptoms: Policy-map attached on the PC interface stops working after service instance is
removed and re-configured.

working when the service instance from the interface is deleted dynamically and then re-configured.
Workaround: Remove and re-attach the policy-map on the PC interface

links from which traffic was flowing. The traffic gets redirected but the QoS is no longer working
Workaround: Remove policy from all the member links and then reattach
