Q:
How does AR1200&2200&3200 configure current limiting?

Alarm Information

Handling Process

A:
1. AR1200&2200&3200 have two current limiting ways, one is by qos car, another is by traffic policy.
2. The difference between two ways: qos limits current by port that cannot specify acl, but traffic policy can add acl, more flexible.
3. If configure qos car and traffic policy at the same time, traffic policy before qos car, traffic policy enable first.
4. Research & Development dept commend cir,cbs and pbs whose inverse proportion is 1:188:313, for example, input qos car inbound cir 4000 when limiting current, it will display qos car inbound cir 4000 cbs 752000 pbs 1252000 green pass yellow pass red discard automaticly. This is the best value commended by Research & Development dept.
