5013 - Throttling traffic

Alarm Group:

IPFE

Description:

IPFE has seen traffic in excess of Global Packet Rate Limit and is dropping packets to throttle the traffic. To protect the DSR, IPFE defines a Global Packet Rate Limit set as a ingress signaling traffic rate throttle. The packet rate is accounted for on a per-local-port bases, thus each separate DSR listening port can receive each the default of 500,000 packets/second. When the IPFE is processing traffic in excess of this rate, the IPFE throttles the traffic by smoothly dropping packets in the manner of an overloaded border router. The default value of this rate throttle is 500,000 packets/second.

When traffic is approaching or exceeding its overload capacity, the alarm 5100 is raised and does not drop the packets. But when the traffic reaches this throttle, IPFE drops the packets
