must be an integer value from 1 through100.
Usage
Use this command to configure a threshold on the number of ICMP error messages sent by the subscriber for
a particular data flow. After the threshold is reached, it is assumed that the server is not reacting properly to
the error messages, and further downlink traffic to the subscriber on the unwanted flow is blocked.
Some servers that run QChat ignore the ICMP error messages (Destination Port Unreachable and Host
Unreachable) from the mobiles. So the mobiles continue to receive the unwanted UDP traffic from the QChat
servers, and their batteries get exhausted quickly.
