Port-based rate-limit and attack detection
You can configure the icmp-guard rate limt and attack threshold on the port. The
rate limit value must be less than the attack threshold value. When the ICMP
packet rate on a port exceeds the limit, the ICMP packets are dropped. When
the ICMP packet rate on a port exceeds the attack threshold limit, the CLI
prompts and the TRAP packets are sent.
It prompts the following message when the ICMP DoS attack was detected on a
port:
%NFPP_ICMP_GUARD-4-PORT_ATTACKED: ICMP DoS attack was detected
on port Gi4/1. (2009-07-01 13:00:00)
The following is additional information of the sent TRAP packet :
ICMP DoS attack was detected on port Gi4/1.
This section shows the administrator how to configure the port-based rate-limit
and attack detection in the nfpp configuration mode and in the interface
configuration mode:

Ruijie(config)# icmp-guard
attack-threshold per-port pps
Configure the icmp-guard attack
threshold, ranging from 1 to 9999. The
