Configuration Guide NFPP Configuration
It prompts the following message when the IP scan was detected:
%NFPP_IP_GUARD-4-SCAN: Host<IP=1.1.1.1, MAC=
N/A,port=Gi4/1,VLAN=1> was detected. (2009-07-01 13:00:00)
The following example shows the describing information included in the sent
TRAP messages:
IP scan from host< IP=1.1.1.1, MAC= N/A,port=Gi4/1,VLAN=1> was detected.
Caution

It sets a policy to the hardware when isolating the attackers.
When the hardware resources have been exhausted, it
prompts the message to inform the administrator.

When it fails to allocate the memory to the detected
attackers, it prompts the message like
“
%NFPP_IP_GUARD-4-NO_MEMORY: Failed to alloc memory.
”
to inform the administrator.
This section shows the administrator how to configure the host-based rate-limit
and attack detection in the nfpp configuration mode and in the interface
configuration mode:
Command Function
Ruijie# configure terminal Enter the global configuration mode.
Ruijie(config)# nfpp
Enter the nfpp configuration mode.
Ruijie(config-nfpp)# ip-guard rate-limit
per-src-ip pps
Configure the ip-guard rate-limit,
ranging from 1 to 9999, 20 by default.
per-src-ip : detect the hosts based on
the source IP address/VID/port;
Ruijie(config)# ip-guard attack-threshold
per-src-ip pps
Configure the ip-guard attack
threshold, ranging from 1 to 9999, 20
by default. When the IP packet number
sent from a host exceeds the attack
threshold, the attack is detected and
IP-guard isolates the host, records the
message and sends the TRAP packet.

the source IP address/VID/port;
