Configuring IPWATCHD

The IP WATCH Daemon (IPWATCHD) provides the function of detecting active or
passive IP collision. Regardless of IP collision attacker or victim, the information including
source ip/mac is transmitted as an evm fault event when the IP collision occurs. At the
collision time, the Gratuitous Address Resolution Protocol (GARP) reply is transmitted 3
times to the unicast at every 1 second.
It supports the rate-limit function to deal with an intended ARP attack. Although ARP is
entered from a host that is not in the same subnet, it generates GARP by recognizing it as
a target if the host has the same APC IP.
Configuration using CLI
To configure the IPWATCHD function, enter into the configure mode of CLI.
Configure a TIMEOUT value (that a user wants) to detect an IP address collision.
