The following example shows how to bind an entry with the hostname host1, IP address 192.168.0.55, MAC address AA-BB-CC-DD-EE-FF, VLAN ID 10, port number 1/0/5, and enable this entry for the ARP detection feature.

There are two types of collision status: Warning and Critical. Warning: The collision entries have the same IP address and MAC address, and all the collision entries are valid. This kind of collision may be caused by the MSTP function. Critical: The collision entries have the same IP address but different MAC addresses. For the collision entries learned from the same source, only the newly added entry will be valid. For the collision entries learned different sources, only the entry with the highest priority will be valid. The priority of different entry types, from high to low, is Manually, ARP Scanning and DHCP Snooping. Configuration Guide 576
