Collision
Displays the collision status of the entry.
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 from 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.
DHCP Snooping
With DHCP Snooping enabled, the switch can monitor the IP address obtaining process
of the host, and record the IP address, MAC address, VLAN ID and the connected port
number of the host.
