Host Name:

Displays the Host Name.

IP Address:

Displays the IP Address of the Host.

MAC Address: Displays the MAC Address of the Host.

„

Warning: Indicates that a collision may be caused by the MSTP function.

 

„

Critical: Indicates that the Entry has caused a collision with other Entries.

 

CAUTION:

  IP-MAC Binding Table settings will be restored to defaults if 

the Switch is restarted and you have not selected Save Config 
from the main menu and saved your running configuration to 
non-volatile memory

 

NOTE:

  Among the entries with a Critical collision level, the entry with the 

highest Source Priority will take precedence.

 

NOTE:

  Among the conflicting entries with the same Source Priority, the 

last added or edited entry will take effect.

12.1.3 ARP Scanning

ARP (Address Resolution Protocol) is used to analyze and map IP Addresses to their 
corresponding MAC Addresses so that packets can be delivered to their destinations 
correctly and efficiently. An IP Address is the Address of a connected device on the 
Network Layer (Layer 3). A MAC Address is the Address of a connected device on 
the Data Link Layer (Layer 2) and is necessary for the packet to reach the device. The 
Destination IP Address carried in a packet needs to be translated into the corresponding 
devices MAC Address for data to be delivered.

ARP translates the IP Address into the corresponding MAC Address and maintains an 
ARP Table where the current IP Address-to-MAC Address mapping Entries are stored. 
When a known device communicates with an unknown device, ARP follows the outline 
in the figure shown below.
