The Address Resolution Protocol (ARP) table automatically maps the IP address to the MAC address of a switch. In addition to address information, the table shows the age of the entry in the table, the encapsulation method, and the switch interface (VLAN ID) where packets are forwarded. For example, the first entry in the sample ARP table below means that 180 minutes ago a switch with a MAC address of 0050.53f6.1240 was mapped to the Internet address 172.17.93.161 by using ARPA encapsulation. The switch belongs to VLAN 1.
Protocol | Address | Age (min) | Hardware Address | Type | Interface |
Internet | 172.17.93.161 | 180 | 0050.53f6.1240 | ARPA | VLAN 1 |
Internet | 192.168.29.43 | 12 | 0060.47d5.2754 | ARPA | VLAN 1 |
Internet | 172.29.65.216 | 6 | 0050.8037.ed81 | ARPA | VLAN 2 |
To display or remove all the addresses in the ARP table or to change the ARP cache timeout value, choose Administration > ARP and use the ARP window.
