1.1.3 ARP Table
In an Ethernet, the MAC addresses of two hosts must be available for the two hosts to
communicate with each other. Each host in an Ethernet maintains an ARP table, where
the latest used IP address-to-MAC address mapping entries are stored. S3100 series
Ethernet switches provide the display arp command to display the information about
ARP mapping entries.
ARP entries in an S3100 series Ethernet switch can either be static entries or dynamic
entries, as described in
Table 1-3.
Table 1-3 ARP entries
ARP entry Generation Method Maintenance Mode
Static ARP entry Manually configured Manual maintenance
Dynamic ARP entry Dynamically generated
ARP entries of this type age with
time. The aging period is set by
the ARP aging timer.
