Each host in an Ethernet maintains an ARP table, wherethe latest used IP address-to-MAC address mapping entries are stored. S3100 seriesEthernet switches provide the display arp command to display the information aboutARP mapping entries.ARP entries in an S3100 series Ethernet switch can either be static entries or dynamicentries, as described in Table 1-3.Table 1-3 ARP entriesARP entry Generation Method Maintenance ModeStatic ARP entry Manually configured Manual maintenanceDynamic ARP entry Dynamically generatedARP entries of this type age withtime. The aging period is set bythe ARP aging timer.
