Managing the ARP Table
The Address Resolution Protocol (ARP) table maps IP addresses to MAC addresses. An
ARP entry enters the table in one of the following ways:
• Added automatically by the Switch. A switch adds an entry for its own MAC address
and adds entries for addresses learned from traffic received by the switch. When the
switch receives an IP packet, the switch adds the packet’s source MAC address and
source IP address to the ARP table.
• Added by the system administrator. You can add dynamic, static, and permanent
entries to the ARP table.
ARP is enabled by default on a switch and cannot be disabled.
