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 WSS. A switch adds an entry for its own MAC address and adds entries for addresses
learned from traffic received by the WSS. When the WSS 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 WSS and cannot be disabled.
