Chapter 4 Configuring the Address Resolution Protocol

Showing ARP Information

•summary - Displays the total number of static entries, total number of dynamic entries, and total number of entries in the ARP resolution table, excluding the entries from the CSS management port.

•ip_or host - The IP address for the system to display its resolution. Enter the address in dotted-decimal format (for example, 192.168.11.1) or mnemonic host-name format (for example, myname.mydomain.com). You cannot enter an ARP entry derived from the CSS Ethernet management port.

For example, to display the complete ARP resolution table, enter:

#show arp

Field

Description

 

 

IP Address

The IP address of the system for ARP mapping.

 

 

MAC Address

The MAC address of the system mapped to the IP address.

 

 

Type

The resolution type for the entry: Dynamic or Static. The

 

Dynamic resolution type indicates that the entry was

 

discovered through the ARP protocol. The Static

 

resolution type indicates that the entry is from a static

 

configuration.

 

 

Port
