Switch Show Commands

switch show arp

To display entries in the ARP table, use the switch show arp command in privileged EXEC mode.

switch show arp

Syntax Description

This command has no arguments.

Command Modes

Privileged EXEC (#)

Command History

Release Modification
3.5.1

This command was introduced.

Usage Guidelines

The Interface field can be empty because the associated interface of a MAC address can be aged out from the FDB table.

If an ARP entry is associated with an IP interface that is defined on a port or port channel, the VLAN field is empty.

Examples

The following example displays entries in the ARP table: 


nfvis# switch show arp
