The following command can be used to display the dynamically learned ARP entries on an IP interface or on 
the entire system. 

The following command can be used to flush the dynamically learned ARP entries on an IP interface or on the 
entire system. 

The following command can be used to accept and process gratuitous ARP requests and replies. ARP requests 
and replies in which the target protocol address and sender protocol address are the same are considered. 
Because of security reasons, this feature is deactivated as default and must be enabled by the user.

Mode: configure

As an aid to diagnosing basic network connectivity, many network protocols support an echo protocol. The 
protocol involves sending a special datagram to the destination host, then waiting for a reply datagram from 
that host. Results from this echo protocol can help in evaluating the path-to-host reliability, delays over the 
path, and whether the host can be accessed or is functioning.

Display the ARP entries for the specified or all IP interfaces.

[name]#arp flush[<ip-if-name>]
