Displaying dynamic ARP entries

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

Flushing dynamic ARP entries

The following command can be used to flush the dynamically learned ARP entries on an IP interface or on the
entire system.
Step Command
1 [name]#arp flush[<ip-if-name>]

Processing gratuitous ARP requests

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
Step Command
1 [name](cfg)#[no] arp gratuitous

Testing connections with the ping command

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.
