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

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

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.
Mode: Either operator or administrator execution
Step Command
1 node#ping <address> [<num-
ber> ] [timeout <seconds> ]
[packet-size <packet-size> ] [ttl
<ttl> ] [traffic-class <traffic-
class> ]
Where the parameters are defined as follows:
• [<number>] optional parameter which indicates how many pings are sent
• [timeout <seconds>] optional parameter which indicates the time-out period of the ping
• [packet-size <packet-size>] optional parameter which indicates the number of octets in the ping
• [ttl <ttl>] optional parameter which indicates the time-to-live value
