Cayman 3220-H User’s Guide Using the Command Line Interface

December 2000 4-5

ROOT Command

Shortcuts

You can truncate most commands in the CLI to their shortest unique

string. For example, you can use the truncated command q in place

of the full quit command to exit the CLI. However, you would need

to enter rese for the reset command, since the ﬁrst characters of

reset are common to the restart command.

The only command you cannot truncate is restart. To prevent

accidental interruption of communications, you must enter the

restart command in its entirety.

You can use the Up and Down arrow keys to scroll backward and

forward through recent commands you have entered. Alternatively,

you can use the !! command to repeat the last command you

entered.

ROOT Commands arp nnn.nnn.nnn.nnn

Sends an Address Resolution Protocol (ARP) request to match the

nnn.nnn.nnn.nnn IP address to an Ethernet hardware address.

atmping vpi vci [ segment | end-to-end ]

Lets you check ATM connection reachability and network

connectivity. The atmping command sends ﬁve OAM (operation,

administration, and maintenance) loopback cells to the speciﬁed

VPI/VCI destination.

Use the segment argument to ping a neighbor switch. Use the

end-to-end argument to ping a remote end node.

clear [yes]

Clears the conﬁguration settings in a Cayman 3220-H. If you do not

use the optional yes qualiﬁer, you are prompted to conﬁrm the

clear command.
