Allied Telesis at-8700xl series switch Resetting Switch Defaults, Checking Connections Using PING

Maintenance and Troubleshooting 79

Resetting Switch Defaults

To restart the switch at any time with no configuration, enter the command:

RESTART SWITCH CONFIG=NONE

If boot.cfg has changed, to set it back to the default configuration by saving the default dynamic configuration to the boot.cfg file, enter the command:

CREATE CONFIG=boot.cfg

To set the switch to restart with the boot configuration file, enter the command:

SET CONFIG=boot.cfg

DO NOT clear the FLASH memory completely. The software release files are stored in FLASH, and clearing it would leave no software to run the switch.

Checking Connections Using PING

If an aspect of the switch’s configuration dependent on access to a server functions incorrectly, PINGing the server from the switch, and the switch from the server, is a useful first step in diagnosis.

You can use PING (Packet Internet Groper) to check whether there is a connection between the switch and another routing interface in the network. Use the switch’s extended PING command over IPv4, IPv6, IPX and AppleTalk network protocols. PING sends echo request packets in the chosen format, and displays responses at the terminal. Enter the command:

PING [{[IPADDRESS=]ipadd[IPXADDRESS=]network:station [APPLEADDRESS=]network.node}] [LENGTH=number] [NUMBER={numberCONTINUOUS}] [PATTERN=hexnum] [{SIPADDRESS=ipaddSIPXADDRESS=network:station SAPPLEADDRESS=network.node}] [SCREENOUTPUT={YESNO}] [TIMEOUT=number] [TOS=number]

To set PING defaults, enter the command:

SET PING [{[IPADDRESS=]ipadd[IPXADDRESS=]network:station [APPLEADDRESS=]network.node}] [LENGTH=number] [NUMBER={numberCONTINUOUS}] [PATTERN=hexnum] [{SIPADDRESS=ipaddSIPXADDRESS=network:stationSAPPLEADDR ESS=network.node}] [SCREENOUTPUT={YESNO}] [TIMEOUT=number] [TOS=number]

To display the default PING settings and summary information, enter the command:

SHOW PING

The stop a PING that is in progress, enter the command:

STOP PING

If you can PING the end destination, then the physical and layer 2 links are functioning, and any difficulties are in the network or higher layers.
