ATM Debug Commands
atom findPVC <on | off>
Shows VPI*VCI of cells received. This command is normally used to find the ATM VPI*VCI number
necessary for configuring a remote when the Service Provider either has supplied the wrong value or simply
is not able to supply one.This command should only be used when there are no remotes defined or when the
remote entries are disabled.
The command output is directed to the console. If Telnet is used to log into the router, then issue the system
log start command to direct the console output to the Telnet session.
Example:
# atom findPVC on
No remote entry found with PVC (VPI*VCI) 1*2
In this case, an ATM VPI*VCI is found for which there is no remote defined. 1 is the number of the VPI as
found in the ATM stream. 2 is the number of the VCI as found in the ATM stream. The discovered number
may be used as the VPI*VCI value in the remote, for determining whether communications are possible.
atom echoPVC <vpi number>*<vci number>
Enables an echo pvc (use atom echo 0*21). This is configured automatically and can be disabled with atom
echo 0*0. The echoPVC will echo back any ATM cell received on the PVC exactly as received. This is useful
when an administrative service wishes to ensure ATM connectivity but cannot use ATM OAM F5 cells to
achieve this function.
atom pls <on | off>
Changes payload scrambling.
atom empty <ATMF | ITU>
Changes type of ATM empty cell sent or expected. It is useful if ATM sync delination errors when combined
with ato stats command.
atom dumpunknowncells [on | off]
Looks at the content of an ATM cell. It will not affect normal operation performance.
Web GUI Debug Commands
Using a browser pointed to the router, you can display special pages in the web GUI, such as, 192.18.254.254/
time.htm.
time.htm Displays time.
quick.htm Displays all Easy Setup parameters.
