Troubleshooting
This test sequence requires that the switch fabric be configured with a valid
PVC and the endstations to have the proper IP configuration and ATM ARP
cache entries. The tests in Figure A.3 assume that there is no IP connectivity
between the two endstations. The lack of an IP connection is checked by try-
ing a ping and getting no response (ping failed).
The tests in Figure A.3 also require that if a switch fabric is used, it is a
Cabletron Systems switch fabric on which SPANS has been disabled on both
the ports of the switch fabric and on the ATM endstations. SPANS must be
disabled because it automatically creates ATM connections, which may alter
the test results.
All of the failure conditions are the result of running a continuous ping with
the following command:
ping <IP_address_of_remote_workstation>
