Cabletron Systems 9A000 manual ping IPaddressofremoteworkstation, A-10, Troubleshooting

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>

A-10
