Phase 3: Problems on ATM Media Ports Without
ATM Traffic
The problems in this phase occur after the status of all ATM media ports is NO ACTIVITY
and ATM devices have been attached to ATM media ports. No ATM traffic is started in
the hub.
Phase 3 problems occur because one or more ATM media ports are not functioning
properly. The aim of the troubleshooting operations in this phase is to:
Change the status of all ATM media ports to OKAY (as shown with the SHOW PORT
command) so that ATM traffic can be started in the hub.
Correct errors in ATM address registration between ATM media ports and attached
ATM devices, unless a device is operating in PVC mode.
Phase 3 problems are divided as follows:
Problems concerning ATM media ports that are attached to ATM devices
Problems with ATM address registration
Problems concerning the hardware environment.
If you cannot solve the problem and if ATM media port status does not change to OKAY,
contact an 3Com service representative before starting ATM traffic.
