Displaying And Maintaining Atm Interfaces; Troubleshooting Atm Interfaces - HP HSR6800 Configuration Manual

Step
7. Set the loopback mode.
8. Set the intended bandwidth
for the ATM OC-3c/STM- 1
interface.
9. Restore the default settings for
the ATM OC-3c/STM- 1
interface.

Displaying and maintaining ATM interfaces

Task
Display information about a
specified or all ATM interfaces.
Clear the statistics on all PVCs on a
specified ATM interface.
Clear the statistics on an ATM
interface.
NOTE:
For those physical interfaces that are not connected to cables, shut down them using the shutdown
command to avoid anomalies resulted from interference.

Troubleshooting ATM interfaces

When diagnosing ATM interface problems, first test the interface with the ping command or the
extended ping command.
The ping command can test network connectivity. Extended ping command can be used to specify some
options in the IP header in addition to that function. For more information about the ping command, see
Network Management and Monitoring Configuration Guide.
If the interface cannot be pinged, check whether:
• The interface is down, which causes missing of its route in the routing table.
The AAL5 encapsulation of the PVC is incorrect (for 155 Mbps ATM interfaces only).
