Viewing The Backup Ppp Interface; Monitoring The Dial-Up Process - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

Viewing Backup Configurations and Troubleshooting Backup Connections
Backup phone number list—This is the backup dial list, which includes:
• Number—the peer's phone number
• Call type—analog, digital 56K, or digital 64K
• Min/max DS0s—for ISDN lines only; the setting should read "1 2" for
bonded lines
• Backup I/F—the PPP interface that manages the backup connection
You cannot view a logical interface's settings for persistent backup in the usual
status report generated with the show interfaces command. You must enter
show backup interfaces. The show backup interfaces command does not
show backup PPP interfaces (which you view with the typical show inter-
faces ppp <interface number> command). Rather, it shows backup settings
for primary logical interfaces.

Viewing the Backup PPP Interface

You can use the show interfaces command to view the IP address on the PPP
interface for the persistent backup connection. However, this command will
not show you all the authentication configurations. You should instead exam-
ine the running-config for the backup interface. For example:
ProCurve# show run int ppp 2

Monitoring the Dial-Up Process

Monitoring the dial-up process can help you discover why a backup connec-
tion does not come up when the primary connection fails. Use the debug
commands to receive real-time messages about backup link negotiation:
ProCurve# debug backup
ProCurve# debug dialup-interfaces
The CLI displays backup messages received on both the dial-up and the logical
interfaces. Messages appear marked with the date, time, type of event, and
associated interface. For example:
2003.08.13 02:55:31 DIAL_BACKUP.bri 1/3
