Cumulative Jitter for a Probe
The Services Router maintains records of the most
recent 50 probes for each configured test. These 50
probes are used to generate RPM statistics for a
particular test.

Monitoring PPP
PPP monitoring information includes PPP address pool information, session status
for PPP interfaces, cumulative statistics for all PPP interfaces, and a summary of PPP
sessions.
NOTE: PPP monitoring information is available only in the CLI. The J-Web interface
does not include pages for displaying PPP monitoring information.
To display PPP monitoring information, enter the following CLI commands:
■
show ppp address-pool pool-name
■
show ppp interface interface-name
■
show ppp statistics
■
show ppp summary
