For a description of the fields in the command display, see "monitor atm vc" on
page 69 and "monitor atm vp" on page 69.
If you remove an ATM interface or (for VCs) an ATM 1483 subinterface while you are

monitoring one or more VCs or VPs that reside on the deleted interface, press Ctrl+c
to stop the monitor atm vc command or monitor atm vp command, and then restart
the command to ensure accurate interface rate statistics are displayed.
If you leave the monitor atm vc command or monitor atm vp command running
after you remove the interface, the command displays undefined or inaccurate
statistics for the VC or VP on the interface that has been removed. The display of
undefined or inaccurate statistics can result when you remove the interface by issuing
either the no interface atm command or slot erase command, and can continue
even after you recreate the interface with the same VC or VP configuration.
When you are finished monitoring, press Ctrl+c to stop the monitor atm vc command

or monitor atm vp command.

Use the monitor atm vc command to display bit rate and packet rate statistics over a
specified time interval for one or more ATM VCs.
Use the monitor atm vp command to display bit rate and packet rate statistics over
a specified time interval for one or more ATM VPs.
You must use either command in a dedicated console or terminal session for the
duration of the monitoring session.
Specify the interface identifier and VCD (for each ATM VC) or VPI (for each ATM VP)
that you want to monitor.
To specify a nondefault time interval in the range 5–30 seconds (for ATM VCs) or
5–300 seconds (for ATM VPs) at which the router calculates bit rate and packet rate
statistics, use the optional load-interval keyword. The default time interval for either
command is 5 seconds.
To display the time at which the router calculates bit rate and packet rate statistics
for the current interval, use the optional display-time-of-day keyword.
To stop either command, press Ctrl+c.
