The monitor atm vc command and monitor atm vp command display similar
information, except that the monitor atm vc command displays the VCD for
each interface and the monitor atm vp command displays the VPI for each
interface.
The router polls the statistics of each VC or VP identified in the command at the
specified load interval to calculate and display bit rate and packet rate statistics.
The first line of output for each interface always displays 0 (zero) for the number
of seconds between polls, and dashes (--/--) in the Input bps/pps and Output
bps/pps columns. These values indicate that the router initially takes a baseline
for each interface against which to measure subsequent statistics. The router
continues to display subsequent lines of output for each interface at the specified
load interval until you press Ctrl+c to stop the command.
For a description of the fields in the command display, see "monitor atm vc" on
page 72 and "monitor atm vp" on page 72.
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.
