Specify the interface identifier and VCD (for each ATM VC) or VPI (for each ATM
3.
VP) that you want to monitor. For information about specifying an ATM interface,
see Interface Types and Specifiers in JunosE Command Reference Guide.
host1#monitor atm vc atm 12/0 1 atm 8/0 1 display-time-of-day
host1#monitor atm vp atm 12/0 0 atm 12/0 1 load-interval 15 display-time-of-day
By default, the router uses a 5-second time interval between polls to calculate bit
rates and packet rates for each specified VC or VP. Optionally, you can use the
load-interval keyword to specify a nondefault time interval in the range 5–30 seconds
(for ATM VCs) or 5–300 seconds (for ATM VPs).
You can also include the optional display-time-of-day keyword to show the time
of day at which the router gathers statistics for each interval. Displaying the time of
day enables you to monitor when a particular VC or VP is underutilized or overutilized.
Review the command output.

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.
