To monitor the data rate for ATM VPs, use the monitor atm vp command.
To monitor the data rate for ATM VCs and ATM VPs:
1.
Log in to the router by using a local console session or a virtual terminal (vty)
session (such as a Telnet session).
While you use the monitor atm vc command or the monitor atm vp command,
you must keep the console or terminal session open. You cannot issue any other
commands during the session.
For information about logging in to the router, see section Accessing the CLI in
JUNOSe System Basics Configuration Guide .
2.
Access User Exec mode or Privileged Exec mode.
For information, see section Accessing Command Modes in JUNOSe System Basics
Configuration Guide .
3.
Specify the interface identifier and VCD (for each ATM VC) or VPI (for each ATM
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.
4.
Review the command output.
