The router polls each VLAN subinterface at the specified load interval (the default
5-second interval in this example) 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 each field in the monitor vlan interface command output,
see "monitor vlan interface" on page 190.
When you are finished, press Ctrl+c to stop the monitor vlan interface
command.

Use to display bit rate and packet rate statistics over a specified time interval for
one or more VLAN subinterfaces.
You must use the monitor vlan interface command in a dedicated console or
terminal session for the duration of the monitoring session.
Specify the interface identifier for each VLAN subinterface that you want to
monitor.
To specify a nondefault time interval in the range 5–30 seconds at which the
router calculates bit rate and packet rate statistics, use the optional load-interval
keyword. The default time interval 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 the monitor vlan interface command, press Ctrl+c.
