Using the monitor interface Command
Use the CLI
monitor interface
command to display real-time traffic, error, alarm, and
filter statistics about a physical or logical interface. Enter the command with the
following syntax:
user@host> monitor interface (interface-name | traffic)
Replace
interface-name
with the name of a physical or logical interface. If you specify
the
traffic
option, statistics for all active interfaces are displayed.
The real-time statistics are updated every second. The
Current delta
and
Delta
columns
display the amount the statistics counters have changed since the
monitor interface
command was entered or since you cleared the delta counters. Table 127 on page
245 and Table 128 on page 245 list the keys you use to control the display using the
interface-name
and
traffic
options. (The keys are not case sensitive.)
