Display the network traffic going through active interfaces on the

Idle interfaces will not be displayed until they receive some

|

.Pp
|

For each interface being displayed, the current, peak and total
|
||||
statistics are displayed for incoming and outgoing traffic.
|
||||
By default,
|
||||
the
|
||||
.Ic ifstat
|
||||
display will automatically scale the units being used so that they are
|
||||
in a human-readable format.
|
||||
The scaling units used for the current and

peak
|
||||
traffic columns can be altered by the
|
||||
.Ic scale

command.

.It Cm match Op Ar patterns
|

Display only interfaces that match pattern provided as an argument.
|

Patterns should be in shell syntax separated by whitespaces or commas.
|

If this command is called without arguments then all interfaces are displayed.
|
||||
For example:
|
||||
.Pp
|
||||
.Dl match re0, bge1
|
||||
.Pp
|

This will display re0 and bge1 interfaces.
|

|
||||
.Dl match re*, bge*, lo0
|

.Pp
|

This will display all
