.Sh SYNOPSIS
.Nm

.Ar path command
.Sh DESCRIPTION
The
.Nm
utility is intended to control the
.Xr ng_netflow 4

.It Fl d Ar level

.Sh COMMANDS
Currently,
.Nm
supports only one command.
.Bl -tag -width ".Cm show"
.It Cm show Op Cm ipv4|ipv6
This command is the analog of the
.Dq "show ip cache flow"
command of a Cisco router.
It dumps the contents of the flow cache in Cisco-like format.
Specifying either
.Cm ipv4
or
.Cm ipv6
would extract only IPv4 or IPv6 flows respectively.
It has optional parameter
.Cm verbose ,
which is analog of the
.Dq "show ip cache verbose flow"
command.
