Hi I am using freebsd 4.9 with ipfw to shape b/w for my broadband clients.
I have created a 64Kbit pipe and I have configured few ips to use the pipe. ie
more than one client share the same 64Kbit pipe.
I have been montoring the b/w utilization by using the command:
ipfw pipe show $inpipe | tail -1 | awk '{ print $6 }
ipfw pipe show $outpipe | tail -1 | awk '{ print $6 }
This is the output of ipfw pipe show $pipe_no
BKT Prot _Source IP/port_ __Dest. IP/port___ Tot_pkt/bytes Pkt/Byte Drp
0 tcp 24.76.245.191/62165 202.79.50.55/4347 2826105 864936484 42 11232
150386
I assumed the 6th field gives the total bytes going though the pipe.
These two commands give the bytes going through the pipe and I am using the
values to plot the mrtg graph.
But I see b/w utilization exceeding 64Kbit. At one point it reached 93Kbit!!
Am I using wrong countres to obtain b/w utilization?? please aadvice.
with regards,
Bikrant
