Dear all,

I want to monitor the bandwidth utilization of a internet link connected to cisco router. Is there any tool available.

Please help me.


Thanks
Shan

The router should have snmp support. Therefore a snmp bandwidth monitor should probably do. Note there may be other (read better) ways to do what you want.

Here are some free tools I found:
for linux ->
http://rtg.sourceforge.net/

for windows->

Hope this helps. Cheers

Thanks for your reply.

I enabled snmp on cisco router for monitoring.
is there any tool to monitor the router interface traffic on IP level. I want to know which ip address utilized which amount of bandwidth


Thanks in advance,
Shan

SNMP is not the best tool to get this information. There are two things you can do.

1. Enable IP accounting on the interface. Then show ip accounting on the cli will tell you what IP has sent how much data.

2. For port level detail, configure netflow on the interface using "ip route cache flow". You can then look at the netflow stats using "show ip cache flow".

Better still you can export netflow data to a netflow collector, which can then produce all sorts of lovely graphs for you.

I would recommend ntop as a netflow collector.
