Pulling bandwidth data via SNMP

I would like to check the bandwidth statistics (latency, kb/s, # of packets...) on my routers' serial and ethernet interfaces. I figure I need some kind of SNMP software and some configuration changes to my routers but I don't know where to start. Can somebody point me in the right direction?

Thanks,

Diego

Re: Pulling bandwidth data via SNMP

http://www.cisco.com/warp/public/477/SNMP/calculate_bandwidth_snmp.html is a good tech tip on this for a start. MRTG is a free ware which you can also look at (http://www.mrtg.org). If you want to dive into more depth, then the book, 'Performance and Fault Management' by Cisco Press is also a very good reference.

Re: Pulling bandwidth data via SNMP

Comstor UK are working with an Irish software house who can assist in some way with their NetFlow Monitor product. You will need to enable Netflow on your router:-

IOS Commands

Configuration:

ip flow-export destination 10.1.1.1 2055

ip flow-export version 5

ip flow-export source loopback 0

ip flow-cache timeout active 4 (mins)

ip flow-cache timeout inactive 30 (secs)

int s...

ip route-cache flow (put on all WAN and LAN interfaces)

Diagnostic:

Show ip flow export

Show ip cache flow

then obtain an evaluation copy of "NetFlow Monitor" from www.crannog-software.com

contact uksales@crannog-software.com for further details.

Regards,

Campbell.

Re: Pulling bandwidth data via SNMP

You could try JFFNMS an OpenSource Network management system, which includes Bandwidth monitoring and interface autodiscovery and is focused on Cisco Equipment.

It runs on Windows also (prefered is Unix).

You can get reports on the dates you specify, with RTT, PL, Input Rate, Input Packets, Drops, Availability, etc.

The URL is http://jffnms.sourceforge.net

Re: Pulling bandwidth data via SNMP

If you already have OpenView or NetView, all you need to do is enable it and add a few things. You can graph and keep history, whatever you want. This is for ALL snmp devices. dkontner@nisource.com.
