How can I monitor traffic in/out of Cisco 3750 switch??

I have found alot of MIB's on cisco's ftp site but there are not descriptions of what exactly each MIB is used for.  Can anyone tell me what MIB I need to accomplish traffic monitoring on my Cisco 3750 switch?  Thanks

Depends on what application you are using. The web-based utilities within the switch itself are the best I've seen.
Using the web GUI, you can see a picture of the switch front panel, right-click any port and monitor real-time traffic statistics.

There are several packages on the market that can monitor a 3750.  Have you looked at MRTG?  (

It has the cfgmaker package that should walk the switch and let you know what it can see...

MIB wise, I thought the 3750 is supported natively with the "standard" MIB's.  We use JFFNMS for monitoring here which is based on RRDtool and it has no problems pulling temperature, throughput, port status etc. from 3750's....


Did you see on the FTP site, this is still a supported MIB.
