Hi All,
If you were wating to see how much traffic/congestion was on your enterprise (L3) LAN backbone what are some good ways to do this. I know you can use the usual tools like wireshark, solarwinds, etc... Just curious as some methods used.
Thanks,

Hello Brandon,
you can have nice graphs of MIB variables like ifinoctets ifoutctets drawn by MRTG with a reference line = link speed
it provides graphs in a daily, weekly, mounthly basis so it gives both a baseline and growth trends
see
So you can trace link usages on all devices and navigate on web pages
Hope to help

Hi Giuseppe,
Thanks for the info. Is this program similar or the same as "Cacti"? I have that in place.
Thanks,

Hello Brandon,
I think they are similar
both use the
RRDTool's data storage and graphing functionality.
So by having a look at the graphs you could have a vision of link usage over time.
Probably you can also try to create events on devices that send traps when link usage is above a threshold.
This can be a different approach with devices playing an active role but requires additional configuration.
see for example EEM embedded event manager
Hope to help
