Hi All,

I have a cisco catalyst 2801 and a cisco catalyst 3750. I want to have a monitoring of the performance of this network devices especially the cisco 2801 as well as to have graph of its bandwidth utilization and which ip address is eating the most bandwidth. this is to help me analys what may be the problem when our network slows down.

Can anyone here help me how to configure this 2801 to have that or is there any freeware software from cisco that can do what i want?

any help would be grately appreciated

thanks,

nhel

Take a look at this:

http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6555/ps6601/prod_white_paper0900aecd80406232.html

There is a compatibility matrix, tools, freeware all explained in the above document.

Hope you have linux skills

Also for monitoring bandwidth use Cacti (MRTG,RRD). Again, linux is your friend. Or for a price I can do it

HTH,

Ian

Here's a good free Windows Netflow collector-

It's real-time only though.

I was looking at this a couple of months ago. My end result is to configure Nbar on the links use ip nbar protrocol discovery command. Then once I see what is going on you start using QoS to give priority of drop what you wish. For the graphing I purchased the PRTG network monitor program. But I also manage in excess of 200 devices from routers, to controllers, to access points. You can try it free for 30 days.

PRTG is just a Windows based MRTG with Cacti like front-end. You can do it all for free on Linux. If your going to pay you could consider PRTG or Solarwinds / Orion Network Performance. There are loads of others on the market. But directors like FREE. (except for the cost of the server of course although it can be any PC with linix on and PC's are not expensive these days).
