Bandwidth limitation for Cisco routers

Hello All,

I’m just wondering Cisco recommends a specific router based on the bandwidth requirements as we’re having 2611 router with 64 DRAM and 8 Flash, currently is handling 3 Mb of internet bandwidth and we’re planning to upgrade to 5 Mb, I want to know the recommended bandwidth that can be handled by this router.

Your help is highly appreciated...

Re: Bandwidth limitation for Cisco routers

Hi,

As such cisco doesnot recommend routers based on bandwidth. You have to see your traffic pattern and the link and routers CPU utilization depending on the different types of applications you are running.If router has to process the traffic more than it can, you will see some application related issues.That's when you can go for a router with higher CPU power.

We have few 2600's with around 10 MB link on those.Link utilization is arnd 40% on all of them. it works OK.

If with the increase of the bandwitdh you ahve some more routes added to the routing table, then you migh also check for your DRAM.Make sure that DRAM supports the large routing table and other routes as well.

Use two commands in IOS to check it:

show process cpu

show process memory

HTH,
