Solved: 2801 - Max Ethernet Speed

snooter · ‎06-24-2011

We have a 2801 rotuer in place that hooks up to a metro ethernet link that's obviously dropped off to us via ethernet. Anyway, the throughput granted to us is 20MB, but for some reason I can't get it to go anything above 11MB at the most. I've spent a day going through documentation trying to find the fastest speed the 2801 supports and I can't find my answer. I've seen that the high speed wan cards in this router support up to 45MB, but I'm not using a WAN card, only one of the two built in 10/100 ports.

Anyone able to lend me some information here on what the maximum throughput speed is on a 2801?

Also, there is no traffic shaping in place on our equipment on either end. It's wide open.

snooter,

Good morning

The 2801 Router is not a small business class router and we have moved your discussion to this area:

I hope you have a great day

Thank you Joesph. Exactly what I was looking for.

So, given my running config above, I'm assuming the issue has to be outside of my 2801. I should easly be able to get 20MB through the 2801.

Check show interfaces for drops and other anomalies.

Also need to know how are you measuring the performance limitation.

Keep in mind when you look at the performance charts you often need to allow for duplex (i.e. forwarding in both directions) and you need to allows for services.

A quick test whether this router's performance capabilities is the bottleneck, check CPU load when it hits your 11 Mbps. If the router isn't near 100%, then router's forwarding capacity likely isn't the culprit. That doesn't exclude the router itself from being the culprit, which is partially why Paolo is asking for the information he does.
