throughput issues..

Patrick Evans
Level 1
Level 1

Hi Guys, 

I am curreltly studying for my CCNA and although I believe I have everything set up more or less correctly, My network throughput out to the internet is Very slow (0.06mbps) when running through my test network.  Directly through my home gateway is around 59mbps for example.  Can anyone see a reason why in my config below? Also,  please can someon tell me how to embed my config in a window rather than pasting it? I have seen people on here doing it an it looks a lot neater.  Thanks in advance for any help that you can offer.

I see several things that would explain the slower performance when going through these routers.

- the router to router link is a 64K serial link. If the traffic goes over this link then 64 K is the absolute fastest throughput you will get and realistically it would be slower than that.

- on router 1 the Ethernet interface is set for half duplex. This will also slow down performance.

- on the serial interface of router 1 you have used the network address as the interface address.

Thanks for your reply Richard, 

It is going through the serial link so that is my problem.  I can change that up to 115200 can I?

I have now set the f0/0 int to full duplex,  I think it was on auto before. 

On your last point I thought that I could use the .0 as it was a /31 network for a point to point link. I read about it here : http://tools.ietf.org/html/rfc3021 Or have I mis-understood?

Thanks again for your help. 

Patrick

Patrick

Setting the duplex to auto should be fine, or setting it to full will force it. Unless there is some reason to need half duplex you should not configure this.

What speeds are possible on the serial interface depends on what type of card is installed.

My apologies for mis-reading (or not paying sufficient attention) to the mask used with the address. As a /31 the .0 should be ok.
