Broadband Max service on a cisco 837

Can you post the results of a 'sh dsl int atm0'?

Chris.

Hi Jon,

You may wish to investigate Cisco ADSL configuration wizards:

Hope this helps.

Brad Reese on Cisco Network World Magazine Cisco Subnet

Well, you've trained up at a good speed and there's no errors. You shouldn't be having any issues at all.

Chris.

That looks OK compared with what I see.

It says that the downstream rate is 7616 kbps and the upstream is 800k.

There have been a fer Error Correction events and maybe a few Error Corerction failures (CRC and Header errors)

The issue does not appear to be with the raw ADSL speed negotiated.

Maybe the router is running out of CPU?

The easiest thing is if you post the whole config.

Remove passwords, user names, change real ip addresses (in such a way that the config can be understood).

Also change the config as fiollows

int dialer x ! whatever you use load-interval 30

re-run the test and post

sh proc cpu ! first line only sh int dialer x When the download test has been running for a bit but has not yet stopped.

Check that you are not getting packet fragmentation

sh ip traffic

That looks ideal. Could hardly be simpler. Key thing is fast switching is not disabled "no ip route cache".

Hi,

RE: int dialer1 load-interval 30

Adding this command made the speed even slower.

Results from other commands are;
