Cisco 877 View Line stats

[mike1210]

Hi,
Ive had this router for a few months but im too familiar with ths IOS (doing ccna in september). Does anyone know the commands to view line stats (signal to noise ratio etc) and change the MTU on the dialer to 1458. Will the line stats show wheather interleaving is switched on. Im on MAX DSL and was getting 6 meg late in the nignt which has now dropped to 2.5

using ios 12.4.6 and sdm 2.3. 877W model

sh dsl int atm 0

On the atm interface....

ip mtu xxxx

That will do the job

I assume this means i have been put on interleaved??? my line speed was fine i always got 6 meg at off peak times and the router never died or lost connection

Yes you are on the interleaved path.

thanks for this one last question how do i get to the atm interface via commands for the mtu, sorry dont know the ios at all

You'll need to change it on any machines connected to as well remember...
