Having issues with the line-rate with SDSL router 878. Everytime i reboot the router the line-rate seems to change which casues it to loss internet connectivity. In order to restore internet connectivity you need to manually configure the line-rate. Has anyone had this problem or assist me with resolving this problem

Hi, according to:

http://cisco.com/en/US/prod/collateral/routers/ps221/prod_bulletin0900aecd801d5c4c.html


If you upgrade to 12.4(6)T, that would give you 3.05 firmware, chances are it will solve your problem.


Hope this helps, please rate post if it does!

Hi,


please send output of "show dsl interface". You might need a DSL firmware upgrade.
