All, I have a remote location that uses SWB DSL connection. After hours, the 1750's E0 interface stops responding to ping. I have tried keepalives and have had the same problem. I have called the ISP three times and they can find no problem. Last night, the router was bouncing up and down 10 times. PLease help.
Thanks

Any good logs from the router? How about errors in 'show interface eth0' or 'show controller eth0'?

Show log on the router does it show that the E0 went down? Maybe the problem is not an interface problem. It can be some other thing such as IP conflict on E0 interface.
Let me know,

Also, look at sh ver -- it will give router uptime and the reason for the last reboot. Insure the router is staying up (or if it goes down, read the reason why).

Logging is disabled on your router. Enable logging so you can track what's going on the router. Use the command "logging buffered"
Let me know the logs after some days,

Can I just do a show log to view the logs?
