A remote office keeps complaining that they are losing their internet access. I never seem to be able to catch the problem whilst it's happening, so I was wondering if I can setup their cisco 877 to log when the internet connection drops. Can anyone tell be what I need to do to set this up?
Logging on Cisco routers can be in one of these 4 methods:
1.The console by default ("logging console" under the global configuration) - The logging will pop-up to the terminal when you are connected via console.
2.The current terminal line (to the vty sessions when "terminal monitor" is enabled - to disable use "terminal no monitor" - Exec mode not configuration mode) - pop-up logging on you screen like in the first method but it is not enabled by default (needs the "terminal monitor").
3.The router internal logging buffer (use "logging buffered" then "show logging" to display the logs saved in the logging buffer (router internal buffer), but the main drawbacks here is the limited size of the buffer and that the log is lost if the router reloads).
4.The syslog server (use "logging ") the most preferred method, its only drawback is when the connectivity is lost with the syslog server.
I always use a combination of all these methods according to the case.
I hope that i've been informative.
