I work for ISP so they probably have all the logging turned on. That is something that would be good addition to this website. using the show log command on cisco to find logs.
I know how to do it pretty decently on a Juniper just because I was shown in the last week and I have to use it a lot. We also have Cisco equipment but I have not worked as much with that yet as they start us out on the Juniper as its much easier to work with. I also hear Alcatel is easy but have not gotten to work with that much yet.
On side note I did login to ASR 9000 Series Cisco Router and it actually had the “last flap” Most of the other cisco though I have seen have been smaller devices and did not.
