I have a topology as follows.
I have one central router and many branches connecting to it through ethernet ,serial media.
I am looking for a way to report the link changes during a period and the list of events when a particular branch went down.and the percentage of total time it was offline.Can i get some graphical chart for that.Also is there a possibility for the administrator to comment on event.
is the above possible through cisco netmanger. How can i do it
Or there is some other tool available for this.
