Hi,
I have seen alarms within monitoring system that my primary circuit went down. During that time, no alarms on the back-up appears in monitoring system, however we did not have service in the office. We believe traffic did not switch to back up although this one was working.
When primary is down and backup is up; what are the reasons for traffic not have switched ? Something related to HSRP or any other?
Thanks a lot in advance for your response,
Have a nice day
TP
