Hello,
We have three 3300 controllers that are connected to each other via a cisco switch. We have no IP phones, just analog and digital.
Last week, we were testing emergency power. When the power was cut, the cisco switch went down (severing the connection between the 3 controllers) but the controllers switched to UPS. When power was restored, the switch came back and the connections were restored. Unfortunately, controller 2 did not work correctly and most calls were failing. After viewing the log, I saw that I was getting a lot of packet loss entries like the one below.
Example: E2tSp - IP Network Dropped 3.94 percent of Packets from phone xxx.xxx.xxx.xxx Total Rx: 268 Lost=11......
Because lines were basically down on that controller, I rebooted the controller and the packet loss stopped and everything returned to normal.
Now, fast forward to yesterday where we performed another emergency power test. Again the switch went down and the 3 controllers went to UPS. Power was restored and everything went back to normal. I checked controller 2 and it also seems to be normal. However, this time, controller 3 is spewing out these same packet loss messages.
I have checked with users who have phones on controller 3 and no one is noticing any issues. I don't want to reboot the controller and bring the phones down (which worked for controller 2) if they are working but the stream of IP Packet loss alerts in the log is constant.
Can anyone think of another way to possibly alleviate this without rebooting the controller?
Thanks a lot for your time!
