Hi all,
Wondering if anyone has come across this issue and what steps you took to fix it. Periodically groups of Cisco devices (Mostly 3700 series and ASA series) in our remote offices will all report as down down all with 100% packet loss. I know that this cannot be true as I can still ping these devices, and have been in communication with the local admins who have told me on each occasion that there is nothing wrong with that set of devices.
I have also experimented in changing the polling rate, in case there were any latency issues causing the packets to not be delivered.
I assume then, that there is some issue with our firewall blocking the polling traffic. I do not have experience working with firewalls, so I'm unsure really where to start trouble shooting this.
Basically I want to know whether anyone has had a similar issue, steps they took to resolve it, and whether or not I'm on the right track with the troubleshooting process.
I appreciate any help you'd be willing to contribute and will provide any necessary info to help troubleshoot.
Thanks!
