I recently replaced our firewall and immediately ran into problems with our cameras. Most of them stopped working and I couldn't access the camera server from our PCs using the VIGIL app, which is supposed to stream live footage. The only cameras that are still functional are those connected directly to our core switches. Any cameras hooked up to one of our three intermediate distribution frames (IDFs) are completely non-functional.
I figured out the issue regarding the camera server access — it turned out to be an oversight with the trunk ports on the core stack; I had to add the camera VLAN (VLAN 20) to the allowed list. That fixed that part of the issue, but I'm still struggling with the cameras in the IDFs. I've detailed my network setup and the steps I've taken so far to troubleshoot the problem, hoping someone might have suggestions, even if they're long shots!

Make sure VLAN 20 is actually active on your core switches. Sometimes, even if it's configured, it can end up not being recognized properly. Use the command `show vlan brief` to confirm it shows as active. And remember, if the VLAN isn’t on the list, the traffic won't pass through, even if ports are set up correctly.
It sounds like you've done plenty of troubleshooting already! From your tests, it seems like a trunking issue might be at play, especially since you can't ping the camera server from the IDF. Double-check that all the uplinks between the IDFs are set correctly as trunk ports and that VLAN 20 is tagged appropriately on both ends. That could be the hiccup.
Yes, I checked that! VLAN 20 is definitely active on the core. It shows up when I run the command.
