Before, the issue we were having with our current network was that the IE-4000, which is the main node at each site could see the Cambium 450M APs and 450I subscribers, but were unable to see the IE-3300 switches at the remote ends of the links. We thought this was a spanning-tree related issue due to the cnMatrix we were using to power the APs having a hard limit of 32 VLANs with rapid-PVST.
After bypassing the cnMatrix, each AP is connected directly to a trunk port that allows all VLAN traffic through, and while the show LLDP Neighbors command shows that the APs are connected to the IE-4000 switch, and the show CDP Neighbors command shows the switches on the far end, we have no network connectivity, seeing as we cannot ping the APs or anything further downstream from the IE-4000 switch when the ports that are connecting to the APs are configured as trunk ports.
When we set them to access ports, we are able to see the AP, the subscribers connected to the AP, and the remote switch. But we need them to be trunk ports because we have multiple VLANs on each of the remote switches that need to be able to pass their traffic through.
The topology is also designed as such,IE-4000-->450M-->450i-->IE-3300
Edit: The AP and subscriber are both on VLAN 5 as well.
I have been advised that configuring the trunk ports with the native vlan 5 command would help, but upon trying it, the issue still persisted. At this point, the only thing I can honestly think that is causing this issue would be a problem with the routing.
Should I add a no passive-interface command on the trunk ports and the management vlan or would that even do anything?
Here are the relevant VLANs, port and routing configurations for the IE-4000 switch.
