I looked at the screenshots and I think I see the configuration problem. Ports 49 & 50 are your fiber trunks. They're correctly set to trunk, but they're not tagged. When access ports are set to untagged and PVID is set. That means packets coming in from the access devices won't have tags, but they are assigned a tag when you have port based vlans configured. So all the packets from the cameras get assigned a VLAN 20 tag before they're sent out across the trunk. Ports 49 & 50 aren't set to tagged. so when tagged packets from the access ports reach the trunk ports, they just drop the packets. If you have 1 vlan traversing the trunk such as the mngmt vlan 1, you don't have to set the trunk to tagged and ust checking Port based Vlan ID (PVID) gets the packets across the trunk. Therefore, on both trunk ports 49 & 50 on both switches you need to set them to tagged so they'll carry traffic across those trunks in both directions between both switches. That should do the trick. _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
