At my office I have two switches. SW-1 (HP-V1910-48G) is the switch my desktops are connected to, and SW-2 (HPE-1920 JG927A) is where my server rack with my dhcp and default gateway is connected. Recently i've been trying to bring some cameras onto the network under VLAN 10. All of the other traffic on the network is on VLAN 1. One problem I have been facing is that SW-2 can talk to the server rack and any devices I plug into that switch, but nothing on SW-2 can talk to SW-1 on VLAN 10. Overall, i've tried all variation of methods to get the switches to talk to one another but to no avail. Any help would be greatly appreciated.SW-1
Short answer: Do NOT use hybrid mode. If you're after mixed tagged/untagged VLAN trunking, that's not what hybrid mode means.
Hybrid mode is used with protocol-based VLANs. Without proper configuration, frames all end up in the default VLAN. The only common use case for hybrid mode is a legacy end node that doesn't support tagging but where you still want to separate its traffic into multiple VLANs on the switch side (e.g. an IP phone with a switched PC uplink). Generally, hybrid mode is to be avoided as it does not provide the strict VLAN separation that you likely expect and it can easily create security problems.
Instead, use trunk mode between switches. You can either tag all VLANs (recommended) or leave a single VLAN (the "native") untagged on both sides.
You can always check proper VLAN connectivity by inspecting the MAC table for a specific VLAN. If nodes from one switch aren't visible on a neighbor switch, the trunk's configuration is flawed.
