Unable to get trunk to Cisco switch to function

Installing and Using OpenWrt
1

I am trying to get a trunk functional between my Asus RT-AX54 running 24.10 and a Cisco 2960 to no avail. The Cisco side dot1q encapsulation, native vlan 1, allowed VLANs 1,100-102. Pretty standard stuff. I just can't seem to see what I am doing wrong on the Asus side. I have a simple bridge, the four vlans defined, and vlan filtering turned on. I am managing via Luci and SSH via the WAN port as to not interfere with what I am trying to accomplish. Hoping someone notices something. Thanks in advance.

bridge-vlans are always tagged to the CPU, so you need to change the lan interface's Device to br-lan.1

The 8021q sections are used by Luci for housekeeping to populate lists; they don't affect hardware at all and can be left out of a CLI configuration.

Some chips and drivers do not work with tagged and untagged on the same port. For best compatibility set up your network so that every VLAN present on a trunk cable is tagged.
