My guess is that the guy who set them up tried to remove the default vlan before adding the tagged vlans. It is not neccessary to have an untagged vlan on a trunk port, but you cannot remove an untagged vlan from a port that has nothing tagged yet. If you do it like this you will be able to remove the native vlan:

Does each VLAN need its own dedicated uplink port on the switch and firewall (acting as a router)? If both sides support 802.1Q VLAN tagging you can set up a single VLAN trunk (or aggregated ports) for all VLANs. One of the VLANs may be untagged (sometimes called the native VLAN), all the others must be tagged on both side in the same manner.

27.08.2021 · Meraki APs use tag-based VLANs (i.e., VLAN tagging) to identify wireless traffic to an upstream switch/router. When the switch/router sees VLAN- tagged traffic from a Meraki AP, it can apply different policies to that traffic, including access control (e.g., send traffic straight to the firewall for Internet-only access) or QoS (e.g., prioritize traffic on the VOIP SSID).

01.10.2017 · In his case, VLAN 10 is his untagged VLAN on the watchguard, so he would need to tag the others on the uplink. That has no bearing on other devices connected to other ports. Those are tagged or untagged based on the device connected to that port and how it's configured.

It applies a VLAN tag to outgoing traffic on the WAN port, so it can support fibre ISPs that require a VLAN tag for internet traffic. It also removes the same tag from incoming traffic. That's all. Loop detection should always be turned off on any switches that connect to an eero.

WAN Uplink VLAN tag. A virtual LAN (VLAN) is a local area network that categorizes client devices and workstations despite their geographic location.
