"Advanced Engineering Certification - Wired Module 14": Multiple VLAN untagged???
Hello, in Netgear Academy, "Advanced Engineering Certification - Wired", Module 14, ports are untagged in VLAN 1; at 06:20, some ports are added untagged to VLAN 10, too. I could only replicate this when the port is in General Mode, not in Trunked or Access mode. I am sorry if this is a newbie question. From what I understand, * every port can sensefully only have one VLAN untagged, the rest has to be tagged, as untagged denotes the direct VLAN untagged packets can be sent to. Please correct me if I am wrong here. * "General" mode is kind of an "Auto" mode where the port itself decides whether it should act "Access" or "Trunked", so if I configure a port, I understand it that this configuration should work either in "Access" or in "Trunked, whichever is the actual mode I am working in? So, this behaviour opens a lot of questions, namely which is the "real" untagged VLAN, and how it could be configured as "untagged" in multiple VLAN. Note: As I am using devices I have at work that could be spared, I am using a M4250-10G2XF-PoE++, not the Netgear M4350-36X4V the learning video uses. However, regardless, I could replicate the behaviour of the switch in the tutorial video; and to me, there still is no sense in multiple VLAN being "untagged" for a single port. Could perhaps somebody point me to sources where I can research this, or help out here? Thanks, and greetings from the Franco-German borderlands, Yours Ralf
