VLAN-ID - parent Interface ?



  • Hi,

    I have got a silly question. I know, what VLANs are  and how they work. If I assign several VLANs to my ethernet card on LAN side, then I have to assign a VLAN-ID for every VLAN but which ID has the parent interface ?

    Does it make sense to use the parent interface if I use a switch with VLAN capability or should I only use the child VLAN interfaces ?

    If I remember correct, I read, that the captive portal doesn't work with the parent interface if I use several VLANs. Is this correct ?

    Thanks for your help.



  • In general it is recommended to NOT mix use of parent interface with VLANs. There are complications if bridges are involved. See the FreeBSD man pages for vlan and bridge.
