hello,

does anyone know how to activate a VLAN interface with mac os x 10.2.6? the kernel seems to have a VLAN network extention but ifconfig doesnt seem to know about how to add/configure a vlan. i need to be member of different tagged VLAN's in the company where i work.

thanks,
cjm
 
alice - A virtual lan ( VLAN ) is implemented on the switch portion of your network. Your lan admin will have to change your RJ45 jack to that of another VLAN where you need to be.

hi,

no, i need tagged VLAN support on the machine to be able to be
member of more than 1 VLAN's. untagged VLAN's of course work
cause the OS doesnt need to know about VLAN-tagging and over-
sized ethernet frames.

regards
 
It is not just an OS issue your NIC needs to be able to see the tagged vlans. Back when I was messing with them most NICs could not handle them, I think we used alteon cards but I may be wrong. Are your sure that the NIc you have supports a trunked lan line?

you are of course correct. not all
NICs can handle oversized frames.
today most of the cards should be
able to do that (intel etherexpress 10/100, rtl 8139, 3c905b,...)

vlan (802.1q) =! trunked ports...

it was more of a generel question if
802.1q generally works under the
darwin kernel... i found this in the
kernel source:

src/xnu/bsd/net/if_vlan.c
src/xnu/bsd/net/if_vlan_var.h
src/xnu/BUILD/obj/RELEASE_PPC/bsd/RELEASE/vlan.h

but there seem to be no userland tools
to configure a vlan...

later,
