Hello,

I have a Cisco Catalyst 2950T-48-SI with 48 ports 100Base-T and 2
ports with 1000Base-T and a 50 floor building. On each of the 48 ports
there is a floor connected and each floor has its own VLAN, for
security reasons. Port 1 for floor 1 has VLAN ID 10 native, port 2 for
floor 2 has VLAN ID 11 native and so on.
On the Linux Server (Debian sarge) I' run dhcp3, I've worked with dhcp
before and I'm familiar to it. The server is connected on one of the
1000Base-T ports.

The problem begins here... On the server I have virtual interfaces for
each port(VLAN), for example for floor 1 i have eth1.10, for floor 2 I
have eth1.11.
Can I start dhcp with the -q eth1.10 eth1.11 eth1.xx? or I need to
start it with the -q eth1 option, but then I don't think that is will
work... because eth1 has no ip address and the packets sent from it
are each one tagged with their specific VLAN ID.

So... Anyone tried this? Or can anyone tell me if it will work or not?
I can't afford to test this...


Thank you all!
Have a great day!
