SRW224G4 w/ vLan DHCP NAK responses for Macbook!

[Ptkferraro]

HI all,

After some wireshark, I see that when I have a vLan on the switch, only win7 gets IP, my macbook doesn't, sniffing to the bootp, I see that the DHCP sends NAK and after I only have DISCOVER & OFFER...

When I get the same switch and the same router and take out the vLan on the switch, everybody get an IP.

What's the deal with this switch and vLans and Mac OS x ???

Do I have to setup something else ?

cheers

DHCP NAK means the DHCP server is refusing to give an IP to the client.  it might be that the client is requesting an already used IP, or is requesting an IP that does not fit within the scope defined for the VLAN or network the client is on.  in any case, the NAK is not likely because of the the switch.  check your dhcp server logs.
