On a multiple Vlan network I have two Vlans that are in my domain group. One is funcitoning fine while the other is not. If I place any client in the group that is not to accept BOOTP lease it works fine it is something to do with the request and reply for the WINS or NetBIOS type81 request on devices that reside on my secondary network or VLAN. One note the WINS and DNS servers that are given as reply to the clients are on the primary vlan and not on this non working secondary.
For a client that worked the packet sequence seen on its switch port was:
Client -> Broadcast DHCP Discover (I want 141.211.###.###) 12.92 -> 141.211.###.### DHCP Offer (You can have 141.211.###.###) Client -> Broadcast DHCP Request (I accept 12.92's offer) 14.27 -> 141.211.###.### DHCP Offer (You can have 141.211.###.###) 12.92 -> 141.211.###.### DHCP ACK (You've got 141.211.###.###)
Note that the client sent its Request before the second offer from 14.27 arrives.
For a client that didn't work:
Client -> Broadcast DHCP Discover (I'll take anything) 12.92 -> 141.213.###.### DHCP Offer (You can have 141.213.###.###) 14.27 -> 141.213.###.### DHCP Offer (You can have 141.213.###.###) Client -> Broadcast DHCP Request (I accept 12.92's offer) Client -> Broadcast DHCP Request (I accept 12.92's offer) Client -> Broadcast DHCP Request (I accept 12.92's offer) Client -> Broadcast DHCP Request (I accept 12.92's offer)
But it never gets an ACK from 12.92.
