Package: isc-dhcp-server
Version: 4.1.1-P1-15+squeeze3
Severity: normal
Hi,
I have a setup where the server is connected to a switch via a trunking port --
however the switch management is untagged, so I have to run the DHCP server on
both the regular interface and the vlan interfaces.
When a request comes in with a tagged packet, it is seen twice, and responded to
with two different configurations, i.e. I see
<- DISCOVER via eth1.2
-> OFFER via eth1.2
<- DISCOVER via eth1
-> OFFER via eth1
<- REQUEST via eth1.2
-> ACK via eth1.2
<- REQUEST via eth1
-> NAK via eth1
I'm not sure if this is more than an annoyance, but I doubt it should happen.
Simon
