Re: DHCP across vlans not working
I have removed the trk1 which was LACP between the 2 switches for a 2 GB connection. It is now just a single link to see if that helps my situation.

Re: DHCP across vlans not working
Default VLAN for servers
VLAN lvl1
VLAN lvl2
Now everyone on lvl1 is plugged into the Procurve switch and all is well.
Everyone on lvl2 is plugged into the 3com Baseline switch and are having trouble getting DHCP addresses. The 3com 2948 Baseline is a layer2 switch with all ports set to VLAN25 lvl2.
I setup wireshark and ran it on both workstations on each level unfortunately I got the same result for both floors which is not good as the second floor is not working all the time. Have attached the wireshark output from the problem floor when releasing and renewing the IP address in cmd.
Thanks for your help so far but am getting deperate and running out of ideas.

Re: DHCP across vlans not working
must have connect vlan 1 untag port
(because 172.16.45.0 network have vlan 1)
but I see your dhcp server connect on vlan 25
it is not working
please test and say me result
your 3com switch uplink port connect hp switch port 42
and dhcp server default gateway address must have 172.16.45.1
