I cant get dhcp to relay...
If i manually set IP's i can ping across vlan's just fine...
If I am on the same switch, and same vlan, i can get an address...
If I am on a different switch, but same vlan... i get nothing...
Different switch different vlan... nothing
Same switch different vlan.. nothing...
I set up all vlan's to use the helper ip and enabled dhcp relay...
what gives...?
Solved! Go to Solution.

Re: DHCP... What Gives...
Also seen a few instances lately where the 5400 just needs to be rebooted for DHCP-Relay to work properly.
Don't forget to assign points along the way to any replies you receive.

Keep the IP address of VLAN1, it's fine since it is different to the 5300. You need to do is remove the IP address on VLAN 10 (which is the same as the IP address on the 5300). You also need to remove those IP addresses on all those other VLANs.
You could also give those VLANs different IP addresses, e.g 10.3.10.2, but there's no need.
