I had anotther thread from a few days ago, but I have some more information now and want to ask a different question.
EX4300 VC on 14.1X53-D46.7 with mainly wireless clients. When the clients move around and connect to an access point on a different subnet than their previous one, the do not obtain a new IP address. Wireshark shows them making repeated requests (broadcast) that the server does not see.
I understand that then the DHCP relay see the ACK from the server, the creates a binding for that client (MAC address), and the IRB interface interface:
When the client moves and connectes to a different subent, the fact that this record exists prevents the switch from forwarding the DHCP Request braodcasts to the server. If I manually delete the binding, the server recieves the very next DHCP Request, and is able to reply with a NAK, prompting the client to immediatley start the DORA process and get an IP and a new binding.
How can I force the switch to discard/overwrite the old binding when the client attempts DHCP from a new subent, or disable the binding process all together if doing so allows clients to move around unhindered by 1-3 minutes of waiting for this record to age out?
I had no problem with DHCP on the EX4200s I took out less than 2 weeks ago.
Yes, I gave that a try but it did not help. I think because the documentaton states it is ment to tirgger on DHCP Discover packets. I have no problem getting an IP if the client starts with a Discover. Only an issue if they are sending "Request" broadcasts
