How to block DHCP traffic on a specific port - HP 2650 or HP 2524
Hello,
I just want to block all the broadcast requests on a specific port, specially for DHCP ones, using one of my two network switches.
The documentation tells me that I can use the broadcast-limit command in order to do it, and I set the values on the interested ports to zero.
But oppositely to the expected behavior, the clients connected to my port continue to find my DHCP server receiving an address.
In fact, when I monitor the port counters, I can see that a lot of BCast packet was sent and received through the interfaces I set with a broadcast-limit of zero.
Is this expected? How can I block all DHCP requests on a specific port?
thank you

Hi giacomelli
You can block UDP Port 67 and 67 with an ACL. Unfortunately I dont now how to configure on an ex-Procurve. (because I'm a ex-3com/h3c user) Check the manual for the answer.
