Protocol filtering vs port filtering

Dear Airheads experts,

 

We need a protocol level filter for dhcp traffic (not only port level udp 67, 68). Can I do this with Aruba controller for example with basic PEF or application level filter? I saw a dhcp6 application on the controller but I don't know what does it mean exactly.

 

Thank you in advance for your help!

Hi Colin,

 

Our security team wants to make sure that only dhcp traffic goes through on udp 67, 68. So if it is possible we need a protocol filter.

 

Thanks,

How is your security team doing this for their wired network?

Unfortunately I don't know.

 

But is there any recommendation about that or some controller side configuration possibility?

I have never heard of that before.  Most of our features are based on real-world applications.
