DHCP Snooping


Userlevel 1
I'm currently testing Cumulus VX and was wondering how you set dhcp snooping on a switch? Currently with Cisco, it's "ip dhcp snooping" and "ip dhcp snooping vlan ."

Hey B,

DHCP snooping is not currently supported on Cumulus Linux. I am sure if you gave us a use-case and talked to an SE we could come up with a game plan for you. Email me at sean at cumulusnetworks.com if you don't already know your SE at Cumulus and I will get them in touch with you.

I don't believe that DHCP snooping is supported yet.

Thanks Kevin, Sean recently confirmed that it's not supported at this time.

In case it is of use to you... here's a BASH script that provides some basic DHCP trusted port functionality. It doesn't handle individual VLANs but instead uses the trusted port model to allow DHCP on particular interfaces. https://gist.github.com/ericpulvino/bc741227efe4a8b3bdd229e4f4fef40b
