QFX5100 and DHCP snooping

Hi!

I have:

QFX5100-48S-6Q

Junos: 17.4R1.16

I want to configure DHCP snooping for protect my network from other DHCP servers...

I use this guide: https://www.juniper.net/documentation/en_US/junos/information-products/pathway-pages/qfx-series/security.pdf

But I don't see any working config.

QFX5100 support DHCP snooping ?
