Protect your network from rogue DHCP servers with Cisco switches

This will protect your network from rogue DHCP servers.

ip dhcp snooping

#Globally enables it

ip dhcp snooping vlan (whatever vlan's your want to protect)

interface gi1/1/1

#This would be the interface that your DHCP server is on, can also be a trunk if it's upstream

ip dhcp snooping trust

#Allow DHCP from whatever interface this is on

Show ip dhcp snooping

#This will show you a summary of what you've setup

I'll add some screenshots for this config later.
