DHCP Guard & IP Source guard
Freshman Member
I have 3x XGS2220, in a Stacked configuration & looking to enable both DHCP & IP Source guards. However, it's not an are of networking that I'm particularly familiar with & don't want to change the configuration & risk messing up the network.
Is there a clear step-by-step guide on how to configure these 2 features without blocking network access for users?

Not sure about Stacked configuration as for IP Source guards one thing to keep in mind is DHCP by the client must happen to be allowed so if your thinking of doing this then set DHCP lease to 3 minutes so that when you enable IP Source guards clients come on online without them needing a reboot.
