(Single choice) The following statement about defense MAC Spoofing is wrong

MAC Anti- Mac Spoofing' features are mutually exclusive with WMAC, SC, PPPOE SMAC features at the VLA level

After the anti-MAC Spoofing function is enabled, the system automatically implements the dynamic binding of the AC address to the service flow

After enabling the Anti-MAC Spoofing function, for IPoE users using fixed IP, the user needs to be statically configured

Turning off the Anti-MAC Spoofing function can only take out the fixed table items, which does not affect the user's service application, but the service forwarding surface will be interrupted.
