The ipsg enable command enables IP source guard (IPSG) on an AP's wired interface.
The undo ipsg enable command disables IPSG on an AP's wired interface.
By default, IPSG is disabled on an AP's wired interface.
Usage Scenario
Attackers often use packets with the source IP addresses or MAC addresses of authorized users to access or attack networks. As a result, authorized users cannot obtain stable and secure network services. You can enable the IPSG function to prevent the situation.
Prerequisites
Terminal address learning has been enabled on the AP's wired interface using the learn-client-address enable command.
Follow-up Procedure
Bind the AP wired port profile to an AP group or AP.
Precautions
This command takes effect only on IP packets transmitted on an AP's wired interface.
The AP wired interfaces added to an Eth-trunk interface do not support this function.
