Security > IPv6 Source Guard > Configuration
This page provides IPv6 Source Guard related configuration.
IPv6 Source Guard is a security feature used to restrict IPv6 traffic on DHCP snooping untrusted ports by filtering
traffic based on the DHCPv6 Snooping Table or manually configured IPv6 Source Bindings. It helps prevent IP
spoofing attacks when a host tries to spoof and use the IPv6 address of another host.
Mode: Enable or disable IPv6 Source Guard globally.
Port Mode Configuration: The table shows all ports on the device. IPv6 Source Guard can be enabled or
disabled on individual ports. IPv6 Source Guard is enabled on a given port only when both Global Mode and Port
Mode are enabled on that port.
Max Dynamic Clients: This value can be 0, 1, 2 or unlimited. If the Port Mode is enabled and the value of Max
Dynamic Clients is 0, only IPv6 packets that are matched in static entries on the specific port are forwarded.
