# Configure the IPv6 source guard function on Ethernet 1/0/1 to filter packets based on both the source
IP address and MAC address.

Verifying the configuration
# On Device, display the information about static IPv6 source guard binding entries. The output shows
that the binding entry is configured successfully.

configuration example
Network requirements
As shown in Figure 124, the host (DHCPv6 client) and the DHCPv6 server are connected to the device
through ports Ethernet 1/0/1 and Ethernet 1/0/2 respectively.
Enable DHCPv6 and DHCPv6 snooping on the device, so that the host can obtain an IP address through
the DHCPv6 server and the IPv6 IP address and the MAC address of the host can be recorded in a
DHCPv6 snooping entry.
Enable IPv6 source guard function on the device’s port Ethernet 1/0/1 to filter packets based on
DHCPv6 snooping entries, allowing only packets from a client that obtains an IP address through the
DHCP server to pass.
