You cannot enable dynamic IPv6 source guard on a service loopback interface.
This command only enables IP source guard packet filtering on a port. The port uses static IPv6 source
guard entries to filter packets without considering the keywords specified in the command.
Examples
# Enable IPv6 source guard on Ethernet port Ten-GigabitEthernet 1/0/1 to filter packets received on the
port.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] ipv6 verify source ip-address mac-address

Parameters
static: Clears static IPv4 source guard entries.
vpn-instance vpn-instance-name: Clears dynamic IPv4 source guard entries for a VPN. The
vpn-instance-name argument is the VPN instance name of an MPLS L3VPN, a case-sensitive string of 1
to 31 characters. If you do not specify a VPN, the command clears dynamic IPv4 source guard entries for
the public network.
dhcp-relay: Clears dynamic IPv4 source guard entries created by DHCP relay.
dhcp-server: Clears dynamic IPv4 source guard entries created by DHCP server.
dhcp-snooping: Clears dynamic IPv4 source guard entries created by DHCP snooping.
ip-address ip-address: Clears IPv4 source guard entries for an IPv4 address.
Usage guidelines
If you do not specify any parameter, the command clears IPv4 source guard entries on all interfaces on
the public network.
Examples
# Clear all IPv4 source guard entries on the public network.
