Guidelines
After the ip-source-guard function is enabled, by listening the interactions between the
client and server, the IP addresses allocated by the server to the client are recorded and
the messages with other source IP addresses are filtered to prevent spoofing.
Before enabling the ip-source-guard function, you must enable the DHCPv6 snooping
function.
Examples
The following example enables the ip-source-guard function for ports 9 and 10:
zte(cfg)#set dhcpv6 ip-source-guard add port 9-10
Fail to enable ip v6 source guard on port 9.
% DHCP v6 snooping is disabled on this port (0x4000092a)
