will detect the source addresses of the received data packet, if it match the binding entries, then t he IP v6
packet are allowed to pass, otherwise, the IP v6 packet are denied.
Configuration steps:
SW1:
SW1(config)# ipv6 enable
SW1(config)# ipv6 nd snooping enable
SW1(config)# interface vlan 1
SW1(config-if-vlan1)# ipv6 address 2001::1/64
SW1(config)# interface ethernet 1/1; 1/2; 1/3
SW1(config-if-port-range)# ipv6 nd snooping user-control
SW2:
SW2(config)# ipv6 enable
SW2(config)# interface vlan 1
SW2(config-if-vlan1)# ipv6 address 2001::2/64
SW2(config-if-vlan1)# no ipv6 nd suppress-ra

27.4 ND Snooping Troubleshooting

If there is any problem happens when using ND Snooping, please check whether the problem is caused by
the following reasons:
 Whether ipv6 nd snooping enable is enabled globally and ipv6 nd snooping user-control is configured in
the port.
 Use debug ipv6 nd snooping to check whether the switch can correctly receive and process the relative
packets.
