28.8 IPv6 Sno o ping Polic y Se tup
Use this screen to dynamically create an IPv6 source guard binding table using a DHCPv6 snooping
policy. A DHCPv6 snooping policy lets the Switch sniff DHCPv6 packets sent from a DHCPv6 server to a
DHCPv6 client when it is assigning an IPv6 address. When a DHCPv6 client successfully gets a valid IPv6
address, DHCPv6 snooping builds the binding table dynamically. To open this screen, click Adva nc e d
Applic a tio n > IP So urc e G ua rd > IPv6 Sno o ping Po lic y Se tup.
Note: If you do not select Pro to c o l and Pre fix Gle a n, then the Switch cannot perform DHCPv6
snooping.
