The fields that can be configured in IPv6 Snooping Policy Settings are described below: Parameter Policy Name Limit Address Count Protocol Description Enter the IPv6 snooping policy name used here. This name can be up to 32 characters long. Enter the address count limit value used here. The range is from 0 to 1024. By default, this value is 1024. Select the No Limit option to use the default value. Select the protocol state here. Options to choose from are:  DHCP - Specifies that addresses should be snooped in DHCPv6 packets.  NDP - Specifies that addresses should be snooped in NDP packets.  DHCP-PD - Specified that IPv6 prefix should be snooped in DHCPv6 PD packets. DHCPv6 snooping sniffs the DHCPv6 packets sent between the DHCPv6 client and server in the address assigning procedure. When a DHCPv6 client successfully got a valid IPv6 address, DHCPv6 snooping creates its binding database. ND Snooping is designed for a stateless auto-configuration assigned IPv6 address and manually configured IPv6 address. Before assigning an IPv6 address, the host must perform Duplicate Address Detection first. ND snooping detects DAD messages (DAD Neighbor Solicitation (NS) and DAD Neighbor Advertisement (NA)) to build its binding database. The NDP packet (NS and NA) is also used to 525
