IPv6 DHCP Snooping Dynamic Bindings

Use the IPv6 DHCP Snooping Dynamic Bindings page to view and clear dynamic bindings in the IPv6 DHCP (Dynamic Host Configuration Protocol) snooping bindings database. The IPv6 DHCP snooping feature uses DHCPv6 messages to build and maintain the bindings database. The bindings database includes data for clients only on untrusted ports.

IPv6 DHCP snooping creates a tentative binding from DHCPv6 SOLICIT and REQUEST messages. Tentative bindings tie a client to an interface (the interface where the DHCPv6 client message was received). Tentative bindings are completed when IPv6 DHCP snooping learns the client's IP address from a REPLY message on a trusted port. IPv6 DHCP snooping removes bindings in response to DECLINE and RELEASE messages.

Interface The interface on which the DHCPv6 client message was received.
MAC Address The MAC address associated with the DHCPv6 client that sent the message. This is the key to the binding database.
VLAN ID The VLAN ID of the client interface.
IP Address The IPv6 address assigned to the client by the DHCPv6 server.
Lease Time The remaining IPv6 address lease time for the client.
Clear (Button) To remove one or more entries in the database, select each entry to delete and click Clear. You must confirm the action before the entry is deleted.
