**Table 1** Description of the **display dhcpv6 snooping statistics** command output
Item	Description
DHCPV6 Snooping Statistics	DHCPv6 snooping statistics.
DHCPV6 packets received from clients	Number of DHCPv6 packets received from clients.
Solicit	Number of received Solicit packets.
Request	Number of received Request packets.
Renew	Number of received Renew packets.
Rebind	Number of received Rebind packets.
Inform	Number of received Inform packets.
Release	Number of received Release packets.
Confirm	Number of received Confirm packets.
Decline	Number of received Decline packets.
Relay-forward	Number of received Relay-forward packets.
DHCPV6 packets received from servers	Number of DHCPv6 packets received from servers.
Advertise	Number of received Advertise packets.
Reply	Number of received Reply packets.
Relay-reply	Number of received Relay-reply packets.
DHCPV6 Packets Dropped	Number of discarded DHCPv6 packets.
LDRA distrust relay-forward	Number of Relay-Forward packets discarded by the LDRA untrusted port from the upstream LDRA.
Src mac conflict with server	When the source MAC address of a DHCPv6 packet from a client conflicts with the DHCPv6 server's MAC address, the DHCPv6 packet is discarded. The field indicates the number of DHCPv6 packets discarded for this reason.
Not allow client transfer	After clients are not allowed to change access interfaces, if a DHCPv6 snooping binding entry of a client exists on the original interface and the client attempts to change the access interface, the DHCPv6 packets from this client are discarded. The field indicates the number of DHCPv6 packets discarded for this reason. To configure this item, run the undo dhcp snooping user-transfer enable command.
Fake server	Number of packets discarded by the DHCP Snooping-enabled interface from the DHCPv6 server. To configure this item, run the dhcp snooping enable command.
Reach savi user max number	Number of packets from clients discarded because the maximum number of SAVI binding entries that can be learned by the interface is reached.
Reach dhcp user max number	Number of packets from clients discarded because the maximum number of DHCP snooping binding entries that can be learned by the interface is reached.
untrust relay-forw	Number of Relay-Forward packets discarded by an LDRA untrusted interface.
relay-forward check	Number of discarded DHCPv6 Relay-Forward packets after the dhcpv6 snooping check relay-forward enable command is executed.
DHCPV6 snooping user-bind table deleted	Number of deleted DHCPv6 snooping binding entries.
Receive release packet	Number of binding entries deleted after receiving Release packets.
Receive decline packet	Number of binding entries deleted after receiving Decline packets.
Exceed lifetime	Number of binding entries that are aged out (the lease time is the same as that on client).
User command	Number of binding entries deleted using the command. To configure this item, run the reset dhcp snooping user-bind command.
Client transfer	After a client disconnects from one interface and connects to another one, the binding entry of the client on the original interface is deleted. The field indicates the number of binding entries deleted on original interfaces.
Interface down	Number of binding entries deleted because the interface physical status becomes Down.
Confirm-reply with error code	After a Confirm packet is received, a binding entry is generated. If a Reply packet in which the status code is not 0 is received within the timeout period (10 seconds), the generated binding entry is deleted. The field indicates the number of binding entries deleted for this reason.
Confirm-client offline	After the confirm-client probing function is enabled, an NA packet is returned for every DAD NS packet. If no NA packet is received when the maximum number of retransmission times of a DAD NS packet is reached, the binding entry is deleted. The field indicates the number of binding entries deleted for this reason.
DAD NS packets sent to clients	Number of DAD NS packets sent for confirm-client probing.
NA packets received from clients	Number of NA packets received from confirm-client probing.
