**Table 1** Description of the **display dhcpv6-access statistic** command output
Item	Description
Received Packets	Indicates the number of received packets.
Received from Clients	Indicates the number of received packets from clients.
Received from Servers	Indicates the number of received packets from the DHCPv6 server.
Received Invalid Packets	Indicates the number of received invalid packets from the client and the server. This field does not count all error packets. Therefore, the combined number of packets with a specific error must be greater than the value of this field.
Packets	packets.
Total Packets	Indicates the total number of received packets. The total number of received packets is the sum of the following: Solicit packets, Request packets, Renew packets, Rebind packets, Confirm packets, Release packets, Decline packets, Advertise packets, Reply packets, packets with invalid UDP length, packets with null client DUID, packets with null server DUID, packets with invalid IA option length, packets with invalid client DUID length, packets with invalid server DUID length, packets with invalid server DUID, and other invalid packets.
Advertise Packets	Indicates the number of sent/received Advertise Packets.
Invalid UDP Length	Indicates the number of packets with invalid UDP length collected before packet parsing.
Invalid IA Option Length	Indicates the number of packets with invalid IA option length collected before packet parsing.
Invalid Client DUID Length	Indicates the number of packets with invalid client DUID length collected before packet parsing.
Invalid Server DUID Length	Indicates the number of packets with invalid server DUID length collected before packet parsing.
Invalid Server DUID	Indicates the number of packets with invalid server DUID collected before packet parsing.
Invalid Unicast Option	Indicates the number of packets with invalid unicast option collected after packet parsing. The number of packets with invalid unicast option is not greater than the sum of Solicit Packets, Request Packets, Renew Packets, Rebind Packets, Confirm Packets, Release Packets, Decline Packets, Advertise Packets, and Reply Packets. Statistics on Invalid Unicast Option and Invalid Preference Option may be collected repeatedly. This is because packets may continue to be parsed after the two errors occur at the same time. However, there is a low probability that this problem occurs.
Invalid Preference Option	Indicates the number of packets with invalid preference option collected after packet parsing. The number of packets with invalid preference option is not greater than the sum of Solicit packets, Request packets, Renew packets, Rebind packets, Confirm packets, Release packets, Decline packets, Advertise packets, and Reply packets.
NULL Client DUID	Indicates the number of packets with null client DUID collected before packet parsing.
NULL Server DUID	Indicates the number of packets with null server DUID collected before packet parsing.
NULL IA Option	Indicates the number of packets with null IA option collected before packet parsing. The number of packets with null IA option is not greater than the sum of Solicit packets, Request packets, Renew packets, Rebind packets, Confirm packets, Release packets, Decline packets, Advertise packets, and Reply packets.
Server Ip Inconsistent	server IP inconsistent.
Reconfigure Packets	Indicates the number of sent Reconfigure packets.
Reconfigure From Client	reconfigure from client.
Other Invalid Packets	Indicates the number of other invalid packets collected before packet parsing.
Sent Packets	Indicates the number of sent packets.
Sent to Clients	Indicates the number of packets sent to users.
Sent to Servers	Indicates the number of packets sent to the DHCPv6 server.
