**Table 1** Description of the **display dhcpv6 lease-proxy-table** command output
Item	Description
Total Users	Total number of DHCPv6 lease proxy users on a board.
Vlan	Vlan.
Interface	Interface.
User-id	User id.
UserMac	UserMac.
Vpn-instance	Vpn instance.
OrigStart	Start time of the server-end lease of the DHCPv6 lease proxy user.
OrigT1	T1 recorded on the server for the DHCPv6 lease proxy user.
LastRenew	Time when the DHCPv6 lease proxy user successfully performed renewal last time. The time is updated in the following scenarios: The BRAS completes user lease renewal. The DHCPv6 server completes user lease renewal. The BRAS automatically updates the time on the slave board in NPU 1:1 scenarios. The BRAS automatically updates the time on the slave device in RUI scenarios. The BRAS automatically updates the time on a non-main-processing Trunk board.
Preferred-lifetime	Preferred lifetime value for DHCPv6 lease proxy users. If the configured value is less than 300s, the device may dynamically adjust the value based on the CPU usage. The adjusted value may be different from the configured value.
Valid-lifetime	Valid lifetime value of a DHCPv6 lease proxy user. If the preferred lifetime value configured by the user is less than 300s, the device may dynamically adjust the lifetime value based on the CPU usage. The adjusted lifetime value may be different from the configured one. To prevent users from going offline due to lease changes on the master and backup devices during reliability operations, the user login user is not the master processing board, the backup user in dual-system hot backup scenarios, the backup interface board of the master and backup interface boards, and before the DHCPv6 lease proxy is enabled for the first time and lease renewal is not performed, the validity period of the proxy lease is changed to 300s.
Receive Renew	Number of Renew packets received by the DHCPv6 lease proxy user.
Receive Rebind	Number of Rebind packets received by the DHCPv6 lease proxy user.
Send Reply	Number of Reply packets sent by the BRAS to the client.
Send to server	Number of user packets sent to the server.
User detect	Proactive ND detection for the DHCPv6 lease proxy user. -0:disable. -1:enable.
IPv6 Address	IPv6 address of the lease proxy user.
IPv6 PD Prefix	IPv6 prefix of the lease proxy user.
OrigT2	T2 recorded on the server for the DHCPv6 lease proxy user.
OrigPreferTime	Preferred lifetime value recorded on the server for the DHCPv6 lease proxy user.
OrigValidTime	Valid lifetime recorded on the server for the DHCPv6 lease proxy user.
InvalidFlag	This field is set to 1 when the original remaining lease period is less than the sum of the proxy lease period and proxy lease period T1 and is set to 0 after a successful lease renewal from the server. The priority of this field is higher than that of T1ReplyFlag and T2ReplyFlag.
T1ReplyFlag	This field is set to 1 when the client fails to renew the lease before the original T1 lease arrives and is set to 0 after a successful lease renewal from the server.
T2ReplyFlag	This field is set to 1 when the client fails to renew the lease before the original T2 lease arrives and is set to 0 after a successful lease renewal from the server.
Slot Id	Slot of the lease proxy user.
