**Table 1** Description of the **display this ipv6 interface** command output
Item	Description
Vlanif10 current state	Current physical status of VLANIF 10. UP: enabled DOWN: disabled
GigabitEthernet0/0/1 current state	Current physical status of GigabitEthernet0/0/1. UP: enabled DOWN: disabled
IPv6 protocol current state	Current protocol status of the interface. UP: enabled DOWN: disabled
link-local address	Link-local address on the interface. After an IPv6 address is configured on the interface, the system automatically assigns a link-local address for the interface. To manually configure a link-local address for an interface, run the ipv6 address link-local command.
Global unicast address(es)	Global unicast address configured on the interface. To configure a global unicast address for an interface, run the ipv6 address command.
Joined group address(es)	Addresses of all multicast groups that the interface joins.
TENTATIVE	When the interface is in DOWN state, the IPv6 address is TENTATIVE. When the IPv6 address is duplicate with another, this field is DUPLICATE. In normal cases, this field is not displayed.
MTU	MTU of the interface. To configure the MTU for an interface, run the ipv6 mtu command.
ND DAD is enabled	Duplicate address detection (DAD) has been enabled.
number of DAD attempts	Number of times duplicate address detection is performed.
ND reachable time	Neighbor reachable time.
ND retransmit interval	Retransmission interval.
ND stale time	Aging time of ND entries in STALE state.
ND advertised reachable time	Reachable time of NA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND advertised retransmit interval	Retransmission interval of NA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisement max interval 600 seconds, min interval 200 seconds	Maximum and minimum interval of RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisements live for	Router lifetime in RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND router advertisements hop-limit	Hop limit of RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
ND default router preference	Default route priority in RA packets. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
Hosts use stateless autoconfig for addresses	Hosts obtain IPv6 addresses by means of stateless auto-configuration. NOTE: This field is displayed only after the undo ipv6 nd ra halt command is executed on the interface.
