display ipv6 interface

Function

The display ipv6 interface command displays IPv6 information on an interface.

Format

display ipv6 interface [ interface-type interface-number | brief ]

Parameters

Parameter	Description	Value
interface-type interface-number	Displays IPv6 information on a specified interface. interface-type specifies the interface type. interface-number specifies the interface number. If no interface is specified, IPv6 information on all interfaces configured with IPv6 addresses is displayed.	-
brief	Displays brief information about the interface.	-

Parameter

Description

Value

interface-type interface-number

Displays IPv6 information on a specified interface.

interface-type specifies the interface type.
interface-number specifies the interface number.

If no interface is specified, IPv6 information on all interfaces configured with IPv6 addresses is displayed.

brief

Displays brief information about the interface.

Default Level

1: Monitoring level

Usage Guidelines

Before running this command, ensure that the interface is configured with an IPv6 address. If no IPv6 address is assigned to the interface, no interface information is displayed.

**Table 1** Description of the **display ipv6 interface** command output
Item	Description
Vlanif2 current state	Current physical status of VLANIF 2. UP: enabled DOWN: disabled
IPv6 protocol current state	Current protocol status of the interface. UP: enabled DOWN: disabled
IPv6 is enabled	IPv6 is enabled.
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.
MTU	MTU of the interface. To configure the MTU for an interface, run the ipv6 mtu command.
ND DAD is enabled	NS packets are sent when the system performs Duplicate Address Detection (DAD).
number of DAD attempts	Number of times duplicate address detection is performed.
ND reachable time	Neighbor reachable time.
ND retransmit interval	Retransmission interval of NS packets.
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.
