display ipv6 interface

Function

The display ipv6 interface command displays the information of an IPv6 interface.

Format

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

Parameters

Parameter	Description	Value
interface-type	Specifies the interface type.	-
interface-number	Specifies the interface number.	-
brief	Displays brief information about the interface.	-

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

Ensure that the designated interfaces are assigned IPv6 addresses; otherwise, you cannot view information on the interfaces.

You can run the display interface description command to view the description of the interface.
You can run the display interface command to view detailed information about the operation and statistics of the interface.

Example

# Display the IPv6 information on GigabitEthernet 0/0/1.

**Table 2** Description of the **display ipv6 interface brief** command output
Item	Description
*down:	Indicates the reason that interface is physically Down. Administratively down: indicates that the network administrator runs the shutdown (interface view) command on the interface.
!down	Indicates that the interface goes Down because the number of route prefixes in the FIB exceeds the upper limit.
(l): loopback	The letter "l" refers to loopback.
(s): spoofing	The letter "s" refers to spoofing.
(d): Dampening Suppressed	The interface protocol is in the suppressed state.
Interface	Displays the interface name.
Physical	Displays the physical status the interface: Up Down Administratively Down
Protocol	Displays the status of the link protocol: Up Down
IPv6 Address	Displays the IP address of the interface. If the address is not configured, "unassigned" is displayed.
