Chapter 1 IPv6 Configuration Commands
1.1 Basic IPv6 Configuration Commands
1.1.1 display dns ipv6 dynamic-host
Syntax
display dns ipv6 dynamic-host
View
Any view
Parameters
None
Description
Use the display dns ipv6 dynamic-host command to display IPv6 dynamic domain
name information in the cache, including the domain name, IPv6 address, and TTL of
the DNS entries.
You can use the reset dns ipv6 dynamic-host command to clear all IPv6 dynamic
domain name information from the cache.
Examples
# Display IPv6 dynamic domain name information in the cache.
<Sysname> display dns ipv6 dynamic-host
No. Domain-name IPv6 Address TTL
1 aaa 2001::2 6
Table 1-1 Description on the fields of the display dns ipv6 dynamic-host command
Field Description
No. Sequence number
Domain-name Domain name
IPv6 Address IPv6 address of the corresponding domain name
TTL Time-to-live of the domain name in the cache in seconds

Note:
When you use the display dns ipv6 dynamic-host command to check the IPv6
dynamic domain names in the cache, the system will display the first 21 characters of
the domain names if they contain more than 21 characters. This is because the domain
name displayed in the Domain-name field can be up to 21 characters in length.

Syntax
display ipv6 fib
View
Any view
Parameters
None
Description
Use the display ipv6 fib command to display all the IPv6 FIB entries.

addresses can be configured is displayed; if only interface-type is specified, the IPv6
information of the interfaces of the specified type for which IPv6 addresses can be

VLAN interface link state:
zAdministratively DOWN: Indicates the VLAN interface
is administratively down; that is, the interface is shut
down using the shutdown command.
zDOWN: Indicates the VLAN interface is
administratively up but its physical state is down; that
is, no ports in the VLAN are up, which may be caused
by a link failure.
zUP: Indicates the administrative and physical states of
the VLAN interface are both up.
Line protocol current

Link layer protocol state of an interface:
zDOWN: Indicates the link layer protocol state of the
VLAN interface is down, generally because no IP

interface is up.
IPv6 is enabled
IPv6 forwarding state of an interface (after an IPv6
address is configured for an interface, IPv6 is
automatically enabled on it; IPv6 is enabled in the
example)
