• Administratively DOWN—The VLAN interface has been
administratively shut down by using the shutdown command.
• DOWN—The VLAN interface is administratively up but its physical
state is down because all ports in the VLAN are down.
• UP—The administrative and physical states of the VLAN interface
are both up.
Line protocol current state
Link layer protocol state of the interface:
• DOWN—The link layer protocol state of the VLAN interface is down.
• UP—The link layer protocol state of the VLAN interface is up.
IPv6 is enabled
IPv6 is enabled on the interface. This function is automatically enabled
after an IPv6 address is configured for an interface.
link-local address Link-local address of the interface.
Global unicast address(es)
Global unicast addresses of the interface.
IPv6 address states:
• TENTATIVE—Initial state. DAD is being performed or is to be
performed on the address.
• DUPLICATE—The address is not unique on the link.
• PREFERRED—The address is preferred and can be used as the
source or destination address of a packet. If an address is in this
state, the command does not display the address state.
• DEPRECATED—The address is beyond the preferred lifetime but in
the valid lifetime. It is valid, but it cannot be used as the source
address for a new connection. Packets destined to the address are
processed correctly.
If a global unicast address is not manually configured, the following
indicates how the address is obtained:
• AUTOCFG—Stateless autoconfigured.
• DHCP—Assigned by a DHCPv6 server.
• EUI-64—Manually configured EUI-64 IPv6 address.
• RANDOM—Random address automatically generated.
If the address is a manually configured anycast address,
ANYCAST
is
marked.
valid lifetime
Specifies how long autoconfigured global unicast addresses using a prefix
are valid.
preferred lifetime
Specifies how long autoconfigured global unicast addresses using a prefix
are preferred.
Joined group address(es) Addresses of multicast groups that the interface has joined.
MTU Maximum transmission unit (MTU) of the interface.
ND DAD is enabled, number of
DAD attempts
DAD is enabled.
• If DAD is enabled, this field displays the number of attempts to send a
NS message for DAD (set by using the ipv6 nd dad attempts
command).
• If DAD is disabled, this field displays ND DAD is disabled. To disable
DAD, set the number of attempts to 0.
ND reachable time Time during which a neighboring device is reachable.
ND retransmit interval Interval for retransmitting an NS message.
Hosts use stateless autoconfig
for addresses
Hosts obtained IPv6 addresses through stateless autoconfiguration.
InReceives All IPv6 packets received by the interface, including error packets.
