*down: administratively down
(s): spoofing
Interface
Vlan-interface1
VLAN interface link state:
Administratively DOWN: Indicates the VLAN interface is
administratively down; that is, the interface is shut down using the
shutdown command.
DOWN: 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.
UP: Indicates the administrative and physical states of the VLAN
interface are both up.
Link layer protocol state of an interface:
DOWN: Indicates the link layer protocol state of the VLAN
interface is down, generally because no IP address is configured.
UP: Indicates the link layer protocol state of the VLAN interface is
up.
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)
Link-local address configured on an interface
Aggregatable global unicast address configured on an interface
Address of the multicast group that an interface joins
Maximum transmission unit of an interface
Number of duplicate address detection (DAD) attempts, with DAD
enabled
If DAD is enabled, the number of neighbor request messages is
also displayed (configured by using the ipv6 nd dad attempts
command)
If DAD is disabled, "ND DAD is disabled" is displayed. (You can
set the number of neighbor request messages for DAD to 0 to
disable this function.)
Neighbor reachable time (which can be configured by using the ipv6
nd nud reachable-time command)
Interval for retransmitting a neighbor solicitation (NS) message
(which can be configured by using the ipv6 nd ns retrans-timer
command)
Hosts use stateless auto-configuration mode to acquire IPv6
addresses
