Table 12-2 display ipv6 interface command output description 
Field  Description 
Vlan-interface2 current state 
Physical state of the interface:  
z  Administratively DOWN: Indicates that the VLAN interface is 
administratively down; that is, the interface is shut down using the 
shutdown command. 
z  DOWN: Indicates that 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 connection or link failure. 
z  UP: Indicates that the administrative and physical states of the 
VLAN interface are both up. 
Line protocol current state 
Link layer protocol state of the interface: 
z  DOWN: Indicates that the link layer protocol state of the VLAN 
interface is down, generally because no IP address is configured. 
z  UP: Indicates that the link layer protocol state of the VLAN interface 
is up. 
IPv6 is enabled 
IPv6 packet forwarding state of the interface (after an IPv6 address is 
configured for an interface, IPv6 is automatically enabled on it; IPv6 
packet forwarding is enabled in the example) 
link-local address  Link-local address configured for the interface 
Global unicast address(es)  Aggregatable global unicast address(es) configured for the interface 
valid lifetime  Valid lifetime of the global unicast address 
preferred lifetime  Preferred lifetime of the global unicast address 
Joined group address(es)  Address(es) of multicast group(s) that the interface has joined 
MTU  Maximum transmission unit of the interface
