Command Reference    IPv6 Commands 
 
REACH (Reachable): The switch is connected with the neighbor. In this state, the 
switch takes no additional action when sending packets to the neighbor. 
STALE: The reachable time of the neighbor expires. In this state, the switch takes no 
additional action; it only starts NUD (Neighbor Unreachability Detection) after a 
packet is sent to the neighbor. 
DELAY: A packet is sent to the neighbor in STALE state. If the STALE state changes 
to DELAY, DELAY will be changed to PROBE if no neighbor reachability notification 
is received within DELAY_FIRST_PROBE_TIME seconds (5s), the NS will be sent to 
the neighbor to start NUD. 
PROBE: The NUD is started to check the reachability of the neighbor. The NS 
packets are sent to the neighbor at the interval of RetransTimer milliseconds until the 
response from the neighbor is received or the number of the sent NSs hits 
MAX_UNICAST_SOLICIT(3). 
?: Unknown state. 
/R—indicate the neighbor is considered as a device 
/H: The neighbor is a host. 
Age 
The reachable time of the neighbor. ’-‘ indicates that the neighbor is always 
reachable. Note that the reachability of a static neighbor depends on the actual 
situation. ’expired’ indicates that the lifetime of the neighbor expires, and the 
neighbor is waits for the triggering of NUD.   
Asked 
The number of the NSs that are sent to the neighbor for the resolution of the link 
address of the neighbor.
