MAC Address
This field displays the MAC address of the neighboring device.
Status
This field displays whether the neighbor IPv6 interface is reachable. In IPv6, “reachable”
means that an IPv6 packet can be correctly forwarded to a neighbor node (host or router)
and that the neighbor can successfully receive and handle the packet. The available options
for this field are:
Reachable: The neighboring device is reachable. (The EMG2926-Q10A has received a
response to the initial request.)
Stale: The last reachable time has expired and the EMG2926-Q10A is waiting for a
response to another initial request. The field also displays “Stale” when the EMG2926-Q10A
receives an unrequested response from the neighboring device.
Delay: The neighboring device is no longer known to be reachable, and traffic has been
sent to the neighbor recently. The EMG2926-Q10A delays sending request packets for a
short time to give upper-layer protocols a chance to determine reachability.
Probe: The EMG2926-Q10A is sending request packets and waiting for the neighbor’s
response.
Incomplete: Address resolution is in progress and the neighbor’s link-layer address has not
yet been determined. The neighboring device did not give a complete response.
