This example sends ping requests to an Ethernet device with IPv6 address
fe80::2d0:59ff:feb8:103c in VLAN 1. The device also responds the pings.

DESCRIPTION
This is the IPv6 address of the Switch or a neighboring device.
This is the MAC address of the neighboring device or itself.
This field displays whether the neighbor IPv6 interface is reachable. In
IPv6, "reachable" means an IPv6 packet can be correctly forwarded to a
neighbor node (host or router) and the neighbor can successfully receive
and handle the packet. The available options in this field are:
• reachable(R): The interface of the neighboring device is reachable.
(The Switch has received a response to the initial request.)
• stale(S): The last reachable time has expired and the Switch is
waiting for a response to another initial request. The field displays this
also when the Switch receives an unrequested response from the
neighbor's interface.
• delay(D): The neighboring interface is no longer known to be
reachable, and traffic has been sent to the neighbor recently. The
Switch delays sending request packets for a short to give upper-layer
protocols a chance to determine reachability.
• probe(P): The Switch is sending request packets and waiting for the
neighbor's response.
• invalid(IV): The neighbor address is with an invalid IPv6 address.
• unknown(?): The status of the neighboring interface can not be
determined for some reason.
• incomplete(I): Address resolution is in progress and the link-layer
address of the neighbor has not yet been determined (see RFC 2461).
The interface of the neighboring device did not give a complete
response.
This field displays the type of an address mapping to a neighbor interface.
The available options in this field are:
• other(O): none of the following type.
• dynamic(D): The IP address to MAC address can be successfully
resolved using IPv6 Neighbor Discovery protocol (See
Discovery Protocol (NDP)). Is it similar as IPv4 ARP (Address
Resolution protocol).
• static(S): The interface address is statically configured.
• local(L): A Switch interface is using the address.
This field displays the IPv6 interface.
This displays how long (hhhmmmsss) an address can be used before it
expires. If an address is manually configured, it displays permanent
(never expires).
