Table 256 Management > IPv6 Neighbor Table (continued)
LABEL
DESCRIPTION
Status
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. The interface of the neighboring device did not
give a complete response.
Type
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.
•
local (L): A Switch interface is using the address.
•
dynamic (D): The IP address to MAC address can be successfully resolved using IPv6
Neighbor Discovery protocol. Is it similar as IPv4 ARP (Address Resolution protocol).
•
static (S): The interface address is statically configured.
