Chapter 52 Neighbor Table

GS3700/XGS3700 Series User’s Guide

383

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.
