The following table describes the labels in this display.
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.
Table 215 show ipv6 neighbor
LABEL DESCRIPTION
Address
This is the IPv6 address of the OLT or a neighboring device.
MAC
This is the MAC address of the neighboring device or itself.
S
This 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 OLT
has received a response to the initial request.)
•
stale (S)
: The last reachable time has expired and the OLT is waiting for a
response to another initial request. The field displays this also when the OLT receives
an un-requested 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 OLT delays sending request
packets for a short to give upper-layer protocols a chance to determine reach
ability.
•
probe (P)
: The OLT 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.
T
This 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 Neighbor Discovery Protocol (NDP) ). Is it
similar as IPv4 ARP (Address Resolution protocol).
•
static(S)
: The interface address is statically configured.
•
local (L)
: A OLT interface is using the address.
Interface
This displays the VLAN the IPv6 interface is on.
Expire
This displays how long (
hh h mm m ss s
) an address can be used before it expires. If an
address is manually configured, it displays
permanent
(never expires).
