IPv6 Address

IPv6 address of neighbor or interface.

Age

Time (in minutes) since the address was confirmed to be reachable. A hyphen (-) indicates a static entry.

Link-layer Addr

MAC address. If the address is unknown, a hyphen (-) is displayed.

State

The state of the neighbor cache entry. Following are the states for dynamic entries in the IPv6 neighbor discovery cache:

•INCMP (Incomplete)—Address resolution is being performed on the entry. A neighbor solicitation message has been sent to the solicited-node multicast address of the target, but the corresponding neighbor advertisement message has not yet been received.

•REACH (Reachable)—Positive confirmation was received within the last ReachableTime milliseconds that the forward path to the neighbor was functioning properly. While in REACH state, the device takes no special action as packets are sent.

•STALE—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. While in STALE state, the device takes no action until a packet is sent.

•DELAY—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. A packet was sent within the last DELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation is received within DELAY_FIRST_PROBE_TIME seconds of entering the DELAY state, send a neighbor solicitation message and change the state to PROBE.

•PROBE—A reachability confirmation is actively sought by resending neighbor solicitation messages every RetransTimer milliseconds until a reachability confirmation is received.

•????—Unknown state.

Following are the possible states for static entries in the IPv6 neighbor discovery cache:

•INCMP (Incomplete)—The interface for this entry is down.

•REACH (Reachable)—The interface for this entry is up.

Note Reachability detection is not applied to static entries in the IPv6 neighbor discovery cache; therefore, the descriptions for the INCMP (Incomplete) and REACH (Reachable) states are different for dynamic and static cache entries.

Interface

Interface from which the address was reachable.

Entries

Total number of ND neighbor entries in the ND cache.

High-Water

Maximum amount (so far) of ND neighbor entries in ND cache.

Gleaned

Number of ND neighbor entries gleaned (that is, learned from a neighbor NA or other ND packet).

Scavenged

Number of stale ND neighbor entries that have timed out and been removed from the cache.

Entry States¹

Number of ND neighbor entries in each state.

Resolutions (INCMP)

Statistics for neighbor resolutions attempted in INCMP state¹ (that is, resolutions prompted by a data packet). Details about the resolutions attempted in INCMP state are follows:

•Requested—Total number of resolutions requested.

•Timeouts—Number of timeouts during resolutions.

•Resolved—Number of successful resolutions.

•Failed—Number of unsuccessful resolutions.

•In-progress—Number of resolutions in progress.

•High-water—Maximum number (so far) of resolutions in progress.

•Throttled—Number of times resolution request was ignored due to maximum number of resolutions in progress limit.

•Data discards—Number of data packets discarded that are awaiting neighbor resolution.

Resolutions (PROBE)

Statistics for neighbor resolutions attempted in PROBE state (that is, re-resolutions of existing entries prompted by a data packet):

•Requested—Total number of resolutions requested.

•Timeouts—Number of timeouts during resolutions.

•Resolved—Number of successful resolutions.

•Failed—Number of unsuccessful resolutions.

¹ Reachability detection is not applied to static entries in the IPv6 neighbor discovery cache. A static entry is always in the REACH (Reachable) state unless the associated interface is down or IPv6 is not enabled on the interface.

¹ The following example shows the ND cache limit on port-channel 1.11:

1 Router# show ipv6 neighbor port-channel1.11

1 Interface Port-channel1.11, entries 4, static 0, limit 4, ignored 0

1 IPv6 Address                     Age  Link-layer Addr  State   Interface

1 2001:2::93                       0    aabb.cc00.5d02   REACH   Po1.11

1 FE80::A8BB:CCFF:FE00:5D02        0    aabb.cc00.5d02   DELAY   Po1.11

1 2001:2::92                       0    aabb.cc00.5d01   STALE   Po1.11
