Example
The following example configures a static entry in the IPv6 neighbor discovery cache.
show ipv6 neighbors
The show ipv6 neighbors Privileged EXEC mode command displays IPv6 neighbor discovery cache information.
Syntax
show ipv6 neighbors {static | dynamic}[ipv6-address ipv6-address] [mac-address mac-address] [ethernet
interface-number | vlan vlan-id | port-channel number]
Parameters
•
static — Displays static neighbor discovery cashe entries.
• dynamic — Displays dynamic neighbor discovery cashe entries.
• ipv6-address — Displays the neighbor discovery cache information entry of a specific IPv6 address.
• mac-address — Displays the neighbor discovery cache information entry of a specific MAC address.
• ethernet interface-number — Displays the neighbor discovery cache information entry of a specific Ethernet
port interface.
• vlan vlan-id — Displays the neighbor discovery cache information entry of a specific VLAN.
• port-channel number — Displays the neighbor discovery cache information entry of a specific Port-channel
number interface.
Default Configuration
This command has no default setting.
Command Mode
Privileged EXEC mode.
User Guidelines
•
The associated interface of a MAC address can be aged out from the FDB table, so that the Interface field
can be empty.
• When an ARP entry is associated with an IP interface that is defined on a port or port-channel, the VLAN field
is empty.
• The possible neighbor cache states are:
– INCMP (Incomplete) — Address resolution is being performed on the entry. Specifically, a Neighbor
Solicitation has been sent to the solicited-node multicast address of the target, but the corresponding
Neighbor Advertisement 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 REACHABLE, no special action
takes place 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 STALE, no action takes place 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, and a packet was sent within the last
