60 IPv6 Interface Commands

show ipv6 neighbors

This command displays information in the IPv6 neighbor discovery cache.

Syntax

show ipv6 neighbors [vlan vlan-id ipv6-address]

•vlan-id- VLAN ID (Range: 1-4093)

•ipv6-address- The IPv6 address of a neighbor device. You can specify either a link-local or global unicast address formatted according to RFC 2373 “IPv6 Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal values. One double colon may be used in the address to indicate the appropriate number of zeros required to fill the undefined fields.

Default Setting

All IPv6 neighbor discovery cache entries are displayed.

Command Mode

Normal Exec - No command options are available.

Privileged Exec - All command options are available.

Example

The following shows all known IPv6 neighbors for this switch:

Console#show ipv6 neighbors
