ipv6 neighbor
This command configures a static entry in the IPv6 neighbor discovery cache. Use
the no form to remove a static entry from the cache.
Syntax
ipv6 neighbor ipv6-address vlan vlan-id hardware-address
no ipv6 mtu
• ipv6-address - The IPv6 address of a neighbor device that can be reached
through one of the network interfaces configured on this switch. 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.
• vlan-id - VLAN ID (Range: 1-4093)
• hardware-address - The 48-bit MAC layer address for the neighbor device.
This address must be formatted as six hexadecimal pairs separated by
hyphens.

Command Usage
• Address Resolution Protocol (ARP) has been replaced in IPv6 with the
Neighbor Discovery Protocol (NDP). The ipv6 neighbor command is similar
to the mac-address-table static command (page 50-1) that is implemented
using ARP.
• Static entries can only be configured on an IPv6-enabled interface.
• The switch does not determine whether a static entry is reachable before
placing it in the IPv6 neighbor discovery cache.
