Command
Step 4
show ipv6 interface
Example:
switch(config-if)# show ipv6 interface
Step 5
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
This example shows how to configure an IPv6 address:
switch# config t
switch(config)# interface ethernet 3/1
switch(config-if)# ipv6 address ?
A:B::C:D/LEN IPv6 prefix format: xxxx:xxxx/ml, xxxx:xxxx::/ml,
xxxx::xx/128
use-link-local-only
address
switch(config-if)# ipv6 address dc3:dc3::/64 eui64
This example shows how to display an IPv6 interface:
switch(config-if)# show ipv6 interface ethernet 3/1
Ethernet3/1, Interface status: protocol-down/link-down/admin-down, iod: 36

Configuring IPv6 Neighbor Discovery

You can configure IPv6 neighbor discovery on the router. The neighbor discovery protocol enables IPv6
nodes and routers to determine the link-layer address of a neighbor on the same link, find neighboring
routers, and keep track of neighbors.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command). You must first enable IPv6
on the interface.
