View

Parameters
ipv6-address: IPv6 address.
prefix-length: Prefix length of an IPv6 address, in the range of 1 to 128.
Description
Use the ipv6 address command to configure a site-local address or global unicast address manually
for an interface.
Use the undo ipv6 address command to remove the manually configured interface address.
By default, no site-local address or global unicast address is configured for an interface.
Note that:
An H3C S3100 Ethernet switch can have IPv6 unicast addresses configured on only one VLAN
interface. Only one global unicast address or one site-local address can be configured for an
interface.
You will remove all IPv6 addresses except the automatically configured link-local address if you
carry out the undo ipv6 address command without any parameter specified.
