IPv6 Addressing Configuration
Configuring a Static IPv6 Address on a VLAN
Statically Configuring a Link-Local Unicast Address
Syntax: [no] ipv6 address fe80::< device-identifier > link-local
■
If IPv6 is not already enabled on the VLAN, this command
enables IPv6 and configures a static link-local address.
■
If IPv6 is already enabled on the VLAN, then this command
overwrites the current, link- local address with the speci
fied static address. (One link-local address is allowed per
VLAN interface.)
< device-identifier >: The low-order 64 bits, in 16-bit blocks,
comprise this value in a link-local address:
xxxx xxxx : xxxx xxxx : xxxx xxxx : xxxx xxxx
Where a static link-local address is already configured, a new,
autoconfigured global unicast addresses assignment uses the
same device identifier as the link-local address.
Notes: An IPv4 loopback address must be configured on the
switch before you use the
ipv6 address command to statically
configure an address. Refer to “Operating Notes” on page 4
14.
An existing link-local address is replaced, and is not
deprecated, when a static replacement is configured.
The prefix for a statically configured link-local address is
always 64 bits, with all blocks after fe80 set to zero. That is:
fe80:0:0:0.
After verification of uniqueness by DAD, a statically config
ured link-local address status is set to
preferred, with a perma
nent lifetime. (Refer to “IPv6 Address Deprecation” on page 3
24.)
For link-local addressing, the
no form of the static IPv6 address
command produces different results, depending on how IPv6
is configured on the VLAN:
4-12
