IPv6 Addressing Configuration
Configuring a Static IPv6 Address on a VLAN
To view the currently configured static IPv6 addresses per-VLAN, use show run .
To view all currently configured IPv6 unicast addresses, use the following:
■
show ipv6 (Lists IPv6 addresses for all VLANs configured on the switch.)
■
show ipv6 vlan < vid >
(Lists IPv6 addresses configured on
VLAN < vid >
.)
For more information, refer to “View the Current IPv6 Addressing Configura-
tion” on page 1-17.
Operating Notes
■
With IPv6 enabled, the switch determines the default IPv6 router for the
VLAN from the router advertisements it receives. (Refer to “Router Access
and Default Router Selection” on page 1-23.)
■ If DHCPv6 is configured on a VLAN, then configuring a static global
unicast address on the VLAN removes DHCPv6 from the VLAN's config-
uration and deletes the DHCPv6-assigned global unicast address.
■
Note that for a statically configured global unicast address to be routable,
a gateway router must be transmitting router advertisements on the
VLAN.
■ If an autoconfigured global unicast address already exists for the same
subnet as a new, statically configured global unicast address, the statically
configured address is denied. In the reverse case, you can add an auto-
config command to the VLAN configuration, but it will not be imple-
mented unless the static address is removed from the configuration.
< prefix-length >:
Specifies the number of bits in the network
prefix. If you are using the
eui-64
option, this value must be 64.
eui-64:
Specifies using the Extended Unique Identifier format
to create a device identifier based on the VLAN MAC address.
Refer to “Disabling IPv6 on a VLAN” on page 1-12.
After verification of uniqueness by DAD, the lifetime of a
statically configured IPv6 address assigned to a VLAN is set
to permanent, and is configured as a preferred address. (Refer
to “View the Current IPv6 Addressing Configuration” on
page 1-17.)
The
no
form of the command erases the specified address and,
if no other IPv6-enabling command is configured on the VLAN,
disables IPv6 on the VLAN. (Refer to “Disabling IPv6 on a
VLAN” on page 1-12.)
