VLAN Name

IPv6 Status

For the indicated VLAN, shows whether IPv6 is disabled (the default) or enabled.

See “Configuring IPv6 addressing” (page 12).

Address Origin

Autoconfig

The address was configured using SLAAC. In this case, the interface identifier

for global unicast addresses copied from the current link-local unicast

address.

DHCP

The address was assigned by a DHCPv6 server. Addresses having a DHCP

origin are listed with a 128-bit prefix length.

IPv6 Address/Prefix Length

Lists each IPv6 address and prefix length configured on the indicated VLAN.

Address Status

Tentative

DAD has not yet confirmed the address as unique, and it is not usable for

sending and receiving traffic.

Preferred

The address has been confirmed as unique by DAD and usable for sending

and receiving traffic. The Expiry time shown for this address by the show

ipv6 vlan vid command output is the preferred lifetime assigned to

the address. See “Address lifetimes” (page 28).

Deprecated

The preferred lifetime for the address has been exceeded, but there is time

remaining in the valid lifetime.

Duplicate

Indicates a statically configured IPv6 address that is a duplicate of another

IPv6 address that already exists on another device belonging to the same

VLAN interface. A duplicate address is not used.

Example 6 (page 23) shows the output on a switch having IPv6 enabled on one VLAN.
