Example

HP-Switch# show ipv6 source-interface detail

Protocol : Radius

Admin Policy : Outgoing Interface

Oper Policy : Outgoing Interface

Source IPv6 Interface : vlan- 1

Source IPv6 Address : 192.168.1.2

Source Interface State : N/A

Shows the source IPv6 configuration, status or detailed information. In this example the command

is invoked without parameters therefore it shows the configuration information for all protocols.

• If status is specified the operational status information will be shown.

• If detail is specified the detailed operational status information will be shown.

• If protocol-ID is specified the information only relevant to the specified protocol will be

shown.

Enabling IPv6 with an automatically configured link-local address

Syntax:

[no] ipv6 enable

If IPv6 has not already been enabled on a VLAN by another IPv6 command option

described in this chapter, this command enables IPv6 on the VLAN and automatically

configures the VLAN's link-local unicast address with a 64-bit EUI-64 interface

identifier generated from the VLAN MAC address.

NOTE: Only one link-local IPv6 address is allowed on the VLAN interface.

Subsequent static or DHCP configuration of another link-local address overwrites

the existing link-local address.

A link-local address always uses the prefix fe80:0:0:0.

With IPv6 enabled, the VLAN uses received RAs to designate the default IPv6 router.

See “Default IPv6 router” (page 35).

After verification of uniqueness by DAD, a link-local IPv6 address assigned

automatically is set to the preferred status, with a "permanent" lifetime.

Default: Disabled

The no form of the command disables IPv6 on the VLAN if no other IPv6-enabling

command is configured on the VLAN. See “About disabling IPv6 on a VLAN”

(page 30).

Viewing currently configured IPv6 unicast addresses

To view the current IPv6 enable setting and any statically configured 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 the VLAN.)

• show ipv6 tunnel tunnel-id (Lists IPv6 addresses configured on the tunnel.)

For more information, see “Viewing the current IPv6 addressing configuration” (page 21).
