To view the DHCPv6 database, use the following command:
(host)#show ipv6 dhcp database
You can also view the DHCPv6 database for a specific pool, use the following command:
(host) (config) #show ipv6 dhcp database [pool <pool-name>]
(host) (config) #show ipv6 dhcp database pool DHCPv6
To view the DHCPv6 binding information, use the following command:
(host)# show ipv6 dhcp binding
To clear all the DHCPv6 bindings, use the following command:
(host)# clear ipv6 dhcp binding
To view the DHCPv6 server statistics, use the following command:
(host)(config) #show ip dhcp statistics

Understanding ArubaOS Supported Network Configuration for
IPv6 Clients
ArubaOS provides wired or wireless clients using IPv6 addresses with services such as firewall functionality,
layer-2 authentication, and, with the installation of the Policy Enforcement Firewall Next Generation (PEFNG),
identity-based security. The Dell controller does not provide routing or Network Address Translation to IPv6
clients (see Understanding IPv6 Exceptions and Best Practices on page 150).
Supported Network Configuration
Clients can be wired or wireless and use IPv4 and/or IPv6 addresses. An external IPv6 router is recommended
for a complete routing experience (dynamic routing). You can use the WebUI or CLI to display IPv6 client
information.
On the controller, you can configure both IPv4 and IPv6 client addresses on the same VLAN.
Understanding the Network Connection Sequence for Windows IPv6 Clients
This section describes the network connection sequence for Windows Vista/XP clients that use IPv6 addresses,
and the actions performed by the AP and the controller.
1. The IPv6 client sends a Router Solicit message through the AP. The AP passes the Router Solicit message
from the IPv6 client through the GRE tunnel to the controller.
2. The controller removes the 802.11 frame and creates an 802.3 frame for the Router Solicit message.
a. The controller authenticates the user, applies firewall policies, and bridges the 802.3 frame to the IPv6
router.
b. The controller creates entries in the user and session tables.
3. The IPv6 router responds with a Router Advertisement message.
4. The controller applies firewall policies, then creates an 802.11 frame for the Router Advertisement message.
The controller sends the Router Advertisement through the GRE tunnel to the AP.
5. The IPv6 client sends a Neighbor Solicitation message.
6. The IPv6 router responds with a Neighbor Advertisement message.
7. If the DHCP is required to provide IPv6 addresses, the DHCPv6 process is started.
8. The IPv6 client sends data.
9. The controller removes the 802.11 frame and creates an 802.3 frame for the data.
