Radius Accounting for IPv6 Clients
Starting from ArubaOS 6.5, customers can monitor bandwidth usage by clients/hosts with IPv6 addresses over
Radius Accounting for IPv6 Clients (RADIUS) protocol. The Framed-IPv6-Address attribute is used in
accounting start, stop, and interim packets. A host can have multiple IPv6 addresses and all of them are
tracked to check the usage for billing purpose.
TACACS Over IPv6
ArubaOS provides support for TACACS authentication server over IPv6. You can configure the global IPv6
address as the host for TACACS authentication using CLI or WebUI.
In the CLI
(host)(config) #aaa authentication-server tacacs IPv6
(host)(TACACS Server "IPv6") #host <ipv6-address>
In the WebUI
1. Navigate to the Configuration > Security > Authentication > Servers page.
2. SelectTACACS Server to display the Server List.
3. Select the required server from the list to go to the TACACS server page.
4. To configure an IPv6 host for the selected server, specify an IPv6 address in the Host field.

DHCPv6 Server
The DHCPv6 server enables network administrators to configure stateful/stateless options and manage
dynamic IPv6 users connecting to a network. You can also configure domain name server using DHCPv6.
You can configure IPv6 pools with various configurations such as lease duration, DNS server, vendor specific
options, and user defined options using DHCPv6. You can also exclude IPv6 addresses from subnets.
Controller IPv6 addresses, VLAN interface IPv6 addresses, and DNS server addresses are excluded from use by
default.
Similar to DHCPv4, a DHCPv6 server pool is associated with a VLAN only through the IPv6 address configured
in that VLAN interface. A VLAN interface can have a maximum of three global unicast addresses, but only one
DHCPv6 pool.
DHCPv6 server supports stateless configuration of clients with options apart from the network addresses
described in RFC 3736.
Points to Remember
l Similar to IPv4, the default router configuration is not required for IPv6 pools as IPv6 compliant routers will
send RAs. The RA source address will be the default-gateway for the clients.
l ArubaOS does not support DHCPv6 relay and Hospitality feature on DHCPv6.
l IPv6 clients will not get a global IPv6 address if a previous DHCP binding exists.
