Cisco IOS and IPv6 TACACS+

[Roger Wiklund]

I've just setup tac_plus server on a linux box. According to the
release notes this software supports IPv4 and IPv6.
I have it working using IPv4 to my 2800 running advipservice 12.4(22)T5.

However, on the 2800 I have no TACACS commands that relate to IPv6...

router(config)#tacacs-server host ?
  Hostname or A.B.C.D  IP address of TACACS server
  <cr>

I've looked at the Cisco Feature Navigator but cannot find anything re
TACACS+ and IPv6.

Anyone have TACACS+ running with IPv6 that can shed some light on this?

Thanks,
