Cisco WLC 2504 setup #

Sending full IPv6 addresses to the RADIUS Accounting server #

The controller allows, for the RADIUS Accounting, to send the specific IPv6 address used by the client in the Framed-IPv6-Address attribute. Normally, only the IPv6 prefix is sent in Framed-IPv6-Prefix.

With the periodic updates, a single accounting packet will list all IPv6 addresses that the controller has recorded for the client at the time.

This option is not available in the GUI, only via the CLI (e.g. SSH):

config wlan radius_server acct framed-ipv6 both
