IPv6 coa isn't working having IPv6 NAS IP

[Samir Patel]

Hi Experts,

I need your help and expertise with pushing ipv6 coa on the 802.1x
sessions. UUT (Switch) and Freeradius are directly connected and can ping
each other.

Freeradius installed:
[root at ott-freerad-7a raddb]# radiusd -X
radiusd: FreeRADIUS Version 2.2.8, for host x86_64-unknown-linux-gnu, built
on Jul 15 2015 at 13:42:04

Issue:
[root at ott-freerad-7a raddb]# /usr/local/bin/radclient -x -t 20 -c 1 -p 20
-f /usr/local/etc/raddb/coa 2020::11:1700 coa cisco
radclient: Failed to find IP address for host 2020::11:1700: Success


COA push works for IPv4 NAS IP but shows above for IPv6 case. Really
appreciate your help with the issue. I am not sure if IPv6 coa push is
supported yet with 2.2.8 freeradius version.
