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@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 Copyright (C) 1999-2015 The FreeRADIUS server project and contributors. Issue: [root@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.
