deny ipv6 any any sequence 20
IPv6 access list a2

deny ipv6 any any sequence 20

and PC connected to it and PC get authenticated in radius assigned VLAN, on switchover, first
packet come from PC will trigger the security violation.

redundancy switch-over.

HSRP and currently in HSRP Active state.
Workaround: None. (CSCsi40980)
