The value of the object tIPv6FilterChainToSystemFilter specifies whether this filter policy is chained to the active IPv6 system filter policy. The active IPv6 system filter policy is defined as a row in tFilterSystemFilterTable that have the value of the object tFilterSystemFilterType set to 'fltrtypeselIpv6(4)'. The value 'true(1)' means this filter policy is chained to the active IPv6 system filter policy. The system filter policy's rules are executed first before any rules of this filter policy are executed. The value of this object can be set to 'true(1)' only when the scope of this policy (value of the object tIPv6FilterScope) is 'exclusive(1)' or 'template(2)'. The value 'false(2)' means this filter policy is not chained to the system filter policy.
