What is tnIfRedundActivePort?

This read-write value reports which port (by ifIndex) is currently active as the primary link in a redundant pair, applicable only when redundancy is enabled. Admins check this to see, at a glance, whether a failover has already occurred and traffic is currently riding the secondary port.
