What is h3cDot11RRMHistoryChgReason?
This OID reports a bitmask indicating why a wireless radio changed channel or transmit power. Each bit flag represents a specific trigger: coverage gaps, radar detection, excessive retransmission, packet loss, or interference. Engineers use this to understand whether power adjustments were automatic responses to poor signal, interference, or regulatory compliance.
