Description: This indicates the current state of the Port Protocol Migration state machine.

This object will hold the value 'init' when the Protocol Migration state machine is in the INIT state, the value 'sendrstp' when the state machine is in the SEND_RSTP state, the value 'sendingrstp' when the state machine is in the SENDING_RSTP state, the value 'sendstp' when the state machine is in the SEND_STP state and the value 'sendingstp' when the state machine is in the SENDING_STP state.

What is nnRstDot1wPortMigSmState?

Reports the current state of this port's Protocol Migration state machine (init, sendrstp/sendingrstp, sendstp/sendingstp), showing whether the port is actively transitioning between RSTP and legacy STP BPDU formats.
