Description: The value of tmnxCiscoHDLCOperState indicates the operational status of the Cisco HDLC protocol for this port.

What is tmnxCiscoHDLCOperState?

This object reports the current operational state (up, down, or testing) of the Cisco HDLC data link protocol on a port. Network operators monitor this to confirm that HDLC encapsulation is functioning correctly and to detect link failures or protocol state transitions. Unlike the physical link state, this reflects the behavior of the HDLC state machine.

Examples
