serialPortEnabled
Module: CM-SYSTEM-MIB
OID (symbolic): CM-SYSTEM-MIB::serialPortEnabled
OID (numeric): 1.3.6.1.4.1.2544.1.12.2.1.3.5
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This provides ability to enable/disable the Serial Port on the system.
What is serialPortEnabled?
This TruthValue enables or disables the physical serial console port on the system. Disabling it removes local out-of-band CLI access through the craft port, which an admin might do to close off a potential local-access vector in a secured facility. For example, a data-center operator could set serialPortEnabled to false once remote SSH management is confirmed working, preventing anyone with physical port access from getting a console session.
