msLineStatus

Module: ACMIB

OID (symbolic): ACMIB::msLineStatus

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.4.1.19

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: line status on the port: The msLineStatus is a bit map representation. It can represent multiple failures (alarms) if supported by the card.

NoAlarm should be set if and only if no other flag is set.

The various bit positions are: 1: NoAlarm 2: Loss of Signal

What is msLineStatus?

This read-only OID reports the current operational status of the multiserial line as a bitmap, indicating whether the line is operating normally or experiencing failures such as loss of signal. Network engineers monitor this to detect and diagnose port problems in real-time, particularly when troubleshooting connectivity issues. For example, a value of 1 means no alarm (the line is healthy), while a value of 2 indicates loss of signal on that port.
