cmEthernetTrafficPortTransmitQL

Module: CM-FACILITY-MIB

OID (symbolic): CM-FACILITY-MIB::cmEthernetTrafficPortTransmitQL

OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.27.1.79

Node type: OBJECT-TYPE

Type: SSMQualityLevel

Access: read-only

Description: This object provides the Transmitted QL value for the Ethernet port. If the Ethernet port TransmitQL Mode is disabled, then the received QL value is not applicable. This object is only applicable for Synchronous Ethernet capable ports.

What is cmEthernetTrafficPortTransmitQL?

This object displays the Synchronous Ethernet (SyncE) Quality Level (QL) value being transmitted from this Ethernet port, indicating the quality/frequency stability of the clock derived from that port. It is only applicable to SyncE-capable ports and is a read-only value reflecting the transmitted clock quality. Timing synchronization engineers monitor this to ensure proper clock hierarchy and frequency accuracy across the network.
