cmmOverrunErrors
Module: CT-CMMPHYS-MIB
OID (symbolic): CT-CMMPHYS-MIB::cmmOverrunErrors
OID (numeric): 1.3.6.1.4.1.52.4.1.1.18.1.3.1.32
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This object contains the number of HDLC overrun errors.
What is cmmOverrunErrors?
This read-only counter tracks the number of HDLC overrun errors, which occur when incoming data arrives faster than the receiving hardware buffer can process it. Admins monitor this as an indicator of a modem or host processing bottleneck under load. For example, a modem accumulating cmmOverrunErrors during high-throughput sessions might indicate its receive buffer or host interface can't keep pace with the negotiated line rate.
