Module: DOCS-IETF-BPI2-MIB
OID (symbolic): DOCS-IETF-BPI2-MIB::docsBpi2CmtsSAMapRequests
OID (numeric): 1.3.6.1.2.1.126.1.2.1.1.10
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The value of this object is the number of times the CMTS has received an SA Map Request message from any CM. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is docsBpi2CmtsSAMapRequests?
This OID counts how many times cable modems have asked the CMTS to establish secure encryption connections (security association map requests) in a BPI2 security scheme. A rising count indicates active cable modem connections requesting security updates. A network operator would monitor this counter to detect anomalies, such as a flood of requests indicating an attack or a sudden stop indicating connectivity failures.
