This is the MIB Module for the Diagnostic Log for DOCSIS-compliant Cable Modem Termination Systems (CMTS). The purpose of the Diagnostic Log is to prevent service interruptions by early detection of potential problems. It can also be used for fault management and for troubleshooting the cable network. The Diagnostic Log contains Cable Modems that show certain potential problematic behaviors, as determined by the CMTS. These detection criteria are defined as diagnostic triggers. The diagnostic trigger is an information filter to avoid inundating a management agent with data which is less meaningful as a function of size. There are 2 diagnostic triggers defined. Each trigger maintains a counter for each Cable Modem that is caught by that trigger. (1) Registration Trigger (2) Ranging Retry Trigger Copyright 1999-2007 Cable Television Laboratories, Inc.
