Local Event Log | Juniper Networks G10 CMTS instruction

Features for Troubleshooting

Local Event Log

The local event log of the CMTS corresponds to the docsDevEventTable within the DOCS-CABLE-DEVICE-MIB (RFC 2669). This log can assist you with troubleshooting various issues. The OSSI specification defines required events that a CMTS must support. In addition, the G10 CMTS supports vendor-specific events.

To view the log, issue the show log cable command. Table 46 provides the correspondence between the display output fields and the DOCS-CABLE-DEVICE-MIB objects.
