CISCO-GNSS-MIB
AI MIB Summary
The CISCO-GNSS-MIB enables monitoring of GNSS receiver hardware presence, module lock status, and slot states on Cisco network devices to verify satellite signal acquisition for precise timing synchronization. This module provides critical visibility into the integrity of the clock source used for telecom network synchronization, supporting both hierarchical and flat timing architectures.
The MIB module for GNSS
Overview of GNSS
GNSS (Global Navigation Satellite System) is used to describe the collection of Satellite Systems that are operating or planned. There are many Satellite constellation systems already available. These constellations allows ground base GNSS receivers to receive radio signals from these satellites and recover accurate location and time. Location and Time both are primary uses cases for many technologies, specifically for Telecom Network Operator, Timing use case is very important. Typical telecom networks synchronization works in a hierarchal manner where core network is connected to stratum 1 clock and the clock is distributed along the network in a tree like structure. With GPS receiver however, clocking can be changed to a flat architecture where access networks can directly take clock from satellites in sky using on-board GPS chips.
