How are network devices monitored in a collaboration network?

In Cisco collaboration deployments the network-management platform (for example, Cisco Prime Collaboration Assurance) periodically polls each voice, video, and infrastructure device with Simple Network Management Protocol (SNMP). The devices’ MIB objects expose operational status, interface statistics, fault counters, and performance data, enabling continuous, centralized monitoring and alerting.

A. CDP only advertises neighbor information; it is not designed for performance or fault monitoring.

B. Ping sweeps give basic reachability only and provide no detailed device statistics or traps.

C. Syslog is event-driven and supplemental; logs are pushed, not polled, and alone do not constitute proactive device monitoring.
