On an SNMP-managed network, Cisco Unified Border Element can be the managed device and an agent. Which two elements are essential elements of Cisco Unified Border Element monitoring currently…

While CUBE can report active calls and bandwidth, 'Real-Time SIP Trunk Utilization' is a more general term; 'SIP Calls Arrival Rate Per Second' (B) is a more precise and commonly available SNMP counter for call load.

SNMP on Cisco Unified Border Element provides real-time metrics such as 'SIP Calls Arrival Rate Per Second,' which is an essential element for monitoring the current load and performance of the CUBE in processing new SIP calls.

'SIP Calls Holding Time' is typically derived from Call Detail Records (CDRs) or advanced reporting systems, not directly available as an essential, real-time SNMP counter on the CUBE device.

SNMP primarily provides current state and counters; 'Historical SIP Trunk Utilization' requires an external monitoring system to collect and process SNMP data over time, as the CUBE does not store historical data via SNMP.

'SIP Trunk Status' is a critical element available via SNMP on CUBE, allowing administrators to monitor the operational state (e.g., up or down) of configured SIP trunks, which is fundamental for ensuring connectivity and service availability.
