SNMPv3 Context Addressing
SNMPv3 is not user configurable and user can use this option with any NMS. The radio SNMP management
interface supports SNMPv3/2 context addressing. The SNMv3 context addressing allows the user to use
secure SNMPv3 management while improving NMS performance.
A NMS (Network Management System) can access any remote radio directly by using its IP address or via
the base / master station SNMPv3 context addressing. The SNMPv3 context addressing can compress the
SNMPv3 management traffic OTA (Over The Air) to the remote station by up to 90% relative to direct OTA
SNMPv3 access to remote station, avoiding the radio narrow bandwidth traffic loading.
