display snmp-agent statistics
Usage Guidelines
- The NMS acts as a manager to send an SNMP Request message to the SNMP agent.
- The SNMP agent searches the MIB on the device for the required information and sends an SNMP Response message to the NMS.
- When the trap triggering conditions are met, the SNMP agent sends a trap to the NMS to report the event occurring on the device. In this manner, the network administrator can process the event occurring on the network in time.
The display snmp-agent statistics command analyzes the statistics about SNMP messages and obtains information about the communication between the SNMP agent and the NMS for fault location.
If large number of messages are received in short period, a great number of CPU resources are occupied. The number of received messages depends on the frequency at which the NMS sends the Request messages.
