A management agent can be an SNMP agent or a VR agent. The following root-cause problem is diagnosed for management agent:

NotResponding: Indicates that a management agent is not responding to SNMP requests, but that the host system is responding to ICMP and ICMPv6 pings. Typically, this situation is caused by the use of an incorrect community string (SNMPv1 or v2c), or the agent might be hung.


By default, the SNMP Agent NotResponding is generated after three polling cycles. It is not generated after one unsuccessful poll to avoid false alerts.

The event used to diagnose management agent NotResponding is management agent Unresponsive.
