5.2.5 Active protocols
You can control the type of traffic NNMi generates when communicating with devices in your network by using communication and monitoring configuration settings. Use the communication settings when firewalls in your infrastructure prohibit ICMP or SNMP traffic. Use monitoring settings to fine-tune protocol usage when you do not need a particular subset of data about devices. If either communication settings or monitoring settings disable a protocol for a device, NNMi does not generate that type of traffic to the device.
- Note
Disabling SNMP communication significantly compromises device management capabilities, such as troubleshooting, because the details of devices cannot be obtained.
Note whether each region or specific device needs to receive ICMP traffic.
You do not need to explicitly disable SNMP communication with devices for which you do not supply access credentials. By default, NNMi assigns those devices to the No SNMP device profile and monitors them using ICMP only.
If Web Agents are configured (in addition to SNMP Agents), NNMi can use additional protocols (for example, SOAP protocol for VMware environments).
