Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
The following table lists ports that SolarWinds NetFlow Traffic Analyzer uses to communicate with other devices and servers.
|80||TCP||World Wide Web Publishing Service||Bidirectional||Port used for web console and any other web servers.|
Port for outbound traffic if NetBIOS name resolution is turned on.
When NTA is trying to resolve the NetBIOS names of servers in their conversations, you may find a large amount of outbound UDP 137 traffic from the NTA collector to a number of external addresses. You can confirm the traffic by using the Flow Navigator to match the outbound connections to existing conversations.
This is normal behavior when NetBIOS is enabled. An easy way to demonstrate the behavior is to disable NetBIOS in NTA and watch all outbound connections terminate.
|161||TCP||SolarWinds Job Engine||Bidirectional||Port used for polling CBQoS-enabled devices.|
|1433||TCP||SolarWinds Collector Service||Outbound||Port used for communication between the NTA Flow Storage Database and the existing SQL server.|
|2055||UDP||SolarWinds Collector Service||Inbound||Port for receiving flows on any SolarWinds NTA collector.|
|5671||TCP||RabbitMQ||Bidirectional||Rabbit MQ messaging|
|17777||TCP||SolarWinds Information Service||Bidirectional||Port for sending and receiving traffic between SolarWinds NPM and other Orion Modules.|
|17778||HTTPS and TCP||SolarWinds Information Service||Bidirectional||Open to access the SolarWinds Information Service API and agent communication|
|17791||TCP||SolarWinds Agent||Bidirectional||Open for agent communication on any SolarWinds Orion server running Windows Server 2008 R2 SP1|
|Device-specific||Any port required by a specific device.|
