When experimenting with Cassandra I've observed that Cassandra listens to the following ports:
How does Cassandra use each of the ports listed?
553
What ports does Cassandra use? By default, Cassandra uses 7000 for cluster communication (7001 if SSL is enabled), 9042 for native protocol clients, and 7199 for JMX.
We can use netstat -atn to check whether port 9160 is active or not.
When experimenting with Cassandra I've observed that Cassandra listens to the following ports: TCP *:8080.
Cassandra uses a protocol called gossip to discover location and state information about the other nodes participating in a Cassandra cluster. Gossip is a peer-to-peer communication protocol in which nodes periodically exchange state information about themselves and about other nodes they know about.
@Schildmeijer is largely right, however port 7001 is still used when using TLS Encrypted Internode communication
So my complete list would be for current versions of Cassandra:
