Use the OpsCenter ports reference for guidance when configuring firewall rules. The ports reference provides details for the default port numbers used by OpsCenter, Lifecycle Manager, and DataStax Agents. The ports are set to defaults. The configuration options and file or UI locations for overriding port defaults are indicated in the description column of the following table.

Table 1. OpsCenter Ports
Port/Protocol Source Destination Description
8888/TCP Management workstation OpsCenter server OpsCenter web-based user interface. The opscenterd daemon listens on this port for HTTP requests coming directly from the browser.

Configure with the [webserver] port option in opscenterd.conf.

DSE nodes OpsCenter server LCM Meld configs and job-events. The opscenterd daemon listens on this port for configuration requests and job-events coming from DSE nodes during the provisioning and installing agent processes.

Configure with the [webserver] port option in opscenterd.conf.

7199/TCP DataStax agent DSE JMX monitoring port. Each agent opens a JMX connection to its local node (the DataStax Enterprise process listening on this port). The JMX protocol requires that the client then reconnect on a randomly chosen port (1024+) after the initial handshake.
Note: It is not necessary to set this local port for firewall purposes.

Configure with the [jmx] port option in cluster_name.conf, or if necessary, in address.yaml.

8443/TCP Management workstation OpsCenter server SSL. The port on which to serve SSL traffic. The opscenterd daemon listens on this port for HTTPs requests being redirected from port 8888. The SSL port is the alternative UI/API port when SSL is enabled. When SSL is on, 8888 redirects to 8443 and serves no content.

Configure with the [webserver] ssl_port in opscenterd.conf.

DSE nodes OpsCenter server LCM Meld configs and job-events. The opscenterd daemon listens on this port for configuration requests and job-events coming from DSE nodes during the provisioning and installing agent processes.

Configure with the [webserver] ssl_port in opscenterd.conf.

25/TCP (non-SSL) 465 (SSL) OpsCenter server SMTP server SMTP for email alerting. See Enabling SMTP email alerts.

Configure in one or more uniquely named config_location/event-plugins/email.conf files.

9042/TCP OpsCenter server DSE Native transport: The native transport port for the cluster configured in native_transport_port in cassandra.yaml. Port 9042 must be open from the OpsCenter server to all DSE nodes.
Configure with the cql_port option in cluster_name.conf.
Note: The port must also be open on a storage cluster. Configure with the [storage_cassandra] cql_port.
DataStax agent DSE The agent and opscenterd must be able to connect to the native_transport_port.
Note: It is not necessary to set this local port for firewall purposes.
61619/TCP OpsCenter server OpsCenter server OpsCenter stomp port. A port used by the Stomp service for internal communications on the OpsCenter server.
Note: It is not necessary to set this local port for firewall purposes.

Configure with the [agents] incoming_port in opscenterd.conf.

61620/TCP DataStax agents OpsCenter server Agent communications over Stomp. The opscenterd daemon listens on this port for TCP traffic coming from the agents.

Configure with the stomp_port option in address.yaml.

61621/TCP OpsCenter Server DataStax agents DataStax agent port for DataStax agents http/https service. The agents listen on this port for TCP traffic initiated by OpsCenter. Depending on the OpsCenter and Agent configuration, traffic is either http or https protocol.

Configure with the [agents] api_port in cluster_name.conf or in address.yaml.

22/TCP OpsCenter server LCM deployment targets and agent install deployment targets SSH. Standard SSH (Secure Shell) port. Lifecycle Manager and the agent installation process log into target nodes over SSH.
Configured with the [agents] ssh_port in opscenterd.conf.
Note: The SSH Management Port can be overridden at the cluster, datacenter, or node level in the Clusters workspace of Lifecycle Manager.
443/TCP OpsCenter server OpsCenter download host opscenter.datastax.com OpsCenter Definitions. OpsCenter definition files allow updating the support of DSE versions without requiring upgrading to an updated version of OpsCenter itself. See Updating and configuring definitions files properties.

Configure with the [definitions] download_port in opscenterd.conf.

389/TCP and UDP OpsCenter server LDAP or AD server LDAP or AD. Default port for non-SSL LDAP and AD.

Configure with the [ldap] server_port option in opscenterd.conf.

636/TCP and UDP OpsCenter server LDAP or AD server LDAP or AD SSL. Default port for SSL traffic to LDAP and AD.

Configure with the [ldap] server_port option in opscenterd.conf.

7080/TCP OpsCenter server DSE Spark Jobs UI. Port at which the Spark jobs UI is exposed. Configure the port to view Spark Master nodes in the Spark console access from the Node Details dialog within OpsCenter.

Configure with the [spark] master_http_port option in cluster_name.conf.

For information about defining a datacenter in OpsCenter LCM for Spark workloads, see Adding a datacenter. For information about using Spark with the DataStax Enterprise platform, see analyzing data using Spark.

7081/TCP Management workstations OpsCenter server Spark Jobs UI. OpsCenter proxies the Spark Jobs UI.

Configure with the [spark] base_master_proxy_port option in opscenterd.conf.

162/UDP OpsCenter server SNMP Manager SNMP. Listening port on the SNMP manager to receive SNMP traps.

Configure with one or more uniquely named config_location/event-plugins/snmp.conf files.

2003/TCP DataStax agent Graphite server Graphite (labs feature in OpsCenter). Port to which OpsCenter sends Graphite metrics.

Configure with the [labs] graphite_port option in cluster_name.conf or address.yaml if necessary.

3128/TCP LCM targets Third-party proxy server Package proxy port in LCM for DSE installs. Default port for the Lifecycle Manager package proxy for downloading software installation packages for DataStax Enterprise and its dependencies such as Java.

Configure in the Package Proxy section of the Config Profile in the Lifecycle Manager UI.
