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.
| 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. |
