Deployment recommendations

This topic contains recommendations for deploying BMC Network Automation.

Initial configurations

This section describes the initial configurations available in BMC Network Automation.

Configuring database backups

BMC Network Automation includes a database backup script when using the embedded PostgreSQL database. This makes database management more convenient. See Maintaining-the-database for location and usage instructions.

Configuring remote device agents

BMC Network Automation remote device agents are useful when network devices have overlapping IP addresses or are located in a secure location that is not accessible from the BMC Network Automation application server. Remote device agents are installed on Linux or Microsoft Windows host computers. See Installing-the-remote-device-agent-on-Windows and Installing-the-remote-device-agent-on-Linux for information about configuring them.

Configuring syslog

BMC Network Automation has a built-in syslog receiver. Syslog messages that are received can be used to trigger a snapshot of a network device, be included in change summary reports, and can be correlated with other events to trigger a job. BMC Network Automation can also be configured to receive syslog events from a relay instead of directly from the network device. This comes in handy if the customer has an existing syslog server that they want to continue using or if another layer of filtering of syslog messages is required before forwarding to BMC Network Automation.

For information about configuring syslog, see Configuring-existing-syslog-servers-to-forward-events.

Configuring device import

BMC Network Automation does not have an embedded means of discovering new devices on the network. The primary means of getting devices into BMC Network Automation is through device import. BMC Network Automation has a number of out-of-the-box device import adapters that enable importing from common discovery tools like BMC Atrium Discovery and Dependency Mapping, Entuity Eye of the Storm, HP Network Node Manager, and CSV. See Understanding-device-import-formats and Managing-device-import-tasks.

Security considerations

This section describes security considerations for BMC Network Automation.

Role-based access control

See Managing-access.

Subjecting jobs to approval

Select the Enable Job Approval for Actions system parameter and then all actions that must require network operations and/or BMC Remedy Action Request (AR) System approvals. For more information, see Approving-jobs.

You also must define the Job Approval Types, including BMC Remedy AR System approval, under Admin > Job Approval Types. For more information, see Managing-job-approval-types.

Port usage

The following table describes port usage for BMC Network Automation.

Use	Default port number	Configuration details
Syslog	514	The system can receive syslog events directly from the network devices on port 514 (default). You can change this default port under Admin > Device Agent.
TFTP	69	TFTP/FTP/SCP services are configured for the local (default) and any remote device agents under Admin > Device Agents.
Telnet	23	This port is set in the global.properties.imported file. # Port number where telnet connections are made by BCA-Networks. # Default = 23 # #telnetConnectionPort=23
Device agent	1099	The device agent uses a single secure port (default 1099) to communicate with the application server. This port can be set during the Device Agent installation in the RMI Port Number field. For silent installations, you can set it the parameters file: ##### Default - 1099. -J BCAN_DEVICE_AGENT_RMI_PORT=1099
SCP/SSH	22	This port is set in the global.properties.imported file. # Port number where SSH connections will be made by BCA-Networks. # Default = 22 # #sshConnectionPort=22
HTTP	80	The http and https ports can be set during the application server installation in the Web Server Information panel. For silent installations, you can set it in the parameters file: ##### Default - 80. -J BCAN_HTTP_PORT_NUMBER=80
HTTPS	443	The http and https ports can be set during the application server installation in the Web Server Information panel. For silent installations, you can set it in the parameters file: ##### Default - 443. -J BCAN_HTTPS_PORT_NUMBER=443 The port number setting is made in the global.properties.imported file. # # Port number used to connect to http oriented devices. # Default = 80 # #httpConnectionPort=80 # # Port number used to connect to https oriented devices. # Default = 443 # #httpsConnectionPort=443
PostgreSQL	15432	Port opened by the embedded PostgreSQL database server during installation. The port number is set and used in the catalina.properties, database.properties, and pgpass.conf files, and the setenv_db script.
SSH proxy	4000	Port to access application server's command line interface. The port number is set in the global.properties file. # # The listen port for the ssh proxy daemon. # Default = "4000" # #sshProxyPort=4000
