Configuring services
You can configure and enable the following services on CMC:
• CMC serial console — Enable access to CMC using the serial console.
• Web Server — Enable access to CMC web interface. Disabling the web server also disables Remote RACADM.
• SSH — Enable access to CMC through firmware RACADM.
• Telnet — Enable access to CMC through firmware RACADM
• Remote RACADM — Enable access to CMC using RACADM.
• SNMP — Enable CMC to send SNMP traps for events.
• Remote Syslog — Enable CMC to log events to a remote server. To use this feature, you must have an Enterprise license.
NOTE:
When modifying CMC service port numbers for SSH, Telnet, HTTP, or HTTPS, avoid using commonly used ports
by OS services such as port 111. See Internet Assigned Numbers Authority (IANA) reserved ports at http://
www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml.
CMC includes a web server that is configured to use the industry-standard SSL security protocol to accept and transfer encrypted data
from and to clients over the Internet. The web server includes a Dell self-signed SSL Digital Certificate (Server ID), and is responsible for
accepting and responding to secure HTTP requests from clients. This service is required by the web interface and remote RACADM CLI
tool for communicating with CMC.
If the web server resets, wait at least one minute for the services to become available again. A web server reset usually happens as a
result of any of the following events:
• Network configuration or network security properties are changed through the CMC web user interface or RACADM.
• Web server port configuration is changed through the web user interface or RACADM.
• CMC is reset.
• A new SSL server certificate is uploaded.
NOTE: To modify service settings, you must have the Chassis Configuration Administrator privilege.
