Managing servers behind a firewall
HP SIM supports managing servers that are located behind a firewall when using the SSH, HTTPS, and
WBEM protocols. HP does not recommend the SNMP and DMI protocols for this purpose because they are
not secure protocols. The firewall must be configured to allow this traffic through the firewall. The following
ports are used:
• WBEM uses HTTPS over port 5989
• Web Agents use HTTPS over port 2381
• DTF uses SSH-2 over port 22
For a complete list of ports used by HP SIM, see the Understanding HP SIM Security white paper. This white
paper is available at http://www.hp.com/go/hpsim/.
