D-PDD-DY-01: Dell PowerProtect Data Domain Deploy

Standard syslog message delivery from a Data Domain system relies on UDP port 514 by default. For the syslog server to receive the log messages sent from the Data Domain appliance, any firewall between the two systems must permit traffic on this port; otherwise, the syslog packets will be blocked and never reach the destination server. This is a basic network connectivity requirement independent of DDOS version, SNMP configuration, or system alert settings, which serve different purposes on the Data Domain system.
