Ports for outbound traffic

The following are the ports that are used by the DD system for outbound traffic.

Table 1. Ports Used by DD System for Outbound Traffic
Port	Service	Note
TCP 20	FTP	Port is used for data only if FTP is enabled (run adminaccess show on the DD system to determine if this is the case).
TCP 25	SMTP	Used by the DD system to send email autosupports and alerts.
UDP/TCP 53	DNS	Port is used by DD system to perform DNS lookups when DNS is configured. Run net show dns to review DNS configuration.
TCP 80	HTTP	Used by DD system for uploading log files to DD Support via the support upload command.
UDP 123	NTP	Used by the DD system to synchronize to a time server.
UDP 162	SNMP (Trap)	Used by the DD system to send SNMP traps to SNMP host. Use snmp show trap-hosts to see destination hosts and snmp status to display service status.
TCP 443	HTTPS	Port is used for communicating with Object store (S3).
UDP 514	Syslog	Used by the DD system to send syslog messages, if enabled. Use 'log host show' to display destination hosts and service status.
TCP 2051	Replication / OST / Optimized Duplication	Used by DD system only if replication is configured. Use replication show config to determine if this is the case.
TCP 3009	SMS (System Management)	Port is used for managing a system remotely using Web Based GUI DD EM (DD Enterprise Manager). This port cannot be modified. This port is only used on DD systems running DDOS 4.7.x or later. This port will also need to be opened if you plan to configure replication from within the DD GUI interface, as the replication partner needs to be added to the DD Enterprise Manager.
TCP 5001	iPerf	Port is default used by iperf.To change the port, it requires -p option from se iperf or port option from the net iperf command. And the remote side must listen on the new port.
TCP 5002	Congestion-checker	Port is default used by congestion-checker, when it runs iperf. To change the port the new port needs to be specified in the port option of the net congestion-check command. The remote side must also be able to listen on the new port. It is available only for DDOS 5.2 and above.
TCP 27000	Avamar client communications with Avamar server	Avamar client network hosts.
TCP 27000	Avamar server communications with Replicator target server (Avamar proprietary communication)	Required if server is used as replicator source.
