Default TCP/UDP Port Utilization
Port Number | Communication Type | Usage |
---|---|---|
TCP Port: | ||
20 to 21 |
|
Used by FTP server to transfer Bulkstats and in case of software upgrade, Config-backup, Config-update scheduler. |
22 |
|
Used by SSH or SFTP server for Config-backup, expect scripts. |
80 | WEM Client to WEM Server (Unsecured) | Used by Apache server for downloading the WEM applet and property files. This port is configurable. |
443 | WEM Client to WEM Server (Secured) | Used by Apache server for downloading the WEM applet and property files under secured connection. This port is configurable. |
14131 to 14132 | WEM Server to Chassis | Used for CORBA communication. These ports are configurable. |
15000 to 15002 |
|
Used for WEM client - server communication. WEM server receives requests on these ports from client. The chassis also sends notifications to the WEM server. The base port is configurable. |
15015 | NMS to WEM Server | Used by NorthBound server to receive requests on this port from NMS (3GPP standard CORBA NorthBound Interface). |
15017 | WEM Server to NMS | Used by CORBA Notification service for sending notifications to NMS (3GPP standard CORBA NorthBound Interface). |
40000 to 40010 | WEM Server to WEM Client | Used for WEM server - client communication. The notifications such as alarms, config changes, monitor protocol, real-time graphs are done by WEM server to WEM client. |
UDP Port: | ||
69 | Chassis to WEM Server | Used by TFTP server. If the WEM server machine has the chassis image/config and if they are to be loaded using TFTP, then this port will be used. |
162 | Chassis to WEM Server | Default port on which WEM receives SNMP traps from Chassis. This port is configurable. |
514 | Chassis to WEM Server | Used by Syslog server. WEM server machine may be configured to act as a syslog server for the Chassis logs. |
