communication port used by NetVault

Netvault uses port 20031 - 20106
NDMP -10000

The Network Manager is configured to use port 20031 to open TCP and UDP sockets on a client. If this port is being used by another application, the NetVault Backup Service fails immediately after startup. When this occurs, you must change the default port for Network Manager.
To change the default port for Network Manager
1
Navigate to the <NetVault Backup home>\config directory, and open the file nvnmgr.cfg in a text editor.
2
Add the following lines to this file:
[network]
UdpPort=<port number>
TcpPort=<port number>
Set the same port number for both the TCP and UDP sockets. Ensure that the port is not in use by any other application. In a firewall-protected environment, ensure that the port is open and specified in the firewall settings for the client. For more information, see Configuring firewall settings.
3
Restart the NetVault Backup Service to apply the new settings.
4
Repeat steps 1–3 on the NetVault Backup Server and all clients.


The firewall settings enable communication with NetVault Backup Clients that are located outside the firewall. These settings provide the TCP/IP port specifications, which are used to establish data transfer channels, message channels, and broadcast channels through the firewall.
