Description
When configuring Veritas Volume Replicator (VVR) on Windows OS, VVR performs various operations on different ports.These ports need to be open bidirectionally on all servers/cluster nodes in the Primary and Secondary sites, to ensure VVR remains in Active state and is able to send data traffic across sites.
Below is the list of ports required by VVR
VVR when configured for UDP/IP Protocol
Port Number |
Mode |
Description |
4145 |
UDP |
IANA approved port for heartbeat communication between the Primary and Secondary. |
8199 |
TCP |
IANA approved port for communication between the VRAS (vradmind) on the Primary and the Secondary. |
8989 |
TCP |
Communication between the vxrsyncd, which are used for differences-based synchronization |
2148 and 3207 |
TCP and UDP |
Veritas Enterprise Administrator (VEA) server connections |

Description |
4145 |
UDP |
IANA approved port for heartbeat communication between the Primary and Secondary. |
4145 |
TCP |
IANA approved port for TCP Listener port (on the remote server during data replication). |
8199 |
TCP |
IANA approved port for communication between the VRAS (vradmind) on the Primary and the Secondary. |
8989 |
TCP |
Communication between the vxrsyncd, which are used for differences-based synchronization |
2148 and 3207 |
TCP and UDP |
Veritas Enterprise Administrator (VEA) server connections |
Note: VVR requires a port range to transfer data packets across site. These are user-configurable ports from the dynamic ports range:49152-65535 and needs to be opened for TCP and UDP mode.
The default port range is 0-0 (any available port that the OS assigns from dynamic port range.) To display or change the existing port range, refer Page 300 onward of Volume Replicator Administrator's Guide - Windows
For more information regarding ports used by Infoscale, refer Page 408 onward of Volume Replicator Administrator's Guide - Windows
