vrport [-a | -r] data [port | portlow-porthigh [,port...]]
vrport heartbeat [port]
vrport vradmind [port]
vrport vxrsyncd [port]
VVR uses the UDP and TCP transport protocols to communicate between the Primary and Secondary.
VVR exchanges three types of message between the Primary and Secondary: heartbeat, data and administrative control.
The heartbeat messages are transmitted using the UDP protocol on the IANA approved 4145 UDP Port number. VVR can use either the UDP transport protocol or the TCP transport protocol to exchange data messages. VVR uses UDP Anonymous ports for data replication between Primary and the Secondary if the network protocol is UDP. VVR uses IANA approved 4145 TCP port number for TCP listener port on the Secondary and TCP Anonymous ports on the Primary for data replication if the network protocol is TCP.
VVR uses IANA approved 8199 TCP port for communication between the vradmind daemons on the Primary and the Secondary. vradmind server provides administration of VVR objects in a distributed environment. VVR uses 8989 TCP port number for communication between the vxrsyncd daemons on the Primary and the Secondary.
Use vrport to display, change or set the port numbers used by VVR. You may have to change the port numbers to resolve a port number conflict with other applications, to configure VVR to work in a firewall environment when using UDP network protocol by restricting the number of ports to replicate data between the Primary and the Secondary.
The action performed by vrport depends on the specified keyword operand(s).
When invoked with no arguments, vrport displays the port number(s) used for heartbeat, data, vradmind and vxrsyncd communication between the Primary and Secondary on the standard output.
With the port number(s) or range specified, restricts VVR to use the ports or list of ports specified for data replication.
If the -a flag is specified, the vrport data command appends the given port numbers(s) or range to the existing port number(s) or range to be used for data replication.
If the -r flag is specified, the vrport data command removes the given port number(s) or range from the existing port number(s) for data replication.
You need to execute /usr/sbin/vxnetd, and pause and resume all RLINKs for VVR to use the new port information.
With the port argument specified, sets the UDP port number to exchange heartbeat messages. Use the vradmin changeip command to update the RLINKs with the new port information. To have VVR use the new port number, enter the command /usr/sbin/vxnetd stop followed by /usr/sbin/vxnetd.
With the port argument specified, sets the TCP port number to be used by the vradmind daemons. The new port is used when the vradmind process is restarted.
With the port argument specified, command sets the TCP port number to be used by the vxrsyncd daemons. The new port is used when the vxrsyncd process is restarted.
