Configuring Transmission Methods
Procedure
1. On your web user interface, go to Network > Advanced > Port Link.
For VP59, go to Network > Advanced > Port Link.
2. Configure and save the following settings:
Parameter Description Configuration Method
WAN Port Link
(WAN Port Link/PC Port Link)
Specify the network speed and
the duplex mode for the system.
Note: the default value is Auto.
The network speed and duplex
mode you select must be
supported by the switch. PC
Port Status is only applicable to

Restricting Reserved Ports
By default, the VCS endpoint communicates through TCP and UDP ports from 50000 to 51000 for the
video, the voice, the presentation, and the camera control. The VCS endpoint uses only a small number
of these ports during a call. The specific number of the port depends on the number of participants in the
call, the protocol used, and the number of ports required for the type of call (video or voice). To minimize
the number of UDP and TCP ports that are available for communication, you can restrict the ports range.
