LAN Port Specific Options
Option Function Comments
4 and 14 gateway:
Set the IP address of
the default gateway.
• Gateway values must be set on the streaming port otherwise
no streaming status is available in the HTML network
interface. The default gateway must be on the same subnet
as the port to which it is assigned.
Manually enter the gateway address for the port; use
no leading zeroes. For example: 192.168.0.1 is valid,
192.168.000.001 is not valid.
NOTE: Only one default gateway is supported. Once a
gateway is assigned to either LAN port (either
option), the unselected option is no longer
available. To clear a gateway address, select the
available option (4 or 14) and press the <Enter>
key with no gateway value entered.
5 and 15 broadcast:
Not required.
6 and 16 mtu:
Set the maximum
the number of bytes
(payload) in a frame.
• This value affects the performance of the system. A large
value can cause packets to be fragmented; a small value may
not make efficient use of the network capacity.
• The default value is 1500. In certain cases, you may need to
change this value to better match the network.

7 controller ip:
Set the IP address of
the system controller.
• Enter the IP address of the LAN port (option 2 or 12) over
which control data is sent to the VNC 325 that is designated
as the controller into all codecs in the system.
NOTES: • For proper operation, option 7 in all codecs
must have the same IP address.
• Once you have designated a codec as the
controller using option 7, you can access it via
either of its LAN ports.
• Manually enter the IP address for the controller; use
no leading zeroes. For example: 192.168.0.1 is valid,
192.168.000.001 is not valid.
17 ip forwarding:
Not implemented. Do not change this value.

have the same port number.
18 webserver port:

settings.
Activate any changes made by rebooting the codec.
Changes are not activated until the codec is rebooted.
NOTE: Entering reboot at the terminal emulation program
cursor also resets the unit.
