Network preferences

Configure network settings in Preferences > Network.

DHCP or a static IP address DHCP dynamically allocates and assigns IP addresses.

If you disable DHCP, enter the locally configured IP address, subnet mask (used to partition the IP addresses into a network and host identifier), and default gateway.

NOTE: From your video system, select  and enter the passcode (by default, 1234) to access network settings .

Network speed Lifesize recommends that you select Auto negotiate speed and duplex settings unless your network specifically requires a fixed speed or duplex setting. If you do not select Auto negotiate speed and duplex settings, ensure that the values match the speed and duplex configured on your network switch.

NOTE: If your Ethernet switch is configured for half duplex, you might experience poor quality video when placing calls greater than 512 kb/s. Change your Ethernet switch configuration to a setting other than half duplex when you select Auto negotiate speed and duplex settings.

VLAN tag If you have static VLANs configured, you can configure your Lifesize system to apply a VLAN tag to outgoing packets and accept incoming tagged packets only if they share the same VLAN identifier. Specify the VLAN identifier of the VLAN to which the system is assigned. The value range is 1 through 4094.
DNS servers and domain Enter the IP addresses to configure DNS servers. Enter the domain names to search when resolving hostnames. DNS translates names of network nodes into addresses; specify this preference to use DNS to resolve the hostnames to IP addresses.
Search domains Domains are searched in the order you list them, and the search stops when a valid name is found. To search a name hierarchy, use search domains of varying scope. For example:
  • building.campus.university.edu
  • campus.university.edu
  • university.edu
Reserved TCP and UDP  ports By default, Lifesize video systems communicate through TCP and UDP ports in the range 60000 - 64999. Lifesize recommends that you use the default range. However, you can restrict the range of UDP and TCP ports that are available for communication. Lifesize recommends that the range you choose, if other than a subset of the default range, begins with a port number greater than 49151.
QoS Set QoS preferences according to the settings used in your network.
MTU of video packets Video packets that exceed the MTU size for any router or segments along the network path might be fragmented or dropped, resulting in poor quality video at the receiving device. You can set the MTU of video packets that your Lifesize system sends. The default value is 1440 bytes. The valid range is 900 - 1500 bytes. Lifesize recommends that you do not change this value unless your network requires a different MTU.
Static NAT If you are using static NAT to associate a public IP address with the private IP address of your Lifesize Icon, select Static NAT and enter the NAT public IP address or hostname of your Lifesize Icon.
802.1x authentication By default, 802.1x authentication is disabled on Lifesize Icon room systems. To learn how to enable, go to 802.1x Authentication.
