Configuring Network Usage
To configure preferences that affect how your system functions with other servers and devices on your local network, access 
Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Ge\be\fal.
NOTE
This unit cannot detect a change to its IP address if the change i\Bs due to a change in networks from a wiring closet or through 
software, such as a change\B to a router configuration. Reboot the system if the DNS chang\Bes.
Specifying a Locally Configured IP \fddress 
Dynamic Host Configuration Protocol (DHCP) is used\B to dynamically allo\Bcate and assign IP addresses. DHCP allows you to 
move network devices from one subnet to another without adm\Binistrative attention.  You can choose to enable DHCP if a \B
DHCP server is present. If you disable DHCP, you must enter an IP address (the locally co\Bnfigured IP address if not assigned by 
a DHCP server), subnet mask (u\Bsed to partition the IP address into a network and host identifier\B), and gateway (IP address of 
the default gateway the system uses).
Specifying the Hostname and Domain N\Tame Service (DNS) Servers
You can enter the hostname of th\Be system and the IP addresses to configure DNS servers. You can also enter the domain 
names to search when resolving hostnames. Domain Name System (DNS) translates names of network nodes into addresses; 
specify this preference to use DNS to resolve the hostnames of d\Bevices to IP addresses.
Specifying Network Speed
If you choose an option\B other than \futo for the Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Ge\be\fal : Netwo\fk Speed 
preference, ensure that it matches the speed and \Bduplex configured on your network switch.
NOTE
 If your Ethernet switch is configured for half duplex, you may experience poor quality video when placi\Bng calls greater 
than 512 Kb/s. 
To work around this issue, change your Ethernet switch configuration to a setting other tha\Bn half duplex when\B using \futo 
for the Network Speed preference.

Specifying a VL\fN Tag
If you have static virtual local area networks ( VL\fNs) configured in your environment, you can configure your system to apply 
a VL\fN tag to outgoing packets and only accept \Bincoming tagged pac\Bkets that have the same VL\fN identifier. 
To enable this feature, navigate to Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Ge\be\fal : VLAN Tag and specify the VL\fN 
identifier of the VL\fN to which the system is assigned. The value is a numb\Ber in the range 1 th\Brough 4094.
NOTE
If you set or modify the\B VL\fN Tag preference, the system reboots when you navigate to another screen.
Specifying an NTP Server
The system date and time that appea\Br in the user interface are automatically set if on\Be of the following conditions exi\Bsts:
• The Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Ge\be\fal : DHCP preference is set to Enabled, and the DHCP server can pass 
an NTP server address to your system.
- or -
• The hostname or IP ad\Bdress of an NTP server is specified in \BAdmi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Ge\be\fal : NTP 
Se\fve\f Host\bame.
NOTE
\fn NTP server address that a DHCP server passes to your system overrides an NTP server hostname or address specified 
in the NTP Server Hostname preference.
The System Information page displays the IP address of the NTP server that the system uses.
NOTE
The time zone is not set automatically. If you did not specify \Bthe time zone for your system during the initial confi\Bguration, 
the time that appears in the user interface may not be correct. To specify the time zone manually, refer to “Manually Setting 
System Date and Time” on page 47.
Enabling IPv6 \fddressing
This system supports dual configuration\B of IPv4 and IPv6 a\Bddressing for the system IP address only. You cannot disable I\BPv4 
addressing on your system. Calls placed with an\B IPv6 address use the H.323 p\Brotocol.
In addition to specifying a loc\Bal IPv4 IP address (through either DHCP or \Bby manually specify\Bing a static IP addr\Bess), you can 
assign an IPv6 address to your system if you are using IPv6 addressing on your network. \fccess Admi\bist\fato\f P\fefe\fe\bces : 
Netwo\fk : Ge\be\fal and choose Enable\Bd for the IPv6 preference.
If your IPv6 network sends router advertisements, select \futo for the IPv6 Configuration preference to automatically assign 
the IPv6 address to the system. The default option is\B \futo. If you select Manual for this preference, you can specify a s\Btatic 
IPv6 address for the system in the IPv6 \fddress preference and the address of your IPv6 router in the IPv6 Router preference.
NOTE
Enabling or disabl\Bing IPv6 causes the \Bsystem to reboot after you exit the preference screen.
The IP address that appears at t\Bhe top of the main screen in the user interface is the IPv4 add\Bress. The IPv6 address of the 
system appears in the S\Bystem Menu on the System Information page. 
\fll other configurati\Bon preferences that require an IP address (for example, the NTP and DNS se\Brvers, H.323 gatekeeper, 
and SIP server) must be IPv4 add\Bresses. You must also use the\B IPv4 address for your system to access the system remotely 
through the web administration in\Bterface and an ssh se\Bssion. 
The directory supports IPv6 addresses. Users can also m\Banually dial IPv6 a\Bddresses using the Video Call or Voice Call buttons 
on the main screen of the user interface and the 0x1a text entry method or screen keyboard. Refer to “Manually Dialing a \B
Number from the Main Screen” on page 57 for information about changing the text entry mode.

Enabling Network \fddress Translation (N\fT)
Network \fddress Translation (N\fT ) enables communic\Bation between devices on your L\fN that have private IP addresses and 
devices that are accessed through a public IP ne\Btwork. Static N\fT ensures that the same publ\Bic IP address always maps to a 
system’s private IP address so that data from the public network intended for the private system can be routed to the system 
reliably. 
If you are using static N\fT to associate a public IP address with the private IP address of your system, you must configure your 
system to work with your static N\fT server. \fccess Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : NAT and select Enabled for the 
Static N\fT preference. 
Enter the public IP add\Bress, hostname, or fully qualifie\Bd domain name of y\Bour system in N\fT Public IP \fddress. The default 
entry method for this preference is numeric. To enter text, use the  key on the remote control to change the entry 
method to text.
NOTE
 If you are using a static firewall or N\fT with fixed ports, you cannot register to a public gatekeeper. If you configure H.323 
settings and enable \BH.460 support, the system ignores preferences in Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : NAT. 
Refer to “Enabling H.460 Su\Bpport for H.323 Calls” on page 43 for more information.
The following functions are not supported if your system is accessed from a web browser outside a firewall and static N\fT is 
enabled:
• System Upgrade
• Directory Import
To work around this issue, execute these functions from within the firewall.
Restricting Reserved Ports
By default, your system communicates through TCP and UDP ports in the range 2 04\B8 to 65 534 for video, voice, 
presentations, and camera control. The system uses only a sma\Bll number of these \Bports during a call. The exact number 
depends on the numb\Ber of participants in the call\B, the protocol used, and the number of\B ports required for the type (video 
or voice) of call.
To minimize the number of UDP \Band TCP ports that are available for communication, y\Bou can restrict the range by entering 
values in Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Rese\fved Po\fts. L\b recommends that the ra\Bnge you choose, if other than 
a subset of the defa\Bult range, begins with a port number greater than 10 000.
NOTE
Changing the TCP range causes an \Bautomatic reboot of the system.
\fn H.323 video call\B with a presentation requires more ports than other types of calls. 
The following tables identify\B the number of ports required per connection by protocol and the type (video or voice) of call. 
Use this information if you need to further restrict the port range.

Configuring Quality of Service
You can specify network Quality of Service (QoS) settings in the Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : Netwo\fk QoS 
preferences. 
Set these preferences according to the settings used i\Bn your network.
NOTE
Network QoS preferences are supported with IPv4 addressing only. If you enable IPv6 addr\Bessing on your LifeSize system, 
QoS preferences are ignored for IPv6 calls.  For more information about IPv6 ad\Bdressing, refer to “Enabling IPv6 \fddressing” 
on page 36.
You can specify Diff\BServ (differentiated services) or IntServ (integrated services) values for audio, video, and data packets. 
You can also set the \BIntServ Type of Service ( ToS) preference.
Configuring LifeSize Transit Preferences
If you are using LifeSize Transit with your system, refer to your LifeSize Transit documentation \Bfor information about how to 
configure preferences in Admi\bist\fato\f P\fefe\fe\bces : Netwo\fk : LifeSize T\fa\bsit.

Disabling \fccess to the Local Directory
By default, users ca\Bn place calls usin\Bg entries in the local di\Brectory and add, remove, or modify these e\Bntries. 
For more information, refer to “Placing a Call from the Directory” on page 57.
\fdministrators can disable us\Ber access to the local directory by setting Local Directory to Disabled in Admi\bist\fato\f 
P\fefe\fe\bces : Di\fecto\fy : Ge\be\fal. 
Disabling access to the local directory also disables the\B following:
• saving entries from the REDI\fL list to the local directory
• copying corporate directory entries to the local directory
\fdministrators maintain access\B to the local directory on the web administration in\Bterface Directory page when the Local 
Directory preference is set to Disabled. For more information about managing the local directory from the web administration 
interface, refer to “Using \fdvanced Directory Features” on page 52.
Populating the Corporate Directory
Users can place ca\Blls from the directory by selecting a number to dial from a list of stored numbers. 
The corporate directory is H.350 complia\Bnt and can store up to 1000 entries in both an alph\Babetical and hierar\Bchical format. 
\fll users can manag\Be entries in the local di\Brectory. Only administrators can manage entr\Bies in the corporate directory.
You can populate the corporate directory by configuring \futo Discovery preferences or Lightweight Directory \fccess 
Protocol (LD\fP) preferences in Admi\bist\fato\f P\fefe\fe\bces :Di\fecto\fy. By default, auto discovery is enabled and L\BD\fP 
is disabled. You can enable only\B one of these method\Bs. The system automatically disables\B the other method to prevent 
duplicate entries from appearing in the corporate directory. The status of these me\Bthods, either enabled or\B disabled, appears 
on the Admi\bist\fato\f P\fefe\fe\bces : Di\fecto\fy screen. The connection status of the LD\B\fP installation also \Bappears on this 
page and on the System Information page. 
The values that can a\Bppear for the connection status include t\Bhe following:

Reading from an LD\fP Server
When you enable and confi\Bgure LD\fP preferences to populate the corporate directory, you specify the hostn\Bame, login and 
query parameters, and the refresh interval for reading data from a preconfigured LD\fP server. L\b recommends that you use 
an LD\fP server configured with an H.350 co\Bmpliant schema.
LDAP Conne\ftion Status Des\fription 
Unregistered LD\fP preferences are not configured.
Registered LD\fP preferences are configured. The last attempt by the system to contact the LD\fP 
server and receive data was successf\Bul.
Unreachable LD\fP preferences are configured, but the LD\fP hostname is invalid or the service does 
not exist.
Unauthorized LD\fP preferences are configured, but the username or password is invalid.
Invalid Syntax LD\fP preferences are configured, but the base Distin\Bguished Name (DN) \Bis invalid.
Failed LD\fP preferences are configured, but an unexpected failure occurred.
Configuring \futo Discovery
\futo discovery enables the systems on your network to pass address information to other systems automatically. 
By default, when a s\Bystem joins a network, it sends a broadcast packet to the local subnet to announce its presence. 
\fny system on the local sub\Bnet that receives the packet and has \futo Discovery set to Enabled replies by sending address 
information about itself a\Bnd a list of IP addr\Besses of other systems that it has disco\Bvered.
The system creates an entry in its corporate directory for every system on the local sub\Bnet from which it received a response. 
It then queries the list of other\B IP addresses that it received and the IP addresses that are stored in its own Redial list, but 
only if those addresses are allowed by the filters that you specify in the \futo Discovery Subnets and \futo Discovery Ignored 
Subnets preferences. 
By default, the system replies and sends q\Bueries to other systems in the local su\Bbnet only.
Configure the \futo Discovery Subnets and \futo Discovery Ignored Subnets preferences to enable the system to discover 
other systems outside the loca\Bl subnet and share that information with other sys\Btems. 
Specify subnet filters (separated by spaces) in the \futo Discovery Subnets preference to identify the subne\Bts to which the 
LifeSize system can send queries and replies. 
By default, the preference is empty; the system sends queries and replies to other systems on the local su\Bbnet only.
To exclude subnets from auto discovery, specify subnet fil\Bters in the \futo Discovery Ignored Subnets preference. If a 
destination address does not match one of the filters in the \futo Discovery Subnets preference, or if it matches one of the 
filters in the \futo Discovery Ignored Subnets preference, then the system does not query or reply to the system at that 
address.
For example, you can configure the \futo Discovery Subnets preference to include a large subnet and the \futo Discovery 
Ignored Subnets preference to exclude a subset of th\Be subnet. Consider a network that has several subnets with the\B IP 
address 10.* and a slo\Bw network connection to devices that have a 10.85.* address. If you enter 10.* in the \futo Discovery 
Subnets and 10.85.*\B in the \futo Discovery Ignored Subnets preference, the system queries and replies to all the systems that 
have a 10.* address, except those that have a 10.85.* address. 
If you set \futo Discovery to Disabled, the system does not send a \Bbroadcast message to the local subnet a\Bnd cannot 
discover or be discovered by other systems.
