Specifying a VLAN Tag
If you have static virtual local area networks (VLANs) configured in your environment, you can configure your system to apply a VLAN tag to outgoing packets and only accept incoming tagged packets that have the same VLAN identifier.
To enable this feature, navigate to Administrator Preferences : Network : General : VLAN Tag and specify the VLAN identifier of the VLAN to which the system is assigned. The value is a number in the range 1 through 4094.
NOTE
If you set or modify the VLAN Tag preference, the system reboots when you navigate to another screen.
Specifying an NTP Server
The system date and time that appear in the user interface are automatically set if one of the following conditions exists:
•The Administrator Preferences : Network : General : DHCP preference is set to Enabled, and the DHCP server can pass an NTP server address to your system.
- or -
•The hostname or IP address of an NTP server is specified in Administrator Preferences : Network : General : NTP Server Hostname.
NOTE
An 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 the time zone for your system during the initial configuration, 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 Addressing
This system supports dual configuration of IPv4 and IPv6 addressing for the system IP address only. You cannot disable IPv4 addressing on your system. Calls placed with an IPv6 address use the H.323 protocol.
In addition to specifying a local IPv4 IP address (through either DHCP or by manually specifying a static IP address), you can assign an IPv6 address to your system if you are using IPv6 addressing on your network. Access Administrator Preferences : Network : General and choose Enabled for the IPv6 preference.
If your IPv6 network sends router advertisements, select Auto for the IPv6 Configuration preference to automatically assign the IPv6 address to the system. The default option is Auto. If you select Manual for this preference, you can specify a static IPv6 address for the system in the IPv6 Address preference and the address of your IPv6 router in the IPv6 Router preference.
NOTE
Enabling or disabling IPv6 causes the system to reboot after you exit the preference screen.
The IP address that appears at the top of the main screen in the user interface is the IPv4 address. The IPv6 address of the system appears in the System Menu on the System Information page.
All other configuration preferences that require an IP address (for example, the NTP and DNS servers, H.323 gatekeeper, and SIP server) must be IPv4 addresses. You must also use the IPv4 address for your system to access the system remotely through the web administration interface and an ssh session.
The directory supports IPv6 addresses. Users can also manually dial IPv6 addresses 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 Number from the Main Screen” on page 57 for information about changing the text entry mode.
