VBrick MPEG-2 Appliance Admin Guide 11
Domain Name Server
Network Time Synchronization
These fields are used to synchronize network time using the host name or IP address of a
known server to provide a synchronized time for all appliances in the network. To enable
Network Time Synchronization after these parameters are set, go to Configuration: System >
General on page 44 and check the box.
Configuration: Network > Routing
The MPEG-2 Appliance requires no routing configuration for the vast majority of network
uses. Use these settings only in those rare cases when your network requires advanced routing
features in the appliance.
Maximum Transmission
Unit Size
Range 1024–1500 (default = 1500). The MTU is used for all
network traffic from the VBrick and defines the largest network
packet size that will be transmitted. A higher MTU brings higher
bandwidth efficiency and VBrick recommends using the default.
However you may wish to reduce MTU size to meet the
requirements of some networks with VPN or other security
tunnels that cannot tolerate 1500-byte packets.
Primary Server IP
Address
This is the primary server used for DNS.
Secondary Server
IP Address
This is the secondary server used for DNS.
Default Domain
Extension
This is the domain name used for DNS. Note that you can use the
default (blank) values for these items.
Note To Network Administrators. DHCP Option 4 is used by the DHCP server to return
SNTP server addresses. This option must be enabled in the DHCP server for these
addresses to be returned to the VBrick. If the DHCP server configuration is
unknown, it is recommended that the address(es) be manually entered since the
DHCP server-supplied address will always override a manually-entered address.
Primary Server IP Address
or Host Name
Primary host name (VBrick Host Name or DNS Host Name)
or IP address of valid SNTP server providing time
synchronization. A blank field indicates the server address
will be acquired via the DHCP server only if the
Network
DHCP
field above is checked.
Secondary Server IP
Address or Host Name
Secondary host name (VBrick Host Name or DNS Host
Name) or IP address of valid SNTP server providing time
synchronization. A blank field indicates the server address
will be acquired via the DHCP server only if the
Network
DHCP
field above is checked.
