IP Network Failover Settings (AnywhereUSB/14 only)

The IP Network Failover feature allows the AnywhereUSB/14 to recover from an Ethernet failure.

The failover conditions are configurable, and once the AnywhereUSB/14 determines that the

primary Ethernet link has failed, it will automatically route the Ethernet traffic to the secondary

Ethernet link.

Advanced Network Settings

The Advanced Network Settings are used to further define the network interface.

Settings include:

• Host Name is placed in the DHCP Option 12 field. This is an optional setting which is only used

when DHCP is enabled.

• Static Primary/Secondary DNS are the IP addresses of Domain Name Servers (DNS) used to

resolve computer host names to IP addresses. Static DNS servers are specified independently

of any network interface and its connection state. An IP address of 0.0.0.0 indicates no server

is specified.

• DNS Priority is a List of DNS servers in priority order used to resolve computer host names.

Each type of server is tried, starting with the first in the list. For each server type, the primary

server is tried first. If no response is received, then the secondary server is tried. If neither

server can be contacted, the next server type in the list is tried. A network interface may obtain

a DNS server from DHCP or other means when it is connected. If an interface does not obtain

a DNS server, it will be skipped and the next server in the priority list will be tried. To change

the priority order, select an item from the list and press the up or down arrow.

• Ethernet Interface permits the configuration of Ethernet speed and duplex settings.

• TCP Keep Alive Settings include an Idle Timeout which specifies the period of time that a TCP

connection has to be idle before a keep-alive is sent, a Probe Interval in seconds between each
