interdependent. They must both be set to Automatic or they
must both be set manually. Manual settings should be used only
in the rare case when the VBrick is attached to network
equipment that does not support auto negotiation. The VBrick's
capabilities may be limited when its Ethernet link is at 10 Mbps
and/or Half Duplex. If auto negotiation fails, the VBrick defaults
to 10Mbit, half duplex and attempts "parallel detection," an
alternative way to sense speed. Status parameters are available on
the network status screen to indicate the state of the link and the
current configuration of the Ethernet hardware. In auto mode,
they reflect the results of the negotiation and in manual mode
they follow the configuration options.

the Network Auto Negotiate feature to work effectively, the
Ethernet switch must also support auto negotiation. A manually

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.
