• LAN Interface Speed & Duplex. Select from among the speed and duplex combinations
available.
Autodetect Default option
10 Mbps/Half
10 Mbps/Full
100 Mbps/Half
100 Mbps/Full
1000 Mbps/Full Gigabit
− Half-duplex provides for communication in both directions, but only one direction at a
time (not simultaneously).
− Full-duplex allows communication in both directions simultaneously.
Note: Occasionally there are problems running at 10 Mbps in either half or full duplex. If
you are experiencing problems, please try another speed and duplex.
Please refer to Network Speed Settings for more information.
• Enable Automatic Failover. Check this checkbox to allow Dominion KX II to automatically
recover its network connection using a second network port if the active network port fails.
When this option is enabled, the following two fields are used:
− Ping Interval (seconds). Ping interval determines how often Dominion KX II checks the
status of the network connection (setting this too low may cause excess network traffic).
The default Ping Interval is 30 seconds.
− Timeout (seconds). Timeout determines how long a network port must be “dead” before
the switch is made. Both network ports must be connected to the network and this option
must be checked for Automatic Failover to function. The default Timeout is 60 seconds.
Note: The default Ping Interval and Timeout generate a condition that when the KX device
tries to switch over, remote sessions will be dropped and must be re-established. Reducing
these intervals to much lower values will allow remote sessions to stay connected, but will
result in increased network traffic.
• Set System ACL. Click this button to set a global-level Access Control List for your
Dominion KX II by ensuring that your device does not respond to packets being sent from
disallowed IP addresses. The IP Access Control
page opens.
Note: These ACL values are global, affecting the Dominion KX II unit as a whole. You can
also create ACLs on a group-level basis. For example, you can create an “Outsourced
Vendors” user group that is permitted to access Dominion KX II only from a given IP
address range (refer to Group-based IP ACL
for more information on how to create group-
specific Access Control Lists).
