Dominion KX II – Frequently Asked Questions
© 2012 Raritan Inc. Page 8 of 18 V1098 R6 May 2012
I’m having problems
connecting to the Dominion
KX II over my IP network.
What could be the problem?
The Dominion KX II relies on your LAN/WAN network. Some possible problems
include:
• Ethernet auto-negotiation. On some networks, 10/100 auto-
negotiation does not work properly, and the Dominion KX II unit must
be set to 100 Mb/full duplex or the appropriate choice for its network.
• Duplicate IP address. If the IP address of the Dominion KX II
is the same as another device, network connectivity may be
inconsistent.
• Port 5000 conflicts. If another device is using port 5000, the Dominion
KX II default port must be changed (or the other device must be
changed).
• When changing the IP address of a Dominion KX II, or swapping in a
new Dominion KX II, sufficient time must be allowed for its IP and Mac
®
addresses to be known throughout the Layer 2 and Layer 3 networks.
IPv6 Networking
What is IPv6?
IPv6 is the acronym for Internet Protocol Version 6. IPv6 is the “next generation”
IP protocol which will replace the current IP Version 4 (IPv4) protocol.
IPv6 addresses a number of problems in IPv4, such as the limited number of
IPv4 addresses. It also improves IPv4 in areas such as routing and network
auto-configuration. IPv6 is expected to gradually replace IPv4, with the two
coexisting for a number of years.
IPv6 treats one of the largest headaches of an IP network from the
administrator’s point of view – configuring and maintaining an IP network.
Why does Dominion KX II
support IPv6 networking?
U.S. government agencies and the Department of Defense are now mandated
to purchase IPv6-compatible products. In addition, many enterprises and foreign
countries, such as China, will be transitioning to IPv6 over the next several
years.
What is “dual stack” and
why is it required?
Dual stack is the ability to simultaneously support both IPv4 and IPv6 protocols.
Given the gradual transition from IPv4 to IPv6, dual stack is a fundamental
requirement for IPv6 support.
How do I enable IPv6 on the
Dominion KX II?
Use the “Network Settings” page, available from the “Device Settings” tab.
Enable IPv6 addressing and choose manual or auto-configuration. Consult the
user guide for more information.
What if I have an external
server with an IPv6 address
that I want to use with my
Dominion KX II?
The Dominion KX II can access external servers via their IPv6 addresses, for
example, an SNMP manager, syslog server or LDAP server.
Using the Dominion KX II’s dual-stack architecture, these external servers can
be accessed via: (1) an IPv4 address, (2) IPv6 address or (3) hostname. So, the
Dominion KX II supports the mixed IPv4/IPv6 environment many customers will
have.
Does the Dominion KX I
(the previous generation
KX) support IPv6?
No. The Dominion KX I does not support IPv6 addresses.
What if my network doesn’t
support IPv6?
The Dominion KX II’s default networking is set at the factory for IPv4 only. When
you are ready to use IPv6, then follow the above instructions to enable
IPv4/IPv6 dual-stack operation.
Where can I get more
information on IPv6?
See www.ipv6.org for general information on IPv6. The Dominion KX II user
guide describes the Dominion KX II’s support for IPv6.
