The
Channel mode
field reflects the current channel mode of the CEA-852 device. It is
configured by the configuration server. If there are any two devices in the channel which
use the same IP address but different ports (e.g., multiple devices behind one NAT router)
the channel switches to
Extended NAT mode
. Please refer to Section 7.3 to learn more
about configuring the Extended NAT mode in the configuration server.
The configuration server sets the
SNTP server
addresses and the
Channel timeout
.
The filed
Escrow timeout
defines how long the CEA-852 device on the L-IP waits for out-
of-sequence CEA-852 data packets before they are discarded. Please enter the time in ms or
‘0’ to disable escrowing. The maximum time is 255 ms.
The field
Aggregation timeout
defines the time interval in which multiple CEA-709
packets are combined into a single CEA-852 data packet. Please enter the time in ms or ‘0’
to disable aggregation. The maximum time is 255 ms. Note that disabling aggregation will
negatively affect the performance of the CEA-852 device of the L-IP.
The field
MD5 authentication
enables or disables MD5 authentication. In the following
field
MD5 secret
enter the 16-byte MD5 secret. Note that for security purposes the active
MD5 secret is not displayed. You may enter the 16 bytes as one string or with spaces
between each byte, e.g., 00 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF.
Note:
MD5 authentication cannot be used together with the Echelon’s i.
LON
1000 since the
i.
LON
1000 is not fully compliant with the CEA-852 authentication method. MD5 can be
used with the i.
LON
600.
Also note that entering the MD5 secret on the Web interface may pose a security risk. Since
the information is transmitted over the network it can be subject for eavesdroppers on the
line. It is recommended to use a cross-over cable.
In the field
Location string
the user can enter a descriptive test which identifies the
physical location of the device. A location string can have a maximum length of 255
characters. This is optional and for informational purposes only.
If the CEA-852 device on the L-IP is used behind a NAT router, the public IP address of the
NAT router or firewall must be known. To automatically detect the NAT address leave the
Auto-NAT
checkmark enabled.
The
Multicast Address
field allows the user to add the CEA-852 device of the L-IP into a
multi-cast group for the CEA-852 IP channel. Enter the channel’s IP multi-cast address
here. Please contact your system administrator on how to obtain a valid multi-cast address.
To learn when it is beneficial to use multi-cast addresses in your channel please refer to
Section 7.4.
6.2.11 CEA-709 Router Configuration
The CEA-709 router configuration page allows configuring the built-in router mode.
Available modes are
Configured Router
and
Smart Switch
. The device must be rebooted
to let the changes on this page take effect.
Choose Configured Router mode if you want to use the L-IP as a standard configured
CEA-709 router that can be commissioned and configured in a network management tool
such as NL-200 or LonMaker.
The Smart Switch mode lets the device act as a self-learning router like the L-Switch. In this
configuration the device’s router doesn’t need to be configured with a network management
tool but is completely transparent in the network. Use this operating mode in a plug&play
networking environment. The switch mode should only be used in LAN networks. In Smart
