Modify Soft Switch Settings
Refer to the table below for the default Soft Switch settings and Soft Switch modification
information.
Table C-1. Soft Switch Settings
Parameter Description
Station Address The station address parameter is the Medium Access Control (MAC) address of the
station being configured. The MAC address is a 12-digit hexadecimal number
which is organized as 6 bytes, each represented by a pair of hexadecimal digits.
Default Setting - The default value is <<000000000000>> . This value instructs the
Ethernet Interface to use the factory-set, globally-unique MAC address in its EEPROM.
Modification fr om Default Setting - If changed, the Ethernet Interface will store the
new Station Address in the EEPROM and use it instead of the factory default.
Load Source The load source field defines the load source for the GEnet LAN software.
Default Setting - The default setting for this field is “A LT ”. This means that the
Ethernet Interface module will try to obtain a load from the serial port and the
network (in that order). The software will alternate between the two load sources
until one is found.
Modification from Default Setting - You may wish to specify the load source. The load
source may be changed to:
“LOC” (serial port) - only
“NET” (network) - only
If the load source specified is not available for the module, it will wait indefinitely for
that load source to be made available.
LAN Online This parameter tells the GEnet LAN Interface module whether to connect to the LAN
after initialization.
Default Setting - The default setting is YES. This means that the module will
connect to the LAN.
Modification from Default Setting - The default may be changed to NO. This
means that the module will not connect to the LAN.
Backplane On-
line
This parameter tells the GEnet LAN Interface module whether or not to allow back-
plane communications.
Default Setting - The default setting is YES. This means that the module will allow
all forms of backplane communications.
Modification fr om Default Setting - The default may be changed to NO. This
means that the module will only allow diagnostics mail traffic. This setting will not
permit application data transfer with the Series 90-70 CPU.
Network Load
Address
The multicast address to be used by the LAN Interface to load across the LAN. It is in
the same format as the Station Address.
Default Setting - The default value is <<000000000000>> . This value instructs the
LAN Interface to use the default network load address, <<090060000000>> , as its
load address.
Modification from Default Setting - If changed the Ethernet Interface will look for a
network load from the specified multicast address. This MUST be a multicast address.
