Ifconfig down
Stops Receive and Transmit State Machines of the MAC (Media Access
Controller)
Clears up the descriptor list
Resets PHY (Physical Layer) and MAC
Starts Autonegotiation
Ifconfig up
Executes startup procedure and initializes MAC and PHY
Configures the descriptor list
Waits for and interprets the Autonegotiation results
Sets network operation mode
ifconfig down and ifconfig up are useful to clear up dubious states of the network
interface. Type on

The logical names of the network subsystems on CU09/10 are:
fe0 Fast Ethernet, 10/100 BaseT
la0 Thin Wire Ethernet, 10 Base2 (if available)
3. 5. 2. Switching the boot interface
CU09/10 can boot over Fast Ethernet or Thin Wire Ethernet 10Base2 (if available). The
controller to be used can be determined by its logical name between the brackets of the
bfs–call included in the CU09/10 boot command:
boot –f bfs(0,la)/usr/diskless/clients/spect/root/unix
This call leads to booting over 10Base2. The CU09/10 monitor will boot over Fast Ether-
net if
fe is inserted instead of la or as default if no name is set:
boot –f bfs()/usr/diskless/clients/spect/root/unix
If the boot procedure is called by the monitor commands u or auto the parameter of the
bootfile in NVRAM will be used.
This parameter can be set in the monitor like this:
setenv bootfile bfs(0,la)/usr/diskless/clients/spect/root/unix
The boot procedure can be interrupted by typing Ctrl C.
3. 6. Ethernet addresses
The Ethernet address consists of 12 hexadecimal digits. The 6 leftmost ones are the
constant Bruker Code, the 2 rightmost ones identify a special group of Bruker devices.
The rest of them build the consecutively numbered ethernet address of each device.
To the 2 Ethernet subsystems of CU09/10 will be assigned addresses out of group 09
(Fast Ethernet) and out of group 06 (10Base2).
10Base2 Ethernet (la)
