The third partition "/dev/sda3" is mounted in the file system.
Procedure
To use the Management tool, proceed as follows:
1. Change your working directory.
pt1@debian:~# cd /opt/SIEMENS/SWCPU/bin
2. To start the Management tool, execute the command "./s7_vnic_macconfig".

If you specify the parameter "
-h" or no parameter after the "./s7_vnic_macconfig"
command, a list with the permitted parameters and a description opens.
3. Read out the MAC addresses with the parameter "-m" and the directory. The parameter
"m" must always be specified.
pt1@debian:/opt/SIEMENS/SWCPU/bin# ./s7_vnic_macconfig -m /opt/SIEMENS
