To configure Host to LAN 1 to BOX 1
To configure the Host to LAN 1 to BOX 1 communication, the following configuration file need to
be created.
• X.25 generic configuration file, x25_lan_1_box_1
• LLC2 configuration file, llc2_2_lan_0_lan_1
The x25_lan_1_box_1 file is created in the /etc/x25 directory. It will contain all the level 2 and
level 3 parameters. It will also contain the following entries:
device lan1
XOL_logical_port_id 1
XOL_destination_macaddr 0x080009C4728A
XOL_DSAP 0x7E
XOL_SSAP 0x7E
There is only one LLC2 specific configuration file per Host. The file is llc2_lan_0_lan_1.
To Start and Stop above configuration:
Starting:
After reconfiguring the kernel of the two boxes execute the following commands at the command
prompt:
x25init -c x25_lan_0_box_0 -L llc2_lan_0_lan_1
x25init -c x25_lan_1_box_1 -L llc2_lan_0_lan_1
Stopping:
To stop the configuration, execute the following commands at the command prompt:
xstop -d lan0 -L 1 # stop XOL interface with logical port id 1 on lan0
xstop -d lan1 -L 1 # stop XOL interface with logical port id 1 on lan1
To connect Box 0 to Host
To implement the above configuration, the following configuration files need to be created on the
BOX 0.
• Generic X.25 configuration file, x25_box_0_host.
• LLC2 configuration file, llc2_lan_2

configuration file, /etc/x25/x25init_llc2_smpl.
The file x25_box_0_host must contain all the mandatory level 2 and level 3 parameters. Along

device lan2
XOL_logical_port_id 0
XOL_destination_macaddr 0x080009DBEA7
XOL_DSAP 0x7
XOL_SSAP 0x70
The LLC2 specific configuration file, llc2_lan_2 is created in the /etc/x25 directory with the
following entries:
