ASX200BX Config and info

Password Recovery

Old ASX-200 (not BX model)

Default is user “asx” and password “f0replay”

Fore ASX200

Nothing done with this as I managed to get a BX model. This is a switch based on a SUN SPARC board running an early solaris, although it is inaccessible to the user.

New ASX-200BX

This is the baby brother of the larger chassis based asx1000 ASX1000 ASX200BX

Password Reset sex

With a terminal attached to the serial port, reset the switch using a straightened paper clip.

When “Decomp…” displays on the front panel display, press and hold the “Next” and “Select” buttons.

After a short time the display should stop scrolling. When you release the buttons, the prompt “Boot without reading flash? (y/n)” should be displayed on the terminal. Type “y” and press <Enter>.

The promt “Clear the AMI password?” (y/n) will be displayed. Type “y” and press <Enter>.

The AMI user account on the switch now has no password.

The ami username didn't work for me, but here's what did.

Press Enter repeatedly when the unit boots, or press Ctrl-Break after the unit boots to get to the Mon960 prompt (⇒).

Normally this prompt is used to upgrade the switch, but it can also be used to clear the configuration.

then reboot the switch.

The switch will come up in factory testing mode, choose option 10 to turn this mode off and reboot. You should have a factory fresh configuration.

Set to

PVC setup

Configure a test circuit on our Fore ATM switch. for the purposes of this exercise we will use circuit 0/90. A cisco router is connected to port 1A1, and a linux machine is connected to port 1C4.

configuration vcc new 1A1 0 90 1C4 0 90
configuration vcc new 1C4 0 90 1A1 0 90

From Linux Journal.

Next, the switch must be configured to complete the PVC between the hosts. It is helpful to understand the port naming convention used by the Fore switch. The port names consist of three identifiers:

  • Board: the number of the switch board (same as the SCP number); each SCP controls one switch board.
  • Network Module: the slot (A, B, C, or D) in the switch board containing the port.
  • Port: the physical port number on the network module.

For example, port 1b3 refers to the first switch board, the second network module (module b) on board 1 and the third physical port on the second network module. The Fore ASX-200 switch has only one switch board, while the ASX-1000 switch has four. There is a maximum of four network modules per switch board and a maximum of six physical ports per module.

You must now create the virtual channels on the ATM switch. In our example, you would enter these commands on SCP 1:

localhost::> conf vcc
localhost::configuration vcc> new 1a1 0 70 1a2 0 70
localhost::configuration vcc> new 1a2 0 70 1a1 0 70

1a1 is the switch port for node1 and 1a2 is the switch port for node2.

The switch completes the PVC based on the input port to output port virtual channel connection (VCC) mapping. Note that the PVC vpi.vci (0.70) matches the vpi.vci given to the atmarp commands on the hosts.

The above commands will connect two ports on the same ATM switch board. The Fore ASX-1000 switch has up to four switch boards. If you are connecting machines on different switch boards, the procedure is more complicated, as you must connect each port to the switch fabric and connect the fabric to each port. Thus, if you wish to connect a machine on port 1a1 to a machine on port 3a1, the following commands are required:

On SCP 1:

localhost::> conf vcc
localhost::configuration vcc> new 1a1 0 70 1e3 0 70
localhost::configuration vcc> new 1e3 0 70 1a1 0 70

On SCP 3:

localhost::> conf vcc
localhost::>configuration vcc> new 3a1 0 70 3e1 0 70
localhost::>configuration vcc> new 3e1 0 70 3a1 0 70

On the Fore switch, the fabric connections are slot e. Therefore, port 1e3 refers to a connection from switch board 1 to switch board 3. Likewise, 3e1 refers to a connection from switch board 3 to switch board 1. Fore refers to these ports as “intra-fabric” ports.
