Faucet on ZodiacFX

Introduction

ZodiacFX is a small 4 port multi table OF1.3 switch from Northbound Networks.

Caveats

• ZodiacFX allows only one controller (so you cannot run Gauge).
• The default OF port is 6633; it is recommended to use 6653.
• It is recommended to enable ether type filtering to minimize corrupt packets.

Applying recommended config

You can use the following expect script to program the recommended configuration:

conf-zodiac.sh

#!/usr/bin/expect

##
## configure ZodiacFX with recommended settings.
##

# Serial port assigned to ZodiacFX
set port /dev/ttyACM0

set timeout 5
set prompt {Zodiac_FX\#}
set configprompt {Zodiac_FX\(config\)\#}
set spawned [spawn -open [open $port w+]]

send_user "get initial prompt\n"
send "\r"
send "\r"
expect -re $prompt
send_user "found initial prompt\n"
send "config\r"
expect -re $configprompt
send_user "setting ethertype-filter\n"
send "set ethertype-filter enable\r"
expect -re $configprompt
send_user "setting of-port"
send "set of-port 6653\r"
expect -re $configprompt
send "save\r"
expect -re $configprompt
send "exit\r"
expect -re $prompt
send "restart\r"
expect -re "Restarting"

Example of running the script:

$ sudo ./conf-zodiac.sh
spawn [open ...]
get initial prompt
