Zodiac FX General / Re: Zodiak FX sends wrong packets
« on: August 12, 2019, 12:47:13 PM »
ryu-manager 4.32

Small update: On my quest for happiness, I tried to use python 2 to see
if that would make a difference. It did not: Ryu continues to get disconnected
while talking to ZodiacFX on both OF1.0 and OF1.3.

On a happier note, I tried POX [1] and that worked fine! I do see the controller
connected continuously when POX is used instead of Ryu. Using the same VM and ZodiacFX.

Interesting, as I too am having issues with the controller connection when using Zodiac and Ryu's
simple_switch{_13,}.py Actually, I'm not convinced this is an issue with Zodiac at this point.
According to Wireshark, the packet_out message sent from Ryu is malformed on OF13. I tried the
same experiment with OF10 and do not see complaints from Wireshark, but the behavior is very
similar.

To reproduce this, I simply started a ping between a RPI and the VM where Ryu is running. Ports 1 and 2
of Zodiac FX is in between.

Then, I started ryu-manager:
   ryu-manager --verbose ./.env/lib/python3.6/site-packages/ryu/app/simple_switch.py
     -OR-
   ryu-manager --verbose ./.env/lib/python3.6/site-packages/ryu/app/simple_switch_13.py

Then, I captured packets in vm using command:
      IFACE=enpXXX ; sudo tcpdump -e -v -n -i $IFACE -w cap.cap

Since I'm using "Failstate: Safe" the flows do get installed from from this point on, ryu-manager script sees no
new messages but stays 'connected'. Which is a pain. Zodiac considers open-flow disconnected and makes
no attempt in reconnecting until I manually stop ryu-manager.

Hope this helps! Thanks.

Zodiac FX General / Re: Firmware Update: v0.80

Hi flaviof,

As you are upgrading from version 0.56 you need to follow the steps in section 2.3 of the User Manual

There is also a video on our Youtube channel that shows how to do a firmware upgrade - Zodiac FX - Upgrading the Firmware

Regards,
Paul

Perfect! Thank you very much for the link. I will get a PC and install SAM-BA utility.

Zodiac FX General / Re: Firmware Update: v0.80
« on: May 07, 2017, 08:01:17 AM »
Hello,

I am very new to northbound networks and am trying to update a
Zodiac FX-Rev A to v0.80.

I am trying to follow the update steps in the doc, but cannot see the 'update'
command available in the session I'm using [1]. So xmodem never starts.
I also cannot see the web interface on default ip address, but can ping
10.0.1.99 on port 4 ok.

Is that because my existing firmware is so old that none of these two hooks
were implemented? Please advice on how I can get v0.80 installed from 0.56

Thanks,
