Brocade ICX 6610 Switch

[ashubs]

Hello,

I recently acquired some older Brocade ICX 6610 switches that support OpenFlow 1.3. It turns out that the Brocade firmware is missing some OpenFlow messages:

I created a very simple configuration for the switch. The switch connects to the controller but the configuration doesn't seem to work.

description: "Port 47"
native_vlan: workstations
acls_in: [allow-all]

acls:
allow-all:
- rule:
actions:
allow: True

I think the missing messages are causing the switch and the controller to log the following errors:

From the switch:

Is there anything I can do to make the switch and the controller work?

Hi @ashubs,

I have a memory of trying faucet against brocade's openflow implementation back in 2018, and at that time they didn't support enough of the openflow spec to enable faucet to program the switch.

Based on your error messages I believe this is still the case, the switch lacks support for the openflow message types faucet uses, the only way to rectify this is to get a new firmware for your switch with improved openflow support.
