Unleashed will not connect to ICX switch

louis — Thu, 01 May 2025 00:45:01 GMT

I know the forum is full of posts about problems with the Unleashed ICX switch management feature, I apologize for creating yet another one. I wasn't able to find an existing one that quite fit the problem I'm having, though there are so many, maybe I missed one...

Unleashed 200.17.7.0.152 will not connect to an ICX7550-48ZP firmware 08.0.95m. This switch was working fine with Unleashed for a few years, until I replaced the master AP R850 with an R770. Since then, Unleashed will not connect to the switch. Logs indicate the issue is an authentication failure, incorrect password, but I am able to ssh into the switch using the Unleashed credentials for password authentication just fine. I haven't seen any other problems with the network or Unleashed since replacing the AP.

Things I've tried...

Manually remove and re-add the switch in Unleashed. No effect.
Wait for Unleashed to discover the switch via LLDP and manually "Approve". No effect.
Enable automatic switch approval, wait for unleashed to discover it. No effect.
On the switch, manually configure the default user state that Unleashed so desperately hopes for. Create username `super` password `unleashed`, and delete all other switch users. Unleashed successfully logs in as `super`, and it creates a user matching the Unleashed `admin` user. I'm able to ssh into the switch as the `admin` user that Unleashed created using the expected password. But Unleashed itself cannot authenticate with the `admin` user it created. Same error as shown in logs above.

The nuclear option of factory resetting the switch is not something I want to do, nor should I need to do.

Problem solved!

Apparently the Unleashed ICX switch management feature is picky about passwords. Unleashed itself might be ok with a given password, but the Unleashed ICX switch manager may fail if you've chosen a password it doesn't like. I was not able to determine the exact limitation the Unleashed ICX switch manager has with passwords, see passwords tested that work and don't work below. I have no idea why swapping a master R850 with an R770 would have revealed this problem. The Unleashed firmware version did not changed, only the AP model, and the password I had been using for Unleashed to manage the ICX switch had not changed in a couple of years.
