ICX disconnected from Unleashed; connectivity issues between AP and ICX

[jacob_hutcheson]

Like everyone else here I have a Lennar-provided ICX 7150 and two APs. Something happened over the weekend and the ICX started showing up as Disconnected in the Unleashed GUI. Symptomatically things were 'connected', but traffic through the ICX to our ISP's stupid combo modem/router was having lots of issues.

I searched around on these forums (before finding the Lennar-specific section) and found some people with similar problems getting an ICX to connect to Unleashed. I tried factory resetting the ICX and re-adding it, but that didn't work. The ICX shows up in Unleashed as Pending, then prompts to enter the IP to join it (Auto Approve is enabled but seems like the ICX is in 'Router' mode per the docs?).

No matter what I have tried, after approving the ICX, it tries connecting and then shows up as Disconnected with a message that the ICX could not be pinged. 

I also updated the ICX to 08.0.90f via TFTP, but the result was the same.

I verified that LLDP is fine between the ICX and APs, but ICMP is not. I indeed can't ping the ICX from the AP, but I can ping it when I'm on the wired network from the ISP router. Interestingly when I'm connected to the router, I can't ping the AP directly. I can ping the AP if I'm on the wifi network being broadcast by Unleashed, but then I can't ping the ICX.

I know that was pretty hand-wavy but I can clarify if needed.

My situation is a little weird. During this weekend, there was a blackout and like most people here I have a Lennar provided ICX-7150. When the power finally came back on the internet was super slow. I then did all the hard reboot and it was still slow, then I unplugged the ethernet cable that was connected to the switch to the ISP router and switched it to another port on the switch then it started running super fast. A day past, and it's slow again, and I keep having to switch ports everyday. I then read this thread as well as others and people seem to have similar issues. But yeah, probably give support a call tomorrow. Thanks for your input!

Hi All,

Solution is simple, if root cause is same as discussed in this thread.

1. Check if your switch is running in router image (show ver).
2. If yes, make sure you boot the switch with switch image and make it permanent (make boot preference in configure mode), save the settings.
3. For more stable fix, make sure primary and secondary both boot images has switch code, not router.
4. Above steps needs to be performed on ICX CLI, not on Access point CLI.

I can't enter the ICX CLI through Putty without the ip address (not assigned to ICX see below image). I know this is probably a very simple task, but how do I assign an ip address to ICX CLI without entering the CLI? 

[syamantakomer]

Error shows ICX is not yet joined controller.

You have to use console access and login into the ICX first and then assign the IP address.

Once that is done, approve the AP on Unleashed and you can manage it from Unleashed.

SUCCESS! Thank you so much!

Edit: I would still like to know where to find the commands to 'boot into switch mode' are... for posterity.
