illegal class reported by PD

daniel_cumming — Wed, 18 Nov 2020 15:31:08 GMT

I have a Ruckus ICX 7450-48P that is having issues with a few new wireless access points. Under inline power I am getting a fault error "illegal class reported by PD" for 4 of these ports with these access points. There are 2 other of these same exact APs plugged into 2 different ports that work fine. I've doubled checked the config on these ports and compared it to the working ports. Everything appears identical. I'm not sure what is causing this issue.

What is the model of AP? Please also gather:

show inline power

show inline power details

show inline power emesg

@benbeck The APs are Ubiquiti UAP-AC-HD. We've installed over 100 of them in our district over the last week, connected on Ruckus switches, and none of them have had this issue. Only on this one switch.

I'm having trouble posting the output from the requested show commands.

It's hard to say without being able to see any output. I would recommend opening a support case and gathering a 'show tech' and the data I requested above. That should be a good start in order for one of our engineers to take a look.

I opened a support case yesterday and sent him the logs. I'm waiting to hear back. I posted here to see if anyone else had any ideas.

Got it. I would maybe give this a shot and see if anything changes:

conf t

lldp run (ensuring LLDP is on)

interface eth x/y/z

inline power power-by-class 4 (this should be up to 30watts)

interface eth x/y/z

inline power power-limit 30000

Let me know if that changes anything. Also, do your APs use LLDP for power negotiation?

I tried those commands but they didn't make a difference. I'm not sure if the Ubiquiti APs use LLDP for power negotiation.
