RAP-335 ENET0 unusable?

After configuring a few dozen AP335 as remote APs I've now had 3 times that a RAP would no longer boot from its ENET0.

Powercycling a RAP (physically unplugging the cable) that is stuck like that does not help resolve the issue.

Interrupting the APboot and triggering DHCP several times does not work (or help) either.

apboot> dhcp
eth0: No link.
eth1 Waiting for PHY auto negotiation to complete......... TIMEOUT !
eth1: No link.
apboot> dhcp
eth0: No link.
eth1 Waiting for PHY auto negotiation to complete......... TIMEOUT !
eth1: No link.
apboot> dhcp
eth0: No link.
eth1 Waiting for PHY auto negotiation to complete......... TIMEOUT !
eth1: No link.

Also letting the entire boot run its course does not help.

The fix for now has always been to boot once from ENET1, this has always resolved the issue.

After having booted from ENET1, now also ENET0 works again.

Problem is, these APs are to be installed where we can not easily unplug/replug those APs. I'd also rather not simply use ENET1 as in future models/deployement ENET1 might not be usuable to draw POE power from. Ans besides from that, I a not confident this issue is limited to ENET0 only.

 

Anybody got an idea what is going wrong here?  What could trigger an AP to pull down an interface across powercycles?

hi Koen

are always bad (and are a bug) - what s/w version are you on and whats the rap topology (split tun, bridge etc.)

Re: RAP-335 ENET0 unusable?

8.4.0.0 with all tunneled, although I doubt that matters much since my issue is even getting the AP up at all.

Any info on what headroom warning is actually about?

the headroom message is a low level bug in packet assembly, it should not be happening - please raise a ticket on it.

Re: RAP-335 ENET0 unusable?

I installed 8.4.0.0 and have this message too on a IAP-305 converted into RAP (right after conversion).

But don't know if it implies issue for the AP as I'm troubleshooting something else.

Re: RAP-335 ENET0 unusable?

Did anoyone find a solution to this? I too am reciving these error messages right after converting an AP to a Remote. 

 

Running 8.4.0.1

 

Thanks.
