Adtran Netvanta 3448 - LLDP error message?

Adtran Netvanta 3448 - LLDP error message?

Adtran Netvanta 3448 - LLDP error message?

Hi there.  I dug out of storage a pair of Netvanta 3448s for a fallback T1 solution.  One of them is connected directly to a Cisco 6506 switch running 12.2(17r)S2 IOS.  Both ethernet ports are set to auto, and they have negotiated 100/full, but the Adtran keeps sending this console message:
2011.12.20 12:20:03 LLDP LLDP:  Speed Duplex mis-match on eth 0/1. Speed/Duplex:"100M/full-duplex"   Neighbor Speed/Duplex: "? duplex"
I found the release notes for AOS 17.09.05 that mentions that this is a known bug, but I am running 18.02.03, and the release notes contain no such bug notice.  Has anyone found a workaround, besides disabling LLDP?

RE: Adtran Netvanta 3448 - LLDP error message?

Update: I contacted Adtran, and they asked for a packet capture of the traffic so that they could correct this issue in the next release of AOS.  They were very helpful and courteous.

RE: Adtran Netvanta 3448 - LLDP error message?

ADTRAN's tech support has always been excellent in this regard from my experience.


RE: Adtran Netvanta 3448 - LLDP error message?

I'm having a similar issue.  Everything I plug into the switch gives them the same error that you're seeing.  

If I unplug a device from a port that's working and plug in my other device, it works fine.  But if I plug my device into an empty port, it doesn't work.  I think I need to reboot the switch.  It seems all empty ports no longer work but ports with something already connected work fine.  This is strange...

RE: Adtran Netvanta 3448 - LLDP error message?

I found this as a know issue in the release notes

"A NetVanta 1638P could intermittently stop passing traffic on some interfaces. A reboot would resolve
the issue."

That could be my issue.  I guess I'll find out when I reboot.
