Cisco 3650 IOS XE 3.6.0 - LLDP is not working correctly

[mlinder01]

Dear All,

We have a very strange issue with the new release for the Cisco 3650/3850 Switches IOS XE 3.6.0.

Setup:

- Cisco 3650 48 Port PoE Switch with Nortel/Snom Phones attached

with IOS XE 3.3.0

- Everything is working correctly the phones get their Voice-VLAN etc.

with IOS XE 3.6.0

- LLDP is not working correctly the phone get the message "No LLDPDU's received"

but if on IOS XE 3.6.0 the debug command "debug lldp states" is active everything is working...

I found nothing in the Web and in the Bug-Toolkit...

Many thanks for any help,

Manuel
