RE: T46G LLDP-MED VLAN Issue
I have been experiencing this issue as well on Cisco 3560 switches. I have the following configuration:

lldp run (in global)

interface FastEthernetx/x
switchport access vlan 210
switchport mode access
switchport voice vlan 98
spanning-tree portfast

The vlan is always correct, however on occasion, the phone dhcp's on the native vlan (210 in this case), so it routes to nowhere. Since this happens randomly, I'm assuming it has to do with some kind of timing issue, and my guess is it's related to the lldp timer, which I have now reduced by setting 'lldp timer 5' in global settings.

I am using a T46G running 28.73.0.45 We have also seen this with T48G. Also a possibility, it may only happen with a PC connected to the passthrough port, since this is the only scenario I have seen this occur.
