I am struggling with an issue here for quite some time now. I have a 3750X switch with LLDP configured to send a network policy to advertise a voice vlan to IP phones. However on some ports I cant get it to send out any LLDP packets, so the connected Phone does not end up in the voice VLAN.
This is my config:
network-policy profile 1
voice vlan 1130
interface range gi1/0/1-10,gi1/0/12,gi1/0/14-18,gi1/0/20-21, gi1/0/23-27
auto qos voip trust
mls qos trust dscp
I have tried shutting and no shutting the port (also waiting for the holdtimer of 120 seconds to time out). Also adjusting the lldp timer to 5 seconds. Clearing the LLDP table. Changing the access vlan on the port. Nothing seems to help.
In my wireshark traces I see that when the switchport comes up, the switch immediately starts sending lldp messages and advertising the network policy attribute with the correct VLAN for all working phones. For the none working phones I see only the Phone sending packets and not the switch.
