I found that I was able to get the LLDP-MED packets flowing by performing the following steps:
When building a new config:
1) Enable LLDP from the Global Config CLI: lldp run
2) Create a network-policy profile for the voice vlan (in my example, the voice vlan is 123):
network-policy profile 123
voice vlan 123
voice-signaling vlan 123
3) Apply the voice vlan to the applicable switchport interface(s)
When adding to an existing config:
1) Enable LLDP from the Global Config CLI: lldp run
2) Create a network-policy profile for the voice vlan (in my example, the voice vlan is 123):
network-policy profile 123
voice vlan 123
voice-signaling vlan 123
3) Apply the network-policy to the switchport interface(s)
int g0/10
network-policy 123
lldp med-tlv-select network-policy
Note: This will remove any pre-existing voice vlan from the interface(s).
At this point, the LLDP-MED packets should start flowing between the IP phone and switch. However, in my case this didn't happen. I had to remove the network-policy that I had just applied to the interface and re-apply the voice vlan. For some reason (at least in my setup), the LLDP process did not trigger with the applying of the network-policy. It would only work after I applied the network-policy to the interface, removed the network-policy from the interface, then re-applied the voice vlan to the interface. I have a TAC case open regarding this at the moment and will post my findings if applicable.
Hope this helps any other newbies who may have experienced anything similar to this.
