LLDP MED on 2960X not working

Hi there During testing LLDP-MED signalling to 3rd party phone on catalyst 2960x version 15.2(7)E1 I found, that C2960 sends no LLDP-MED tlv at all (tested with wireshark capture). Only default LLDP tlv are transmitted. According the documentation "Consolidated Platform Configuration Guide, Cisco IOS Release 15.2(7)E" is has to working. Config: network-policy profile 1 voice-signaling vlan 2154 dscp 46 lldp timer 10 lldp run interface GigabitEthernet3/0/23 network-policy 1 switchport access vlan 2261 switchport mode access switchport nonegotiate switchport voice vlan 2154 no cdp enable spanning-tree portfast edge --- Also all lldp commands at interface level are configurable, but NOT shown in the running config and NOT in sh run all!! lldp med-tlv-select network-policy Thanks Regards Gregor

How about with "lldp transmit" and "lldp receive" commands?

Hello Reza

sorry for the confusing formatting. 

If LLDP is enabled globally,  it's also enabled on all interfaces:

 

 

TEST-ACCESS#sh lldp interface gi3/0/23

GigabitEthernet3/0/23:
    Tx: enabled
    Rx: enabled
    Tx state: IDLE
    Rx state: WAIT FOR FRAME

 

Additionally the LLDP config statements are NOT shown in the interface config:

TEST-ACCESS#sh run int gi3/0/23
!
interface GigabitEthernet3/0/23
 network-policy 1
 switchport access vlan 2261
 switchport mode access
 switchport nonegotiate
 switchport voice vlan 2154
 no cdp enable
 spanning-tree portfast edge
end
TEST-ACCESS(config)#int gi3/0/23
TEST-ACCESS(config-if)#lldp transmit
TEST-ACCESS(config-if)#lldp receive
TEST-ACCESS(config-if)#lldp med-tlv-select network-policy
TEST-ACCESS(config-if)#end
TEST-ACCESS#sh run int gi3/0/23
!
interface GigabitEthernet3/0/23
 network-policy 1
 switchport access vlan 2261
 switchport mode access
 switchport nonegotiate
 switchport voice vlan 2154
 no cdp enable
 spanning-tree portfast edge
end

But regular LLDP is working fine all regular LLDP TLVs are send and received.

Thanks and best Gregor
