The Adaptive Link Layer Discovery Protocol–Media Endpoint Device (Adaptive LLDP-MED) feature delays transmitting LLDP packets at IP phone startup until the system verifies that LLDP messaging is supported. During this period, the voice-VLAN phone configuration is available through valid Cisco Discovery Protocol (CDP) messaging. The duration of the verification is typically about 6 to 30 seconds.
The Adaptive implementation was added to the LLDP-MED feature two reasons:
Some customers enable Cisco Catalyst Port Security features on the Cisco Catalyst switches that do not support LLDP-MED, which may cause switch ports to shut down and the IP phones to be disabled when port security is enabled.
Some legacy Cisco IOS switches do not recognize the LLDP multicast address, which may cause connectivity problems with the IP phones.
The feature affects only the network (switch) port-state machine of the IP phone.
After both CDP and LLDP packets have been received on the SW port, LLDP becomes the preferred protocol. (Even with the Adaptive implementation, some exceptions may cause a port to shut down.)
If the customer’s network configuration does not support LLDP messaging, it is recommended that LLDP be disabled permanently in the Cisco Unified CM Administration application in the Phone Configuration window. Failing to disable LLDP when it is not supported may cause issues for customers that are using older or legacy switches with port security enabled.
To disable LLDP in the Cisco Unified CM Administration application, choose Device > Phone, select the appropriate IP phones, and scroll to the Product Specific Configuration Layout pane.
The Adaptive LLDP-MED feature is supported on the following IP phones:
