Benefits of LLDP-MED
LLDP-MED provides the following benefits:
• Vendor-independent management capabilities, enabling different IP telephony systems to
interoperate in one network.
• Automatically deploys network policies, such as Layer 2 and Layer 3 QoS policies and Voice
VLANs.
• Supports E-911 Emergency Call Services (ECS) for IP telephony
• Collects Endpoint inventory information
• Network troubleshooting
• Helps to detect improper network policy configuration
LLDP-MED Network Connectivity Devices
(e.g., L2/L3 switch, bridge, etc.) provide IEEE
802 network access to LLDP-MED endpoints
LLDP-MED Generic Endpoints (Class I)
act as basic participants in LLDP-MED.
Example Class I device: Communications
controller
LLDP-MED Media Endpoints
(Class II) support IP media
streams.
Example Class II devices:
media gateway, conference
bridge
LLDP-MED Comunication Device Endpoints
(Class III) support end user IP communication.
Example Class III devices: IP telephone,
softphone
IP Network
