Availability: Redundant Hardware Resilient Networks Modular Operating Systems from Edge-to-Core 2. Performance Independent from network usage and enabled functions 3. Interconnectivity: Ethernet NNI: to guarantee QoS when interconnecting to other networks 4. Manageability 5. Security

Administrator configures VoIP policies. Policy includes VoIP VLAN, Dot1p priority 2. Administrator pushes policy to switch 3. After 802.1x auth, phone sends LLDP message with model, PoE needs, serial number,... 4. Switch configures VLAN, Dot1p priority, ACLs and PoE on the port 5. Switch pushes VLAN, Call-Server, E911 location,QoS, etc to the phone
