Configuring Security, Quality, and Network Features Configuring VLAN Settings 5 LLDP-MED and Multiple Network Devices If the same application type is used for network policy but different Layer 2 or Layer 3 QoS Network policies are received by the phones from multiple network connectivity devices, the last valid network policy is honored. To ensure deterministic and consistent of Network Policy, multiple network connectivity devices should not send out conflicting network policies for the same application type. LLDP-MED and IEEE 802.X The phones do not support IEEE 802.X and will not work in a 802.1X wired environment. However, IEEE 802.1X or Spanning Tree Protocols on network devices could result in delay of fast start response from switches. Configuring the VLAN Settings To configure VLAN settings, navigate to Admin Login > advanced > Voice > System. Under VLAN Settings, configure the following parameters: Parameter Enable VLAN VLAN ID PC Port VLAN Highest Priority Description Choose Yes to enable VLAN. Choose no to disable. If you use a VLAN without Cisco Discovery Protocol (CDP) (VLAN enabled and CDP disabled), enter a VLAN ID for the IP phone. Note that only voice packets are tagged with the VLAN ID. Do not use 1 for the VLAN ID. Choose No Limit, or 0-7 (default 0). The highest priority is 7. The priority applied to all frames, tagged and untagged. The phone modifies the frame priority only if the incoming frame priority is higher than this value. Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide 148
