Explanation

VLAN Operating Rules. These rules affect advertisements of VLANs in network policy TLVs: * The VLAN ID TLV subelement applies only to a VLAN configured for voice operation (vlan < * If there are multiple voice VLANs configured on a port, LLDP-MED advertises the voice VLAN having the lowest VID. * The voice VLAN port membership configured on the switch can be tagged or untagged. However, if the LLDP-MED endpoint expects a tagged mem- bership when the switch port is configured for untagged, or the reverse, then a configuration mismatch results. * LLDP-MED provides auto-deployment of layer 2 and layer 3 QoS policies CDP configures only the voice VLAN (IP precedence and COS are hard coded) * The LLDP-MED standard provides support for auto-deployment of streaming multicast and/or video conferencing It supports multiple convergence policies on a given port for plug-and-play deployment with compatible devices (e.g., plug-and-play video surveillance cameras) * LLDP-MED provides detailed IP phone inventory management The Ethernet switch collects model, manufacturing, software, firmware and asset information, since few IP phones and video devices support SNMP * LLDP was designed for easy extensibility Organizationally specific (e.g., LLDP-MED within TIA) and private vendor extensions can be added without concerns of new identifier conflicts to ensure future interoperability * LLDP-MED provides multiple format location information concurrently * LLDP-MED advertises endpoint power priority and backup power conservation This enables future capability for phones and other devices to conserve power and disable non- critical functions to extend battery backup power life during emergency situations
