Note Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) LLDP-MED operation requires the macphy_config TLV subelement-enabled by default-that is optional for IEEE 802.1AB LLDP operation. Refer to the dot3TlvEnable macphy_config command on page 13-55. Network Policy Advertisements. Network policy advertisements are intended for real-time voice and video applications, and include these TLV subelements: ■ Layer 2 (802.1p) QoS ■ Layer 3 DSCP (diffserv code point) QoS ■ Voice VLAN ID (VID) 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 < vid > voice). ■ 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 membership when the switch port is configured for untagged, or the reverse, then a configuration mismatch results. (Typically, the endpoint expects the switch port to have a tagged voice VLAN membership.) ■ If a given port does not belong to a voice VLAN, then the switch does not advertise the VLAN ID TLV through this port. Policy Elements. These policy elements may be statically configured on the switch or dynamically imposed during an authenticated session on the switch using a RADIUS server and 802.1X or MAC authentication. (Web authentication does not apply to VoIP telephones and other telecommunications devices that are not capable of accessing the switch through a Web browser.) The QoS and voice VLAN policy elements can be statically configured with the following CLI commands: vlan < vid > voice vlan < vid > < tagged | untagged > < port-list > int < port-list > qos priority < 0 - 7 > vlan < vid > qos dscp < codepoint > 13-61
