MED Network Policy An LLDP-MED network policy is a set of configuration settings that is identified by a network policy number. Policies are loaded into LLDP-MED TLVs, and sent to devices connected to the switch. A network policy instructs the connected device as to how to send traffic, for example, a policy can be created for VoIP phones that instructs them to: • Send voice traffic on VLAN 10 • Tag voice traffic with DSCP=63 • Transmit data-traffic to the switch (from the PC connected to the switch through the VoIP phone) without modification to traffic sent by the PC (typically, Untagged). For network policies to be implemented, they must be created and then associated with ports. Before policies are defined, the administrator must create the VLANs, and configure memberships in the VLANs, based on the specification in the LLDP-MED network policies. 540 Dell PowerConnect 55xx Systems User Guide
