How to set up and manage LLDP MED on Dell Networking X Series switches.

Article Content

Instructions

Article Description: This article discusses the configuration options available using LLDP MED on Dell Networking X Series switches.


Objectives
 
  1. LLDP MED Overview
  2. Adding MED Network Policy
  3. MED Port Settings
 

LLDP MED Overview

 
A network policy instructs the connected media endpoint devices 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.

Adding MED Network Policy

 
To add  a MED network policy:
 
1   Click Network Administration > Link Layer Discovery Protocol (LLDP) > MED Network Policy.
 
Previously-defined network policies are displayed.

2   Click Edit, Add, and enter the fields:
 
– Network Policy Number — Select an available network policy number.
– Application — Select the application (type of traffic) for which the network policy is defined.
– VLAN ID — Enter the VLAN ID to which the traffic should be sent.
– VLAN Type —Select whether the traffic is Tagged or Untagged.
– User Priority — Select the traffic priority assigned to the network application.
– DSCP Value — Select the value to be used by neighbors to mark the traffic sent to the switch.

 
MED Port Settings

 
To assign MED network policies to ports:
 
1   Click Network Administration > Link Layer Discovery Protocol (LLDP) > MED Port Settings.
 
2   The following fields are displayed for each port:
 
– LLDP MED Status — Specifies if LLDP-MED is enabled on the selected port.
– Network Policy — Specifies whether a network policy is assigned to the port.
– Location — Specifies whether the location is advertised.
– PoE — Specifies whether PoE is enabled on the port

3   To modify network policies on a port, click Edit.
 
4   Select the port to be configured, and enter the fields for the port:
 
– Enable LLDP-MED — Enable/disable LLDP-MED on the port.
– Available TLVs — Contains a list of available TLVs that can be advertised by the port.

The possible options are:
 
  • Network Policy — Advertises the network policy attached to the port.
  • Location — Advertises the port’s location.
 
Move the TLVs to be published to the Tx Optional TLVs list.
 
– Available Network Policy — Contains a list of network policies that can be assigned to a port. Move the network policies to be assigned to the port to the Network Policy list.
– Location Coordinate — Enter the device’s location map coordinates.
– Location Civic Address — Enter the device’s civic or street address location, for example 414 23rd Ave E.
– Location ECS ELIN — Enter the device’s ECS ELIN location.

 
5   To view MED details for a port, return to the main page and click the Detail icon of the selected port.

The following fields are displayed for the port:
 
– Auto-Negotiation Status — Enabled specifies that auto-negotiation is enabled on the port; Disabled indicates that it is not.
– Advertised Capabilities — The list of port capabilities advertised for the port.
– MAU Type — The Media Attachment Unit type. The MAU performs physical layer functions, including digital data conversion from the Ethernet interfaces' collision detection and bit injection into the
network, for example, 100BASE-TX full duplex mode.
– System Name — The system's assigned name (in alpha-numeric format). This value equals the sysName object.
– System Description — A description of the network entity (in alphanumeric format). This includes the system's name and versions of the hardware, operating system, and networking software supported by the switch. This value equals the sysDescr object.
– Device ID — The device ID advertised, for example, the device MAC address.
– Device Type — The type of device.
– LLDP MED Capabilities — The TLVs that are advertised by the port.
– LLDP MED Device Type — Specifies whether a sender is a network connectivity device or an endpoint device.
– Application — The following fields are displayed for each possible application type:
 
  • Application Type — The application type.
  • Flags — The VLAN tagging status for the application type:
Tagged or Untagged.
  • VLAN ID — The VLAN number for the application type.
  • User Priority — The user priority for the application type.
  • DSCP — The DSCP value assigned to the network policy.
     
– Location Type — Displays the port’s LLDP location type:
 
  • Coordinates — Device’s location map coordinates.
  • Civic Address — Device’s civic or street address location, for example 414 23rd Ave E.
  • ECS ELIN — Device’s ECS ELIN location.
     
– Location Address — Displays the port’s LLDP location, according to the Location Type.
