LLDP-MED attributes advertised by the Dell PowerConnect device
24
• voice – For use by dedicated IP telephony handsets and similar devices that support
interactive voice services.
• voice-signaling – For use in network topologies that require a different policy for voice signaling
than for voice media. Note that this application type should not be advertised if all the same
network policies apply as those advertised in the voice policy TLV.
• tagged vlan <vlan id> specifies the tagged VLAN that the specified application type will use.
• untagged indicates that the device is using an untagged frame format.
• priority-tagged indicates that the device uses priority-tagged frames. In this case, the device
uses the default VLAN (PVID) of the ingress port.
• priority <0 –7> indicates the Layer 2 priority value to be used for the specified application type.
Enter 0 to use the default priority.
• dscp <0 – 63> specifies the Layer 3 Differentiated Service codepoint priority value to be used
for the specified application type. Enter 0 to use the default priority.
For <port-list>, specify the ports in one of the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually. Note that using the keyword all may cause undesirable
effects on some ports. For example, if you configure all ports to advertise their VLAN name, and
the configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
LLDP-MED attributes advertised by the Dell PowerConnect device
LLDP-MED attributes are only advertised on a port if LLDP-MED is enabled (which is done by
enabling the LLDP-MED capabilities TLV), the port operating mode is receive and transmit (the
default), and the port has received an LLDP-MED advertisement from an Endpoint. By default, the
Dell PowerConnect device will automatically advertise the following LLDP-MED attributes when the
above criteria are met:
• LLDP-MED capabilities
• Location ID
• Network policy
NOTE
Although the Location ID and Network policy attributes are automatically advertised, they will have
no effect until they are actually defined.
LLDP-MED capabilities
When enabled, LLDP-MED is enabled, and the LLDP-MED capabilities TLV is sent whenever any
other LLDP-MED TLV is sent. When disabled, LLDP-MED is disabled and no LLDP-MED TLVs are
sent.
The LLDP-MED capabilities advertisement includes the following information:
• The supported LLDP-MED TLVs
