Configuring LLDP-MED
24
The maximum frame size advertisement will appear similar to the following on the remote device,
and in the CLI display output on the Dell PowerConnect device (show lldp local-info).
Maximum frame size: 1522 octets
Syntax: [no] lldp advertise max-frame-size ports ethernet <port-list> | all
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.
Configuring LLDP-MED
This section provides the details for configuring LLDP-MED.
Table 124 lists the global and interface-level tasks and the default behavior/value for each task.
Enabling LLDP-MED
When LLDP is enabled globally, LLDP-MED is enabled if the LLDP-MED capabilities TLV is also
enabled. By default, the LLDP-MED capabilities TLV is automatically enabled. To enable LLDP,
refer to “Enabling and disabling LLDP” on page 693.

Changing the Fast Start Repeat Count The system automatically sets the fast start repeat count to
3 when a Network Connectivity Device receives an LLDP
packet from an Endpoint that is newly connected to the
network.
NOTE: The LLDP-MED fast start mechanism is only intended
to run on links between Network Connectivity devices
and Endpoint devices. It does not apply to links
between LAN infrastructure elements, including
between Network Connectivity devices, or to other
types of links.
