Task Default behavior / value
Defining a location ID Not configured
Defining a network policy Not configured
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 183.
NOTE
LLDP-MED is not enabled on ports where the LLDP operating mode is receive only or transmit only.
LLDP-MED is enabled on ports that are configured to both receive and transmit LLDP packets and have
the LLDP-MED capabilities TLV enabled.
Enabling SNMP notifications and Syslog messagesfor LLDP-MED
topology changes
SNMP notifications and Syslog messages for LLDP-MED provide management applications with
information related to topology changes. For example, SNMP notifications can alert the system
whenever a remote Endpoint device is connected to or removed from a local port. SNMP notifications
identify the local port where the topology change occurred, as well as the device capability of the
remote Endpoint device that was connected to or removed from the port.
When you enable LLDP-MED SNMP notifications, corresponding Syslog messages are enabled as
well. When you enable LLDP-MED SNMP notifications, the device will send traps and Syslog messages
when an LLDP-MED Endpoint neighbor entry is added or removed.
SNMP notifications and corresponding Syslog messages are disabled by default. To enable them, enter
a command such as the following at the Global CONFIG level of the CLI.
device(config)#lldp enable snmp med-topo-change-notifications ports e 4/4 to 4/6
Syntax:[no] lldp enable snmp med-topo-change-notifications ports ethernet port-list | all
Changing the fast start repeat count
The fast start feature enables a Network Connectivity Device to initially advertise itself at a faster rate
for a limited time when an LLDP-MED Endpoint has been newly detected or connected to the network.
This feature is important within a VoIP network, for example, where rapid availability is crucial for
applications such as emergency call service location (E911).
The fast start timer starts when a Network Connectivity Device receives the first LLDP frame from a
newly detected Endpoint.
The LLDP-MED fast start repeat count specifies the number of LLDP packets that will be sent during
the LLDP-MED fast start period. By default, the device will send three packets at one-second intervals.
If desired, you can change the number of packets the device will send per second, up to a maximum of
10.
