MIB support
If the TTL field value is zero, the receiving LLDP agent is notified that all system information
associated with the LLDP agent/port is to be deleted. This TLV may be used, for example, to signal
that the sending port has initiated a port shutdown procedure.
The LLDPDU format is shown in “LLDPDU packet format” on page 453.
The TTL TLV format is shown below.

Syslog messages for LLDP provide management applications with information related to MIB data
consistency and general status. These Syslog messages correspond to the lldpRemTablesChange
SNMP notifications. Refer to “Enabling LLDP SNMP notifications and Syslog messages” on
page 462.
Syslog messages for LLDP-MED provide management applications with information related to
topology changes. These Syslog messages correspond to the lldpXMedTopologyChangeDetected
SNMP notifications. Refer to “Enabling SNMP notifications and Syslog messages for LLDP-MED
topology changes” on page 475.
