The TTL value is automatically computed based on the LLDP configuration settings. The TTL value
will appear similar to the following on the remote device, and in the CLI display output on the
Brocade device (show lldp local-info).
Time to live: 40 seconds
•
If the TTL field has a value other than zero, the receiving LLDP agent is notified to completely
replace all information associated with the LLDP agent or port with the information in the
received LLDPDU.
•
If the TTL field value is zero, the receiving LLDP agent is notified that all system information
associated with the LLDP agent or 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 250.
The TTL TLV format is shown below.

MIB support
Brocade devices support the following standard MIB modules:
•
LLDP-MIB
•
LLDP-EXT-DOT1-MIB
•
LLDP-EXT-DOT3-MIB
Syslog messages
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.
Configuring LLDP
This section describes how to enable and configure LLDP.
Table 59
lists the LLDP global-level tasks and the default behavior/value for each task.
