Syslog messages

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. Refer to

“Enabling LLDP SNMP notifications and syslog messages”

on

page 197.

Configuring LLDP

This section describes how to enable and configure LLDP.

Table 42

lists the LLDP global-level tasks and the default behavior/value for each task.

Configuration notes and considerations

LLDP is supported on Ethernet interfaces only.

If a port is 802.1X-enabled, the transmission and reception of LLDP packets will only take
place while the port is authorized.

Cisco Discovery Protocol (CDP) and Brocade Discovery Protocol (FDP) run independently of
LLDP. Therefore, these discovery protocols can run simultaneously on the same device.

Enabling and disabling TLV advertisements

system description, VLAN name, and power-via-MDI
information, which may be configured by the system
administrator.
Also, if desired, you can disable the advertisement of
individual TLVs.
