When the LLDP receive option is enabled on a port (see "Enabling or Disabling
LLDP" on page 491), the port may receive the following information from
LLDP‐capable remote systems:
 Chassis Information
 Port Information
 LLDP Time‐to‐Live
 Port Description
 System Name
System Description

 System Capabilities Supported/Enabled
Remote Management Address

The CN4093 stores the collected LLDP information in the MIB. Each remote
LLDP‐capable device is responsible for transmitting regular LLDP updates. If the
received updates contain LLDP information changes (to port state, configuration,
LLDP MIB structures, deletion), the switch will set a change flag within the MIB for
convenient notification to SNMP‐based management systems.
Note: In stacking mode, both the Master and the Backup receive LLDP information
for all the ports in a stack and update the LLDP table. The Master and Backup
switches synchronize the LLDP tables.
LLDP information collected from neighboring systems can be viewed in numerous
ways:
Using a centrally‐connected LLDP analysis server

 Using an SNMP agent to examine the CN4093 MIB
 Using the CN4093 Browser‐Based Interface (BBI)
 Using CLI or isCLI commands on the CN4093
Using the isCLI the following command displays remote LLDP information:
CN4093(config)# show lldp remote­device [<index number>]
