By default, all optional LLDP information types are included in LLDP transmissions.
LLDP Receive Features
Types of Information Received
When the LLDP receive option is enabled on a port (see “Enabling or Disabling
LLDP” on page 311), 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 G8000 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.
Viewing Remote Device Information
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 G8000 MIB
• Using the G8000 Browser-Based Interface (BBI)
• Using CLI or isCLI commands on the G8000
