Receiving LLDPDUs An LLDP-enabled port that is operating in TxRx mode or Rx mode checks the validity of TLVs carried in every received LLDPDU. If valid, the information is saved and an aging timer is set for it based on the time to live (TTL) value in the Time to Live TLV carried in the LLDPDU. If the TTL value is zero, the information ages out immediately. Protocols and standards • IEEE 802.1AB-2005, Station and Media Access Control Connectivity Discovery • ANSI/TIA-1057, Link Layer Discovery Protocol for Media Endpoint Devices LLDP configuration task list Complete these tasks to configure LLDP: Task Enabling LLDP Setting the LLDP operating mode Setting the LLDP re-initialization delay Performing basic LLDP configuration Enabling LLDP polling Configuring the advertisable TLVs Configuring the management address and its encoding format Setting other LLDP parameters Setting an encapsulation format for LLDPDUs Configuring CDP compatibility Configuring LLDP to advertise a specific voice VLAN Dynamically advertising server-assigned VLANs through LLDP Configuring LLDP trapping Remarks Required Optional Optional Optional Optional Optional Optional Optional Optional Optional Optional Optional Performing basic LLDP configuration Enabling LLDP To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports. To enable LLDP: Step 1. Enter system view. 2. Enable LLDP globally. 3. Enter Layer 2 Ethernet interface view Command system-view lldp enable interface interface-type interface-number Remarks N/A By default, LLDP is globally enabled. N/A 199
