1-8Setting LLDP Operating ModeLLDP can operate in one of the following modes.z TxRx mode. A port in this mode sends and receives LLDPDUs.z Tx mode. A port in this mode only sends LLDPDUs.z Rx mode. A port in this mode only receives LLDPDUs.z Disable mode. A port in this mode does not send or receive LLDPDUs.Follow these steps to set LLDP operating mode:To do… Use the command… RemarksEnter system view system-view —Enter Ethernetinterface viewinterface interface-typeinterface-numberEnter Ethernetinterface view orport group view Enter port groupviewport-group manualport-group-nameRequiredUse either command.Set the LLDP operating mode lldp admin-status { disable| rx | tx | txrx }OptionalTxRx by default.Setting the LLDP Re-Initialization DelayWhen LLDP operating mode changes on a port, the port initializes the protocol state machines after acertain delay. By adjusting the LLDP re-initialization delay, you can avoid frequent initializations causedby frequent LLDP operating mode changes on a port.Follow these steps to set the LLDP re-initialization delay for ports:To do… Use the command… RemarksEnter system view system-view —Set the LLDP re-initializationdelay lldp timer reinit-delay delay Optional2 seconds by defaultEnable LLDP PollingWith LLDP polling enabled, a device checks for the local configuration changes periodically. Upondetecting a configuration change, the device sends LLDPDUs to inform the neighboring devices of thechange.Follow these steps to enable LLDP polling:To do… Use the command… RemarksEnter system view system-view —EnterEthernetinterface viewinterface interface-typeinterface-numberEnter Ethernetinterface viewor port groupview Enter portgroup view port-group manual port-group-nameRequiredUse either command.
