IEEE Std802.1Qaz-2011 (standard version) isused as the initial version for negotiationat the local end.Configuring LLDP trapping and LLDP-MED trappingLLDP trapping or LLDP-MED trapping notifies the network management system of events such as newlydetected neighboring devices and link failures.To prevent excessive LLDP traps from being sent when the topology is unstable, set a trap transmissioninterval for LLDP.To configure LLDP trapping and LLDP-MED trapping:Step Command Remarks1.
