187Configuring LLDP trappingLLDP trapping notifies the network management system (NMS) of events such as newly-detectedneighboring devices and link malfunctions.LLDP traps are sent periodically, and the interval is configurable. To prevent excessive LLDP traps frombeing sent when the topology is unstable, set a trap transmit interval for LLDP.Follow these steps to configure LLDP trapping:To do… Use the command… RemarksEnter system view system-view —Enter Layer 2 Ethernetinterface view interface interface-type interface-numberEnter Ethernetinterface viewor port groupview Enter port group view port-group manual port-group-nameRequiredUse either command.Enable LLDP trapping lldp notification remote-change enable RequiredDisabled by default.Return to system view quit —Set the LLDP trap transmit interval lldp timer notification-interval interval Optional5 seconds by default.Displaying and maintaining LLDPTo do… Use the command… RemarksDisplay the global LLDPinformation or the informationcontained in the LLDP TLVs to besent through a portdisplay lldp local-information [ global | interfaceinterface-type interface-number ] [ | { begin | exclude| include } regular-expression ]Available in anyviewDisplay the information containedin the LLDP TLVs sent fromneighboring devicesdisplay lldp neighbor-information [ brief | interfaceinterface-type interface-number [ brief ] | list[ system-name system-name ] ] [ | { begin | exclude |include } regular-expression ]Available in anyviewDisplay LLDP statisticsdisplay lldp statistics [ global | interfaceinterface-type interface-number ] [ | { begin | exclude| include } regular-expression ]Available in anyviewDisplay LLDP status of a portdisplay lldp status [ interface interface-typeinterface-number ] [ | { begin | exclude | include }regular-expression ]Available in anyviewDisplay types of advertisableoptional LLDP TLVsdisplay lldp tlv-config [ interface interface-typeinterface-number ] [ | { begin | exclude | include }regular-expression ]Available in anyview
