For more information, see the sections for each module.To generate Linkup or Linkdown traps when the link state of an interface changes, you must enable thelinkUp or linkDown trap function globally by using the snmp-agent trap enable [ standard [ linkdown |linkup ] * ] command and on the interface by using the enable snmp trap updown command.Related commands: snmp-agent target-host and enable snmp trap updown.Examples# Enable the device to send SNMP authentication failure traps to 10.1.1.1 in the community name public. system-view[Sysname] snmp-agent target-host trap address udp-domain 10.1.1.1 params securitynamepublic[Sysname] snmp-agent trap enable standard authenticationsnmp-agent trap if-mib link extendedSyntaxsnmp-agent trap if-mib link extendedundo snmp-agent trap if-mib link extendedViewSystem view
