NETGEAR 8800 Chassis Switch CLI Manual When the add keyword is used, the specified event name is added to the beginning of the filter item list maintained for this filter. The new filter item either includes the events specified, or if the exclude keyword is present, excludes the events specified. The delete keyword is used to remove events from the filter item list that were previously added using the add command. All filter items currently in the filter item list that are identical to, or a subset of, the set of events specified in the delete command will be removed. Event Filtering Process From a logical standpoint, the filter associated with each enabled log target is examined to determine whether a message should be logged to that particular target. The determination is made for a given filter by comparing the incident with the most recently configured filter item first. If the incident matches this filter item, the incident is either included or excluded, depending on whether the exclude keyword was used. Subsequent filter items on the list are compared if necessary. If the list of filter items has been exhausted with no match, the incident is excluded. Events, Components, and Subcomponents As mentioned, a single event can be included or excluded by specifying the event's name. Multiple events can be added or removed by specifying a NETGEAR 8800 component name plus an optional severity. Some components, such as BGP, contain subcomponents, such as Keepalive, which is specified as BGP.Keepalive. Either components or subcomponents can be specified. The keyword all in place of a component name can be used to indicate all NETGEAR 8800 components. Severity Levels When an individual event name is specified following the events keyword, no severity value is needed since each event has pre-assigned severity. When a component, subcomponent, or the all keyword is specified following the events keyword, a severity value is optional. If no severity is specified, the severity used for each applicable subcomponent is obtained from the pre-assigned severity threshold levels for those subcomponents. For example, if STP were specified as the component, and no severity is specified for the add of an include item, then only messages with severity of error and greater would be passed, since the threshold severity for the STP component is error. If STP.InBPDU were specified as the component, and no severity is specified, then only messages with severity of warning and greater would be passed, since the threshold severity for the STP.InPBDU subcomponent is warning. Use the show log components command to see this information. The severity keyword all can be used as a convenience when delete or exclude is specified. The use of delete (or exclude) with severity all deletes (or excludes) previously added events of the same component of all severity values. Note: If no severity is specified when delete or exclude is specified, severity all is used 338 | Chapter 8. Commands for Status Monitoring and Statistics
