Creating a filter
Syntax:
no logging filter <name> <sequence> [severity <severity>|event-num <num>|<regexp>] [permit|deny]
Creates a logging filter to restrict which events are logged. The no form of the command removes the logging filter.
<name>: The name that identifies the filter.
severity <severity>: Specifies the severity of an event—major, warning, error, info, or debug.
event-num <num>: Specifies an event number to match.
deny: If the log entry matches the specified criteria, do not log the event message. No further criteria are evaluated for a match.
permit: If the log entry matches the specified criteria, log the event message. No further criteria are evaluated for a match.
