Operation Manual – ACLH3C S5100-SI/EI Series Ethernet Switches Chapter 1 ACL Configuration1-41.2 ACL Configuration1.2.1 Configuring Time RangeTime ranges can be used to filter packets. You can specify a time range for each rule inan ACL. A time range-based ACL takes effect only in specified time ranges. Only after atime range is configured and the system time is within the time range, can an ACL ruletake effect.Two types of time ranges are available:z Periodic time range, which recurs periodically on the day or days of the week.z Absolute time range, which takes effect only in a period of time and does not recur.Note:An absolute time range on an H3C S5100 Series Ethernet Switches can be within therange 1970/1/1 00:00 to 2100/12/31 24:00.I. Configuration ProcedureTable 1-1 Configure a time rangeOperation Command DescriptionEnter system view system-view —Create a timerangetime-range time-name { start-time toend-time days-of-the-week [ fromstart-time start-date ] [ to end-timeend-date ] | from start-time start-date [ toend-time end-date ] | to end-timeend-date }RequiredNote that:z If only a periodic time section is defined in a time range, the time range is activeonly when the system time is within the defined periodic time section. If multipleperiodic time sections are defined in a time range, the time range is active onlywhen the system time is within one of the periodic time sections.z If only an absolute time section is defined in a time range, the time range is activeonly when the system time is within the defined absolute time section. If multipleabsolute time sections are defined in a time range, the time range is active onlywhen the system time is within one of the absolute time sections.z If both a periodic time section and an absolute time section are defined in a timerange, the time range is active only when the periodic time range and the absolutetime range are both matched. Assume that a time range contains an absolute time
