DGS-6604 m send-lifetime seSh nd-lifetime To set the time period during which an authentication key on a key chain is valid to be sent, use the send-lifetime command in key chain key configuration mode. send-lifetime START-TIME {infinite | END-TIME | duration SECONDS} Syntax Description START-TIME The beginning time that the key specified, by the key command, is valid to be received. The syntax can be either of the following: HH:MM:SS MONTH DATE YEAR HH:MM:SS DATE MONTH YEAR HH-hours MM-minutes SS-seconds MONTH-first three letters of the month DATE-date (1-31) YEAR-year (four digits) infinite END-TIME duration SECONDS The default start time and the earliest acceptable date is January 1, 1993. Key is valid to be sent from the start-time value on and will not expire. Key is valid to be sent from the start-time value until the end-time value.The syntax is the same as that for the START-TIME. The end-time value must be after the start-time value. The default end time is an infinite time period. Length of time (in seconds) that the key is valid to be sent. The range is from 1 to 2147483647 (signed long). Default Command Mode Usage Guideline infinite Key-chain key configuration Specify a start-time value and one of the following values: infinite, end-time, or duration seconds. if lifetimes are to be configured on keys, then it is recommended to use Network Time Protocol (NTP) or another similar time synchronization method. When there are multiple keys that are valid at a time, the first valid key will be used. If there are no valid keys during a specific period of time, then no authentication will be performed.
