duration < mm/dd/yy [ yy ] hh:mm:ss | seconds > 
Specifies the time period during which the switch 
can use this key to authenticate inbound packets. 
Duration is either an end date and time or the 
number of seconds to allow after the start date and 
time (which is the accept-lifetime setting). 
send-lifetime <mm/dd/yy[yy] hh:mm:ss | now> 
Specifies the start date and time of the valid period 
in which the switch can transmit this key as 
authentication for outbound packets. 
duration < mm/dd/yy[yy] hh:mm:ss | seconds > 
Specifies the time period during which the switch 
can use this key to authenticate outbound packets. 
Duration is either an end date and time or the 
number of seconds to allow after the start date and 
time (which is the accept-lifetime setting). 
show key-chain < chain_name > 
Displays the detail information about the keys used 
in the key chain named < chain_name >. 
Note  Using time-dependent keys requires that all the switches have accurate, 
synchronized time settings. You can manually set the time or use the Time 
protocol feature included in the switches. For more information, refer to the 
chapter covering time protocols in the Management and Configuration 
Guide for your switch.
