Note
Figure 15-4. Display of Time-Dependent Keys in the Key Chain Entry
Given transmission delays and the variations in the time value from switch to
switch, it is advisable to include some flexibility in the Accept lifetime of the
keys you configure. Otherwise, the switch may disregard some packets
because either their key has expired while in transport or there are significant
time variations between switches.
