Determining the maximum amount of time before client session termination

Procedure
  1. The maximum amount of time between step 2 and step 3 is 180 seconds.
  2. The amount of time between step 3 and step 5 is X seconds.
  3. The reauthentication in step 8 happens less than 180 seconds after step 7, and step 7 happens in 900 seconds after step 5. The maximum amount of time between step 5 and step 8 is 900 + 180 seconds.
  4. The time between step 8 and step 9 is X seconds.
  5. The total time is 180 + X + 900 + 180 + X, which equals 900 +2(180+X) seconds.

NOTE:

The period of 1 to 30 seconds, represented by X, is not a firm time period; the time can vary depending on other 802.1X and web-based/MAC auth parameters.
