Object

scalar Timeout

This time value, measured in units of hundredths
of a second, controls how fast a port changes its
spanning state when moving towards the Forwarding
state.  The value determines how long the port
stays in each of the Listening and Learning
states, which precede the Forwarding state.  This
value is also used, when a topology change has
been detected and is underway, to age all dynamic
entries in the Forwarding Database.
The delay used by STP Bridges (17.4) to transition 
Root and Designated Ports to Forwarding 
(Table 17-1).

Type Description

A STP timer in units of 1/100 seconds
          
To convert a Timeout value into a value in units of
1/256 seconds, the following algorithm should be used:
          
     b  = floor( (n * 256) / 100)
          
where:
     floor   =  quotient [ignore remainder]
     n is the value in 1/100 second units
     b is the value in 1/256 second units
                                                                                   To convert the value from 1/256 second units back to
1/100 seconds, the following algorithm should be used:
          
     n = ceiling( (b * 100) / 256)
          
where:
      ceiling =  quotient [if remainder is 0], or
                 quotient + 1 [if remainder is non-zero]
      n is the value in 1/100 second units
      b is the value in 1/256 second units
           
 Note: it is important that the arithmetic operations are
 done in the order specified (i.e., multiply first, divide
 second).
