13.
Argument Description
hello-time The time interval, in seconds, between BPDU transmissions from the ports of this unit.
The default value is 2 seconds.
rapid-spanning-tree forward-delay
The rapid-spanning-tree forward-delay command, in Protocol Configuration mode, sets the
time, in seconds, that the switch stays in each of the Listening and Learning states that
precede the Forwarding State. In addition, when a topology change is underway and has been
detected, this parameter is used to age all dynamic entries in the Forwarding database. The
default value is 15 seconds, and the range is depends on the MaxAge value (between 4 and
30 seconds). The no form of this command resets to the default value.
NOTE
You cannot assign forward-delay a value less than MaxAge/2+1.
Command Syntax
device-name(cfg protocol)#rapid-spanning-tree forward-delay <forward-delay>
device-name(cfg protocol)#no rapid-spanning-tree forward-delay
Argument Description
forward- The time, in seconds, that the switch stays in each of the Listening and Learning
delay states that precede the Forwarding State. The default value is 15 seconds.
rapid-spanning-tree max-age
The rapid-spanning-tree max-age command, in Protocol Configuration mode, sets the time
in seconds that learned Rapid Spanning Tree information is kept before being discarded. The
default value is 20 seconds, and the range depends on the hello-time and forward- delay
values (between 4 and 30 seconds. The no form of this command resets to the default value.
NOTE
You cannot assign MaxAge a value that is less than 2*(hello-time + 1) or more than
2*(forward-delay – 1).
Command Syntax
device-name(cfg protocol)#rapid-spanning-tree max-age <6-28>
device-name(cfg protocol)#no rapid-spanning-tree max-age
Argument Description
6-28 The time, in seconds, during which learned Spanning Tree information is kept before being
discarded. The default value is 20 seconds.
