HAPTER
spanning-tree
hello-time
C U
OMMAND SAGE
This command sets the maximum time (in seconds) a port will wait before
changing states (i.e., discarding to learning to forwarding). This delay is
required because every device must receive information about topology
changes before it starts to forward frames. In addition, each port needs
time to listen for conflicting information that would make it return to the
discarding state; otherwise, temporary data loops might result.
