• Root Bridge Hello Time: Indicates the designated root bridge's hello time. Hello
information is transmitted every 2 seconds.
• Root Bridge Max Age: Indicates the designated root bridge maximum age, after
which it discards the information as being old and receives new updates.
These variables can be changed using the “priority”, “cost”, “port” and “timers” commands
described later in this chapter.
Example 12-2 illustrates the show stp command with the
ports
parameter. The variables
listed in this example are defined as follows:
• Port# : indicates the port number. Value ranges from 01 to max number of ports in
the switch
• Type : indicates the type of port - TP indicates Twisted Pair
