188 CHAPTER 10: RSTP CONFIGURATION
c Configure Switch C and Switch B to serve as standby of each other and sets
the Bridge priority of Switch C to 8192.
[4500]stp priority 8192
d Enable the Root protection function on every designated port.
[4500]interface Ethernet 1/0/1
[4500-Ethernet1/0/1]stp root-protection
[4500]interface Ethernet 1/0/2
[4500-Ethernet1/0/2]stp root-protection
[4500]interface Ethernet 1/0/3
[4500-Ethernet1/0/3]stp root-protection
RSTP operating mode, time parameters, and port parameters take default
values.
4 Configure Switch D
a Enable RSTP globally.
[4500]stp enable
b The port RSTP defaults are enabled after global RSTP is enabled. You can
disable RSTP on those ports that are not involved in RSTP calculation, however,
be careful and do not disable those involved. (The following configuration
takes Ethernet 1/3 as an example.)
[4500]interface Ethernet 1/3
[4500-Ethernet1/3]stp disable
c Configure the ports (Ethernet 0/1 through Ethernet 0/24) directly connected to
users as edge ports and enables BPDU PROTECTION function. (Take Ethernet
0/1 as an example.)
[4500]interface Ethernet 1/3
[4500-Ethernet1/3]stp edged-port enable
[4500-Ethernet1/3]quit
[4500]stp bpdu-protection
RSTP operating mode, time parameters, and port parameters take default
values.
