# To configure Switch C as a secondary root, you can either configure the Bridge
priority of it as 4096 or simply use the command to specify it as the secondary root.
z Set the Bridge priority of Switch C to 4096
[Quidway] stp priority 4096
z Designate Switch C as the root, using the following command.
[Quidway] stp root secondary
# Enable the Root protection function on every designated port.
[Quidway] interface ethernet 0/1
[Quidway-Ethernet0/1] stp root-protection
[Quidway] interface ethernet 0/2
[Quidway-Ethernet0/2] stp root-protection
[Quidway] interface ethernet 0/2
[Quidway-Ethernet0/2] stp root-protection
# RSTP operating mode, time parameters, and port parameters take default values.
3) Configure Switch D
# Enable RSTP globally.
[Quidway] stp enable
# 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 0/4 as an
example.)
[Quidway] interface ethernet 0/4
[Quidway-Ethernet0/4] stp disable
# 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.)
[Quidway] interface ethernet 0/1
[Quidway-Ethernet0/1] stp edged-port enable
[Quidway-Ethernet0/1] quit
