RSTP operating mode, time parameters, and port parameters take default
values.
4 Configure Switch D
a Enable RSTP globally.
[SW5500]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 GigabitEthernet 1/3 as an example.)
[SW5500]interface gigabitethernet 1/3
[SW5500-GigabitEthernet1/3]stp disable
c Configure the ports (GigabitEthernet 0/1 through GigabitEthernet 0/24)
directly connected to users as edge ports and enables BPDU PROTECTION
function. (Take GigabitEthernet 0/1 as an example.)
[SW5500]interface gigabitethernet 1/3
[SW5500-GigabitEthernet1/3]stp edged-port enable
[SW5500-GigabitEthernet1/3]quit
[SW5500]stp bpdu-protection
RSTP operating mode, time parameters, and port parameters take default
