Which command do you enter to protect a PortFast-enabled port against unauthorized switches on the network?
A. switch(config)#spanning-tree portfast bpdufilter default
B. switch(config)#spanning-tree portfast bpduguard default
C. switch(config-if)#spanning-tree guard root
D. switch(config-if)#spanning-tree portfast
Carlos,
When enabling “spanning-tree portfast bpduguard default” the ports that you separated with trunk ports will receive this command
“Spanning-tree portfast bpduguard default” enables spanning tree on a global level across all non-trunking ports
“spanning-tree bpduguard enable” enables bpduguard at an interface level
just a curiosity on my CCNA Class I was told: spanning-tree portfast bpduguard enable instead of spanning-tree portfast bpduguard default what of a difference will that be?
