To quickly configure BPDU protection on Switch 2, copy the following commands and
paste them into the switch terminal window:
[edit]
set protocols rstp interface ge-0/0/5 edge
set protocols rstp interface ge-0/0/6 edge
set protocols rstp bpdu-block-on-edge
To configure BPDU protection:
Configure interface ge-0/0/5
1.
[edit protocols rstp]
user@switch# set interface ge-0/0/5 edge
user@switch#set interface ge-0/0/6 edge
Configure BPDU protection on all edge ports:
2.
[edit protocols rstp]
user@switch# set bpdu-block-on-edge
Check the results of the configuration:
user@switch> show configuration protocols rstp
interface ge-0/0/5.0 {
edge;
}
interface ge-0/0/6.0 {
edge;
}
bpdu-block-on-edge;
To confirm that the configuration is working properly:
Displaying the Interface State Before BPDU Protection Is Triggered on page 1563
Verifying That BPDU Protection is Working Correctly on page 1564
Displaying the Interface State Before BPDU Protection Is Triggered
Before BPDUs are being received from the PCs connected to interface
interface , confirm the interface state.
ge-0/0/6
Use the operational mode command:
user@switch> show spanning-tree interface
Spanning tree interface parameters for instance 0
