Configure the shutdown threshold as
4.
[edit]
user@switch# set vlans customer-1 dot1q-tunneling layer2–protocol-tunneling stp
shutdown-threshold 100
Check the results of the configuration:

user@switch# show vlans customer-1 dot1q-tunneling
layer2-protocol-tunneling {
stp {
drop-threshold 50;
shutdown-threshold 100;
}
}
To verify that L2PT is working correctly, perform this task:
Verify That L2PT Is Working Correctly on page 1595
Verify That L2PT Is Working Correctly
Verify that Q-in-Q tunneling and L2PT are enabled.
Check to see that Q-in-Q tunneling and L2PT are enabled on each PE device (Switch A
and Switch D are the PE devices):

Check to see that L2PT is tunneling STP on VLAN
and shutdown-threshold have been configured:
user@switchA> show ethernet-switching layer2-protocol-tunneling vlan customer-1

Check the state of the interfaces on which L2PT has been enabled, including what kind
of operation (encapsulation or decapsulation) they are performing:
