To configure L2PT on an EX Series switch:
Because L2PT operates under the Q-in-Q tunneling configuration, you must enable
1.
Q-in-Q tunneling before you can configure L2PT. Enable Q-in-Q tunneling on VLAN
:
customer-1
[edit]
user@switch# set vlans customer-1 dot1q-tunneling
Enable L2PT for the Layer 2 protocol you want to tunnel, on the VLAN:
2.
To enable L2PT for a specific protocol (here, STP):
[edit]
user@switch# set vlans customer-1 dot1q-tunneling layer2-protocol-tunneling stp
To enable L2PT for all supported protocols:
[edit]
user@switch# set vlans customer-1 dot1q-tunneling layer2-protocol-tunneling all
(Optional) Configure the drop threshold:
3.
NOTE: If you also configure the shutdown threshold, ensure that you
configure the drop threshold value to be less than or equal to the shutdown
threshold value. If the drop threshold value is greater than the shutdown
threshold value and you to try to commit the configuration changes, the
commit will fail.
[edit]
user@switch# set vlans customer-1 dot1q-tunneling layer2–protocol-tunneling stp
drop-threshold 50
(Optional) Configure the shutdown threshold:
4.
NOTE: If you also configure the drop threshold, ensure that you configure
the shutdown threshold value to be greater than or equal to the drop
threshold value. If the shutdown threshold value is less than the drop
threshold value and you to try to commit the configuration changes, the
commit will fail.
[edit]
user@switch# set vlans customer-1 dot1q-tunneling layer2–protocol-tunneling stp
shutdown-threshold 100
NOTE: Once an interface is disabled, you must explicitly reenable it using
the clear ethernet-switching layer2-protocol-tunneling error
Otherwise, the interface remains disabled.
