all - All tunnel-abled Layer 2 protocols will be tunneled on the ports. 
threshold - (Optional) Specify the drop threshold for packets-per-second accepted on the 
UNI ports. The ports drop the PDU if the protocol’s threshold is exceeded.  
<value 0-65535> - The range of the threshold value is 0 to 65535 (packet/second). The 
value 0 means no limit. By default, the value is 0.
