de: Discards the FR packet whose DE flag bit is 1 upon congestion.

ecn: Processes the flag bits, BECN and FECN, of FR packet upon congestion.

queue-percentage: Network congestion threshold, the utility ratio of virtual circuit 
queue, namely the percentage of the current queue length of virtual circuit to the 
total queue length, ranging from 1 to 100. By default, it is 100.

Use the congestion-threshold command to enable congestion management 
function of FR virtual circuit.

Use the undo congestion-threshold command to disable this function.

When the percentage of current queue length to the total queue length of virtual 
circuit exceeds the set congestion threshold, it will be regarded that congestion 
occurs on the virtual circuit and congestion management will be performed on 
packets on virtual circuit.

# Set to discard the FR packet whose DE flag bit is 1 concerning the FR class 
named test1, when the current queue length of virtual circuit exceeds 80% of the 
total length.
