Syntax congestion-threshold { de | ecn } queue-percentage
undo congestion-threshold { de | ecn }
View Frame relay class view
Parameters 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.
Description 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.
Related commands: fr congestion-threshold.
Examples # 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.
