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-thresholdcommand to enable congestion management function of FR virtual circuit.

Use the undo congestion-thresholdcommand 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.
