Parameters
Description
de: Discards the FR packet whose DE flag bit is 1 when congestion occurs.
ecn: Processes the BECN and FECN flag bits of FR packets when congestion
occurs.
queue-percentage: Network congestion threshold, the occupation ratio of the
interface queue, equal to the percentage of current queue length to the total
queue length of the interface, ranging from 1 to 100. By default, it is 100.
Use the
fr congestion-threshold
function of a FR interface.
Use the
undo fr congestion-threshold
By default, the congestion management function of a FR interface is disabled.
This command is similar to the congestion-threshold command. The difference
is that this command is applied to FR interfaces, while the congestion-threshold
command is applied to FR virtual circuit.
n
The command can only be used for FR DCE interfaces or NNI interfaces.
congestion-threshold.
# Set to process the flag bit of a FR packet when the interface queue length
exceeds 80% of the total length.
