Weighted Random Early Detection (WRED)
None
This command defines the packet thresholds based on the distributed services code point (DSCP) class value of a packet.
dscp-value
The DSCP value, from 0 to 7.
min-threshold
The minimum threshold in number of packets, from 1 to 4,096. If the minimum threshold is reached, WRED randomly drops some packets with the specified IP precedence.
max-threshold
The maximum threshold in number of packets, from 1 to 4,096. When the threshold is reached, WRED drops all packets with the specified IP precedence.
mark-denominator
Denominator for the fraction of packets dropped when the average queue depth is at the maximum threshold. The default is 10, which means that 1 out of every 10 packets is dropped at the maximum threshold.
