Cisco NCS 5500 Series

When time units are used, the guaranteed service rate is used to compute thresholds. The default minimum
threshold is 6 ms and the maximum threshold is 10 ms.
When the value of the units argument is packets, packets are assumed to be 256 bytes in size.
Weighted Random Early Detection
The following restriction apply to Weighted Random Early Detection (WRED):
• For thresholds in time units, the guaranteed service rate is used to calculate the thresholds in bytes.
For bundles, queue limit and WRED thresholds are supported in time units only.

Examples
This example shows how to enable RED using a minimum threshold value of 1000000 and a maximum
threshold value of 2000000:
RP/0/RP0/CPU0:router(config)# policy-map policy1
RP/0/RP0/CPU0:router(config-pmap)# class class1
RP/0/RP0/CPU0:router(config-pmap-c)# random-detect 1000000 2000000
