This command sets the low priority or high priority Weighted Random Early Detection (WRED) slope position for the reserved and shared buffer average utilization value where the packet discard probability rises directly to one. The percent parameter is expressed as a percentage of the shared buffer size.
The no form of this command reverts the max-avg value to the default setting. If the current startavg setting is larger than the default, an error occurs and the max-avg value is not changed to the default.
max-avg 90 - High slope default is 90% buffer utilization before discard probability is 1
max-avg 75 - Low slope default is 75% buffer utilization before discard probability is 1
max-avg 75 - Non-tcp slope default is 75% buffer utilization before discard probability is 1
Specifies the percentage of the reserved and shared buffer space for the buffer pool at which point the drop probability becomes 1. The value entered must be greater or equal to the current setting of start-avg. If the entered value is smaller than the current value of start-avg, an error occurs and no change takes place.

This command sets the low priority or high priority Random Early Detection (RED) slope position for the maximum non-one packet discard probability value before the packet discard probability rises directly to one. The percent parameter is expressed as a percentage of packet discard probability where always discard is a probability of 1. A max-prob value of 75 represents 75% of 1, or a packet discard probability of 0.75.
The no form of this command reverts the value to the default.
max-prob 75
Specifies the maximum drop probability percentage corresponding to the max-avg, expressed as a decimal integer.

This command enables or disables the administrative status of the Random Early Detection slope.
By default, all slopes are shutdown and have to be explicitly enabled (no shutdown).
The no form of this command administratively enables the RED slope.

This command sets the low priority or high priority Random Early Detection (RED) slope position for the shared buffer average utilization value where the packet discard probability starts to increase above zero. The percent parameter is expressed as a percentage of the shared buffer size.
The no form of this command reverts the value to the default. If the max-avg setting is smaller than the default, an error occurs and the start-avg setting is not changed to the default.
max-avg 70 - High slope default is 70% buffer utilization
max-avg 50 - Low slope default is 50% buffer utilization
max-avg 50 - Non-tcp slope default is 50% buffer utilization
Specifies the percentage of the reserved and shared buffer space for the buffer pool at which the drop starts. The value entered must be lesser or equal to the current setting of max-avg. If the entered value is greater than the current value of max-avg, an error occurs and no change takes place.
