CURVE
red-curve
Overview Use this command to allow configuration of a RED (Random Early Discard) curve
template.
Use the no variant of this command to set the RED curve back to the default.
Syntax red-curve < red-curve-name > [limit < 4-127 >] [avpkt < 64-1518 >]
[min < 3-126 >] [max < 4-127 >] [probabilty < 1-100 >]

[ecn [ecn-drop]]
no red-curve [< red-curve-name >]
Default The default RED curve is red-curve default limit 127 avpkt 576B min 10 max 32
prob 2 .
Mode Traffic-control
Usage The RED curve template can later be applied to a traffic control class, sub-class, or
sub-sub-class.
Example To configure a RED curve with ECN dropping and the default curve shape, use the
commands:
awplus# configure terminal
awplus(config)# traffic-control
awplus(config-tc)# red-curve red-ecn ecn
Parameter Description
<red-curve-name>
The RED curve name.
limit < 4-127 >
The hard queue length limit (in packets) for the RED curve. Once the queue
length reaches the limit, all packets are dropped.
avpkt <64-1518>
The average packet size to use for queue size calculations in bytes.
min <3-126>
The minimum queue length for random early discard (in packets). Between
<min> and <max> the drop probability will increase linearly.
max <4-127>
The maximum queue length where packets are probabilistically dropped. At
<max> the drop probability equals <probability>. Beyond <max> the drop or
marking probability is 100%.
probability <1-100>
The probability of a packet being dropped when queue-length reaches <max>.
The drop probability increases linearly from 0 to <probability> in between
<min> and <max>.
ecn
Use explicit congestion notification marking instead of dropping the packet.
ecn-drop
When average queue size exceeds <max> drop packets instead of marking.
