Differential Class Group - HP procurve 8100fl series Management And Configuration Manual

For example, if you want to invoke WRED when the queue is approximately
25% full, assign the drop probability to 1 when the queue is approximately 75%
full, and drop all packets when the queue is completely full (drop probability
is 100%), you would enter:
ProCurve(config-spomap-dc)#random-detect 64 192 100

Differential Class Group

To configure differentiated class groups, enter from Special Output Map mode
ProCurve(config-spomap)#diff-group <diff-class group>
There are five diff-class groups:
af1x—Assured Forwarding Class 1
■
■ af2x—Assured Forwarding Class 2
af3x—Assured Forwarding Class 3
■
df —Default Forwarding Class (aka best effort)
■
■ ef—Expedited Forwarding Class (aka priority)
To configure Assured Forwarding Class 3 as the diff-class group, enter:
ProCurve(config-spomap)#diff-group af3x
In the differentiated class group mode, you can use the bandwidth command
to configure guaranteed bandwidth for traffic in this diff-class group. For
example, to guarantee that 75% of bandwidth will be available for this diff­
class group, enter:
ProCurve(config-spomap-dcg)#bandwidth percent 75
You can guarantee a specific amount of the 10Gbps bandwidth (in Kbps). For
example, if you want to guarantee at least 2,500,000 kbps, enter
ProCurve(config-spomap-dcg)#bandwidth bandwidth 2500000
