QoS Policies
Quality of Service Guide 33
• In profile maps to the high slope.
• Out of profile maps to the low slope.
• Exceed profile maps to the exceed slope.
If the following SAP egress QoS policy is applied to SAP on an FP with the egress WRED
megapool enabled:
sap-egress 10 create
queue 1 create
wred-queue policy "slope1" mode pool-per-queue
slope-usage default
exit
exit
the details of both the megapool and queue pool usages can then be shown using this
command (detailed version):
*A:PE# show megapools 2 fp 1 wred service-id 1 detail
