Quality of Service
87
The basic HP 10GbE switch QoS model works as follows:
• Classify traffic:
○ Read 802.1p Priority.
○ Match ACL filter parameters.
• Meter traffic:
○ Define bandwidth and burst parameters.
○ Select actions to perform on in-profile and out-of-profile traffic.
• Perform actions:
○ Drop packets.
○ Pass packets.
○ Mark DSCP or 802.1p Priority.
○ Set COS queue (with or without re-marking).
• Queue and schedule traffic:
○ Place packets in a COS queue (configurable as either 2 or 8 queues).
○ Schedule transmission based on the COS queue weight.
Using ACL filters
Access Control Lists are filters that allow you to classify and segment traffic, so you can provide different
levels of service to different traffic types. Each filter defines the conditions that must match for inclusion in
the filter, and also the actions that are performed when a match is made.
Summary of packet classifiers
The HP 10GbE switch allows you to classify packets based on various parameters, such as:
• Ethernet
○ Source MAC address/mask
○ Destination MAC address/mask
○ VLAN number/mask
○ Ethernet type
○ Ethernet Priority, which is the IEEE 802.1p Priority
• IPv4
○ Source IP address/mask
○ Destination IP address/mask
○ Type of Service value
○ IP protocol number: The protocol number or name as shown in the following table:
