Quality of Service
ACL Metering andYou can define a profile for the aggregate traffic flowing through the HP 10GbE switch, by configuring a QoS meter (if desired), and assigning ACL Groups to ports. When you add ACL Groups to a port, make sure they are ordered correctly in terms of precedence.
For example, consider two ACL Groups, ACL Group 1 and ACL Group 2. Each contains three levels of precedence. If you add ACL Group 1 to a port, then add ACL Group 2 to the port, the port’s ACL filters contain a total of six precedence levels. ACL Group 1 has precedence over ACL Group 2.
Each port supports up to seven precedence levels.
Actions taken by an ACL are called
Metering
QoS metering provides different levels of service to data streams through

Using meters, you set a Committed Rate in Kb/s (1024 bits per second in each Kb/s). All traffic within this Committed Rate is
Meters keep the sorted packets within certain parameters. You can configure a meter on an ACL, and perform actions on metered traffic, such as packet
•Change the DSCP value of a packet, used to specify the service level traffic should receive.
•Change the 802.1p priority of a packet.
Viewing ACL statisticsACL statistics display how many packets hit (matched) each ACL. Up to 64 statistic counters can be displayed for each ACL Precedence Group. Use ACL statistics to check filter performance, and debug the ACL filters.
You must enable statistics (cfg/acl/acl x/stats ena) for each ACL that you want to monitor.
