Modifying a
QoS Class You can modify a QoS class in the Advanced Networking - QoS Classification <class
name> page.
Add New Rule Insert Rule At. To create a QoS rule for a QoS class, select start, end, or a rule number
from the drop-down list. Specify an ordered list of rules.
HP EFS WAN Accelerators evaluate rules in numerical order starting with rule 1. If the
conditions set in the rule match, then the rule is applied, and the system moves on to the
next packet. If the conditions set in the rule do not match, the system consults the next
rule. For example, if the conditions of rule 1 do not match, rule 2 is consulted. If rule 2
matches the conditions, it is applied, and no further rules are consulted.
Class Name. Select a class name from the drop-down list. If the rule matches, the
specified rule sends the packet to this class.
Source Subnet. Specify the IP address for the source network. Use the following format:
XXX.XXX.XXX.XXX/XX.
Port. Specify the port for the source subnet. The default value is All.
Destination Subnet. Specify the IP address for the destination network. Use the
following format: XXX.XXX.XXX.XXX/XX.
Port. Specify the port for the destination port. The default value is All.
