Configuring QoS

Using Condition Groups in Policies

page 40-43

3 Attach the condition to a policy rule. (For more information about configuring rules, see 

.) In this example, action act4 has already been configured. For example:

-> policy rule my_rule condition cond3 action act4

4 Apply the configuration. See 

 for more information about 

this command.

-> qos apply

The next sections describe how to create groups in more detail.

Use network policy groups for policies based on IPv4 source or destination addresses. Note that IPv6 
addresses are not supported with network groups at this time. The policy condition will specify whether 
the network group is a source network group, destination network group, or multicast network group.

• Default switch group—Note that by default the switch contains a network group called switch that 

includes all IPv4 addresses configured for the switch itself. This network group may also be used in 
policy conditions. 

• ACLs—Typically network groups are used for Access Control Lists. For more information about 

ACLs, see 

To create a network policy group, use the policy network group command. Specify the name of the 
group and the IPv4 address(es) to be included in the group. Each IPv4 address should be separated by a 
space. A mask may also be specified for an address. If a mask is not specified, the address is assumed to 
be a host address.

Note. Network group configuration is not active until the qos apply command is entered.

In this example, a policy network group called netgroup2 is created with two IPv4 addresses. No mask is 
specified, so the IPv4 addresses are assumed to be host addresses.

-> policy network group netgroup2 10.10.5.1 10.10.5.2

In the next example, a policy network group called netgroup3 is created with two IPv4 addresses. The 
first address also specifies a mask.

-> policy network group netgroup3 173.21.4.39 mask 255.255.255.0 10.10.5.3

In this example, the 173.201.4.39 address is subnetted, so that any address in the subnet will be included 
in the network group. For the second address, 10.10.5.3, a mask is not specified; the address is assumed to 
be a host address. 

The network group may then be associated with a condition through the policy condition command. The 
network group must be specified as a source network group or destination network group. In this 
example, netgroup3 is configured for condition c4 as source network group:

-> policy condition c4 source network group netgroup3
