Using Solaris Bandwidth Manager, you can classify traffic based on the source or destination IP address of an individual machine. If you want to classify all of the traffic from a given network or group of networks, a convenient way to do this is to create a subnet group. To create a subnet group for the Bonn site:
Display the Host/Subnet Groups configuration window by clicking the Host/Subnet Groups tab.
Click the new icon to create a new group.
Allocate a name to the group, by changing the default name new.
Specify that the group type is Subnet.
Specify the list of subnets that belong to the Bonn site. To do this, click the top left of the Addresses pane -- this creates an editable field where you can type an address. After entering an address, click Apply, this records the address you just entered and makes the line below writable for your next entry. Specify subnet addresses in standard IP dotted notation.
Specify the subnet mask for these addresses.
Click Apply then choose Save from the File menu to save your changes.
You could also use a host group for the same purpose, but you would have to enter the IP address of each host at the Bonn site separately.
