Solaris Bandwidth Manager operates at the level of the physical interface (le0) and does not recognize logical interfaces (le0:1 and le0:2, for example). If your IP configuration includes logical interfaces, you can use the class hierarchy to subdivide network traffic according to the destination subnet, and then manage the traffic for each subnet separately. Figure 4-3 shows a configuration with two logical interfaces. The configuration file contains a definition for the le0 interface, and filter and class definitions for the subnet1 and subnet2 classes. For example:
filter subnet1 remote type subnet address 123.xxx.yyy.0 mask 255.255.255.0 filter subnet2 remote type subnet address 123.xxx.zzz.0 mask 255.255.255.0 interface le0 rate 263144 activate enabled class subnet1 parent root interface le0_in bandwidth 60 priority 3 max_bandwidth 100 filter subnet1 class subnet2 parent root interface le0_in bandwidth 40 priority 3 max_bandwidth 100 filter subnet2
