Traffic Flow From the WAN

Traffic from the WAN is forwarded to the LAN via ipqos3 and ipqos2.

• ipqos3. Packets are not classified and scheduled in the following circumstances:

  • if ipqos3 is not configured for regulating incoming traffic

  • the multicast parameter is set to direct

  • the packet is not an IP packet and non-IP mode is set to direct

• ipqos2. This module checks the destination IP address. If the packet is addressed to the host running Solaris Bandwidth Manager, it is sent up the IP stack, via ipqos1. Otherwise it is forwarded to its destination.

Only ipqos3 can be configured via the configuration file so any reference to the interface in this file must be the WAN interface. Configure the network device option in the configuration file to reference the LAN interface in one of the following ways:

• by editing the network keyword in the interface section of the configuration file

• using the Configuration Interface window of batool.
