The S7900E Series Ethernet Switches are distributed devices supporting Intelligent Resilient 

Framework (IRF). Two S7900E series can be connected together to form a distributed IRF device. If an 

S7900E series is not in any IRF, it operates as a distributed device; if the S7900E series is in an IRF, it 

operates as a distributed IRF device. For introduction of IRF, refer to IRF Configuration in the System 

Volume.

Policy Routing Configuration Examples 

Policy routing is to make forwarding decisions based on user-defined policies. Different from the normal 

destination-based routing, policy routing can make routing decisions based on the source address and 

other criteria in addition to the destination IP address.  

The S7900E series switches implement policy routing through QoS policies. You can configure traffic 

classification and traffic redirecting action so that packets matching specific criteria will be forwarded 

along the specified path, thus to implement flexible routing.  

Policy routing takes precedence over destination-based routing. That is, if a packet meets the match 

criteria, policy routing applies; otherwise, destination-based routing applies.

For details about QoS policies, refer to QoS configuration in the QoS Volume.  

z 

SA boards do not support redirecting traffic to the next hop. Therefore, SA boards do not support 

QoS policy routing. 

 

Before configuring policy routing, you need to:  

z 

Configure a QoS policy, that is, to configure the match criteria and a redirecting action for policy 

routing.
