Test Case: OpenFlow Switch Forwarding Test • Select the flow range again and see if switch starts forwarding traffic for that MAC/VLAN again. Conclusions This test case can be used to verify: • Switch installs correct flow entries in its flow table as pushed by the controller. • It makes packet forwarding decision as per the rule set by the controller. • It complies to one or more action set by the controller. Test Variables The following variables can be used to verify the behavior of an OpenFlow Switch. 1. L3 Forwarding Test Set the matching criteria on L3 header field such as Source IP, Destination IP and DSCP value 2. Use multiple Actions PN 915-2635-01 Rev A December 2012 41
Test Case: OpenFlow Switch Forwarding Test Apply multiple actions for each Flow range. Use one of the following actions along with Output and verify that switch correctly performs multiple actions on the packets. Set VLAN ID Strip VLAN Header Set Ethernet Src/Dst. Set IP DSCP Set IPv4 Src/Dst. Set Transport Src/Dst. Add or Change VLAN ID for matching flow Strip the VLAN header from the matching flow Change source/destination MAC for matching flow Change DSCP value for matching flow Change IP address for matching flow Change TCP/UDP port PN 915-2635-01 Rev A December 2012 42
