Validates that the routing of packets between sub-ports are not affected by the removal of other sub ports.
Test steps:
Test steps:
1.) Setup configuration of sub-ports on the DUT.
2.) Setup configuration of sub-ports on the PTF.
3.) Add one of the sub-ports to namespace on the PTF.
4.) Setup static routes between sub-port and sub-port in namespace on the PTF
5.) Create packet (TCP, UDP or ICMP).
6.) Remove some other sub ports
7.) Send packet from sub-port to sub-port in namespace on the PTF.
8.) Verify that sub-port gets received packet on the PTF.
9.) Remove static routes from PTF
10.) Remove namespaces from PTF
11.) Clear configuration of sub-ports on the DUT.
12.) Clear configuration of sub-ports on the PTF.
Note:
Test verifies two cases of routing between sub-ports:
1.) Routing between sub-ports on the same port
2.) Routing between sub-ports on the different ports
Pass Criteria: PTF port gets packets from port in namespace on the PTF.
