2026-06-02 16:42:07,263 - INFO - TEST DESCRIPTION :
Description:
check traffic configuring different tcp_mtu_probe vlaues on vm
MTU probing values: 0, 1, 2
0 - Disabled (default)
1 - Disabled by default, Enabled only when ICMP black hole detected
2 - Always enabled, using the initial MSS value of tcp_base_mss
system internally enables bit values for point 1&2
For test purpose,
Idea is to check traffic works fine on configuring values
Vm's across compute node
steps:
1. create 1 VN and launch 2 VMs in same compute node
2. client and server VMs in same compute node
3. configure tcp_mtu_probe to 0, 1, 2
4. send icmp traffic assert if ping fails
5. send tcp traffic assert if tcp traffic fails
Pass criteria:
1. If icmp/tcp traffic work fine configuring tcp_mtu_probe values
