Spirent TestCenter: Enhanced L4-7 not working on Spirent TestCenter Virtual - Test has failed. Please check settings and try again.
Objective/Summary
How to make Enhanced L4-7 to work using STCv (Spirent TestCenter virtual)
Environment/Versions
You may face this particular issue when STC L2-L3 traffic is working fine, but EL4-7 test is not starting, once test is failed then STC GUI is not letting you to create/modify the EL4-7 test again because it looks like EL4-7 test is not stopping as we can see in Log Window
Test has failed. Please check settings and try again
Procedure
Make sure the VM's meets minimum requirements.
Check the following KB as reference:
KNI16042
- Spirent TestCenter: Enhanced L4-7 clicking Apply hangs the GUI when using virtual ports.
You can run Enhanced L4-7 on up 2 STCv ports, however there is a STCv limitation in which you can NOT get client and server on the same port group, a single STCv instance has all ports on the same port group, hence you can NOT run a EL4-7 in b2b using a single STCv instance (VM)
Clarifying a bit, 2 ports from the same VM can be used to run EL4-7 as soon as those 2 ports are either just client or server (not a combination of both)
ALLOWED:
NOT ALLOWED:
Using a single ports from
two
VMs (one as a server, and the other as a Client - same as the example above under "ALLOWED" section ), EL4-7 works fine
Tested in b2b using 10G and 5.18.0296
