Symptoms


An MX2-10G card has been set to STC-EL47 profile successfully, however when running Enhanced L47 test it will eventually failed to start showing an error message saying:

Failed to start test
timeout of 300000ms exceeded

After that, the MX2 module gets into a faulty state, and the ports you were using for the test remains "Reserved" by you forever, there is no way to take the ports from that sate, if you try to force the user off, the GUI will get stuck in 50%.

If you kill the GUI when that 50% stuck issue, the ports sometimes becomes "unavailable" and after some time they will show again "Reserved by:____".

The only way to recover the module is either rebooting it or rebooting the whole chassis.

We have tried an MX2-1G and is working fine, same with an FX2-10G-S8. Them both are working just fine.

It looks like the BLL gets stuck in:
 
fmwk.bll.core.equip - Received error response: seq 1251, msgr 10.108.8.20 test module 8 port group 2, req Enhancedl47_1.EnhancedL47RequestStateNotification, code 2, faultMsg failed to find message set Enhancedl47_1
Still waiting for msg(Enhancedl47_1.ConfigureEnhancedL47) seq(1250) msgr(port //10.108.8.20/8/1) response after 5 sec

 

Environment

 
  • STC 5.11
  • STC-EL47 profile
  • MX2-10G-S8
