Hi, Guys,

 

Three infrastructures modes ( standalone SRX345, SRX345 HA active-standby, SRX345 HA active-active ) are tested ( with different Junos versions ). Two infrastructures get normal response of RTT results, except the HA active-standby mode, the issue is shown as below:

 


RPM configurations:
set services rpm probe WTT_Line_Test test HK-ISP_TEST probe-type icmp-ping
set services rpm probe WTT_Line_Test test HK-ISP_TEST target address 18.25.21.29
set services rpm probe WTT_Line_Test test HK-ISP_TEST probe-count 2
set services rpm probe WTT_Line_Test test HK-ISP_TEST probe-interval 5
set services rpm probe WTT_Line_Test test HK-ISP_TEST test-interval 5
set services rpm probe WTT_Line_Test test HK-ISP_TEST destination-interface reth1.110
set services rpm probe WTT_Line_Test test HK-ISP_TEST hardware-timestamp
set services rpm probe WTT_Line_Test test HK-ISP_TEST next-hop 18.25.21.29

 


The traceoption results ( normal ):

Dec 6 04:35:17 PING_TEST_COMPLETED: pingCtlOwnerIndex = WTT_Line_Test, pingCtlTestName = HK-ISP_TEST
Dec 6 04:35:17 RTM_CHANGE gencfg for probe WTT_Line_Test, test HK-ISP_TEST to state PASS

Dec 6 04:35:17 test_done: sent 2, test 810

Any reason the result of the comand " show service rpm history-result" can not show the RTT results ?

 

Thanks

Hi Ben,

 

I would try to narrow down the issue further.

- Try to ping the target and configure flow traceoptions to see if the return packet is reaching and getting dropped for any reason:

> ping 18.25.21.29 interface reth1.110

> for enabling flow traceoptions you can check this document:

Hope it helps!

Hi, Kinshukc

 

Thanks so much for your reply.

 

As shown from my results, with the RPM traceoption, it can show all got readings normally.

However, from the command "show service rpm history-result", it can not display the round trip time (RTT) value ( but showing "Time out" )..any reason ?

For my understanding, "show service rpm history-result" is just to calculate the rdiff values and to display the RTT value ?

 

Thanks
