  • 1.  support of Inline Active flow monitoring on MS-MIC with Junos 14.2 and Junos traffic vision V9 only

    Posted 11-07-2017 20:03

    Hi All,

    one of my customer having MX-480 & MX-960 and they want to use MS-MIC for inline active flow monitoring on each box. Junos version is 14.2 and they want to use Junos traffic vision V9 only.

    1. It seems from the below link that while using MS-MIC on Junos 13.2 and above , it supports inline active flow monitoring? is it true?

    https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/general/mic-mx-series-ms.html

    There is another link which is supporting the above statement.

    https://www.juniper.net/documentation/en_US/junos/topics/example/jflow-v9-configuring-on-ms-mic.html

    2. is there any difference between inline active flow monitoring and active flow monitoring?

    i will really apprecite your quick response on this query.

     

    Regards

    Badar

    Hi Badar,

     

     

    We can do flow monitoring using the below methods in junos:

     

    1. Inline active flow monitoring is implemented on the Packet Forwarding Engine on the FPC.

    2. Active flow monitoring is using MS-MIC/ Multiservice cards

     

    Inline Jflow is a feature which aims at supporting jflow on the pfe rather than on the services pic.

     

    Hope this helps

    Hi vvadivel,

    Thanks for clarifying the difference between Inline active flow and active flow. 

    One more question:

    1. Once we implement inline active flow monitoring which is in the PFE of the FPC, then why we use MS-MPC or MS-MIC for the collecting the flows. Below link clearly mentions that using inline active flow monitoring will save you to use services cards. 

     

    https://www.juniper.net/documentation/en_US/junos/topics/concept/inline-sampling-overview.html

    2. If a person want to use MS-MPC/MS-MIC only for collecting flows not for Natting or some other services, then is it adviseable to use MS-MPC/MS-MIC or or is it best option to use Inline active flow monitoring using PFE on FPC? 

    3. Is it possible to configure Active flow monitoring using MS-MIC-16G with Junos 14.2 with flow

    version 5 and flow version 8? 

     

    Looking forward for your kind reply. Thanks

    Regards

    Badar

    Ans. It depends on your requirement. Inline jflow can support max ~4 million flows whereas MS-MPC can upto ~30m.

     

    2. If a person want to use MS-MPC/MS-MIC only for collecting flows not for Natting or some other services, then is it adviseable to use MS-MPC/MS-MIC or or is it best option to use Inline active flow monitoring using PFE on FPC? 

    Ans. Again, it depends on the requirement. if you have huge amount of traffic to sample, then it's good to use service PIC. 

     

    3. Is it possible to configure Active flow monitoring using MS-MIC-16G with Junos 14.2 with flow

    version 5 and flow version 8? 

     

     Ans. Yes.

    Hi Kingsman,

    it is really helpful and thanks for your response. 

    One more thing that can i have some juniper documentation or some sample configurations which supports below text which was actually question-3 from my last post and you replied YES.  

    "Active flow monitoring using MS-MIC-16G with Junos 14.2 with flow

    version 5 and flow version 8"

     

    Last Questions: can we configure active flow montoring using MS-MIC with Junos 14.2?

     

    I will really apprecite your response. Thanks

    Regards

    Yes, we can configure the flow monitoring on 14.2 with ms-mic

    Hi Vadivelan,

     

    Thanks for the clarifications. 

    Finally, As you have replied that active flow monitoring can be configured on MS-MIC using Junos 14.2 with Version5 and Version8 but is it also supported on Junos Traffic Vision Version9 using same Junos 14.2 with MS-MIC? Thanks 🙂 

    Regards

    Hi Badar,

     

    Sorry for the confusion here. here's the updated information

     

    MS-MIC/MS-MPC doesn't support flow v5 and v8. 

    you can configure Junos Traffic Vision Version9 using Junos 14.2 with MS-MIC.
