    Hello all,

     

    I just enabled virtual-chassis between my two qfx5100-48s-6q swithces and I am seeing some odd behavior. I am not able to see the backup linecard ports with the command "show interface terse" but I am able to set additional interfaces and then commit succesfully. As a test, I added interfaces xe-1/0/25 , xe-2/0/25 and xe-3/0/25 and commited succesfully. Is that expected behavior when I only have two switches? Furthemore, the new interfaces I created do not shop up with the interface terse command but they do appear in the running config.

     

    {master:0}[edit]
    atetu@emp-cle.core-01.qfx5100# set interfaces xe-2/0/25 description TEST


    {master:0}[edit]
    atetu@emp-cle.core-01.qfx5100# set interfaces xe-3/0/25 description TEST

     

    {master:0}[edit]
    atetu@emp-cle.core-01.qfx5100# commit
    fpc0:
    configuration check succeeds
    fpc1:
    commit complete
    fpc0:
    commit complete

     

    I attached a file with the output from show virtual-chassis / vc-port statistics extensive and the output looks correct.

     

    Thanks in advance,

    -AT

    Hi Adrian,

     

    Looking at the outputs attached I see that you have 2 members on the stack, however you are configuring following interfaces,

    {master:0}[edit]
    atetu@emp-cle.core-01.qfx5100# set interfaces xe-2/0/25 description TEST
    {master:0}[edit]
    atetu@emp-cle.core-01.qfx5100# set interfaces xe-3/0/25 description TEST

    These will not show because the numbering used is based on members 2 and 3 that don't exist, the validation of the configuraiton will be depending on the version you are using, maybe a code will allow you to commit and other code will not.

    Can you plesa share the output of >show chassis hardware to confirm what interfaces are configurable

     

    Regards,

    Jeffry Rivera

    Hi Jeffry,

     

    Thanks for your reply! I will get the additional vc output in the morning but I enabled ports xe-2/0/25 & xe-3/0/25 just to see if it works. Your reply answered why the unit accepted the config and commit. I tried doing "set interface xe-?" and xe-1/0/x was not an option, just xe-0/0/x. After configuring port  xe-1/0/25,  the output appears in show config but not in interface terse.

     

    et-0/0/48 {
    unit 0 {
    family inet;
    }
    }
    et-0/0/50 {
    description "VC-PORT 1 of 2";
    }
    et-0/0/51 {
    description "VC-PORT 2 of 2";
    }
    xe-1/0/25 {
    unit 0 {
    family inet;
    }

     

    Thanks,

    -AT

    Hi AdrianT04,

     

     

    Greetings, regarding the non-existent interfaces showing up in the configuration file, is expected, you have a range from 0 to 9 FPC's since you are using a standard VC set up, if you go above that you will see an error message like this : error: fpc value outside range, what is not ok is not being able to see xe-1/0/25 using the show interfaces terse  

     

    Can you share the output from the following commands:

    >show chassis hardware
    >show configuration chassis

    Do you have an optic inserted or a DAC cable in port xe-1/0/25? if no, please insert one, if yes do you see any lights?

    Hi LilDexx,

     

    Thanks for your reply! I do not have remote access to the unit yet but I will get the additional vc output in the morning. I enabled xe-1/0/25 just to see if it works. I am using two DAC cables in ports 50 and 51 on both units. I tried doing "set interface xe-?" and xe-1/0/x was not an option, just xe-0/0/x.

     

    Thanks,

    Hi LilDexx,

     

    I attached the show chassis hardware and config output. I plugged a fiber module into port xe-1/0/25 and port shows up now in the interface terse output. I connected another fiber module into port xe-1/0/29 without any sort of configuration and that port shows up as well now. Can you please confirm if everything looks alright? 

     

    --terse snippet--

    ge-0/0/47.0 up up inet 10.10.100.51/24
    pfe-1/0/0 up up
    pfe-1/0/0.16383 up up inet
    inet6
    pfh-1/0/0 up up
    pfh-1/0/0.16383 up up inet
    xe-1/0/25 up down
    xe-1/0/25.0 up down inet
    xe-1/0/29 up down
    xe-1/0/29.16386 up down

     

    Thanks,

    Hey AdrianT04,

     

    Glad to hear that, it means that the chassisd was able to recognize the interface as part as the hardware inventory, nevertheless, I am not seeing the optic in the show chassis hardware, can you do a physical loop with those 2 ports and check the following directly from the PFE :

     

     

    >start shell pfe network fpc1
    PFEM0(vty)#show sfp list ---->you should see the optics listed 
    PFEM0(vty)#show sfp <Index> info

     

    From CLI


    show interfaces diagnostics optics xe-1/0/25
    show interfaces diagnostics optics xe-1/0/29

    Hi LilDexx,

     

    I think I copied the show chassis hardware output before I inserted the SFPs. I believe everthing looks good at the moment.

    AdrianT04,

     

    Ohh... Great! that makes sense now, so now with all authority and doubtlessly I can confirm that everything is working like a charm.

    You have my blessing Sir, enjoy Junos!
