  • 1.  Dual fabric links on SRX5800

    Posted 02-11-2016 10:25

    Hello,

     

           I am new to the Juniper line of products and I was wondering if you can create aggregated fabric link (2 interface on the primary chassis and 2 on the backup chassis). I did set up the fabric link configured using the commands below and it is up.

    set interfaces fab0 fabric-options member-interfaces et-7/2/0

    set interfaces fab1 fabric-options member-interfaces et-19/2/0

           The fab link is up but I would like have a bigger pipe for the data connection between the clustered firewalls. So instead of having a 40gig pipe btwn chassis's, I would like to have a 80gig pipe. Is this possible with some type of LAG? I am running software version 12.1X46-D25.7 on each chassis. Thank you!

     

    Regards,

    Hi TDNY,

     

    The fab interface is itself a form of Link Aggregation ( if you do a > show interfaces terse | match fab you'll see that the interface type is of type aenet ); but it can only support two member interfaces per node.

     

    Btw, the configuration you shared only shows the configuration of one FAB link between the two nodes ( one member interface ).

    Hello Hisham,

     

           Thanks for the response. After reading the Juniper SRX series book by O'reilly online, you are correct it is (fab link) a form of a aggregated link. Yes you are corect is that I have one interface per node as fab link. So what I did was I deleted fab0 and fab1, then defined each interface for fab0 and fab1. Now when I run the command "show chassis cluster data-plane interfaces" it shows:

     

    fab0:

     

         Name                                                  Status

                                                                    (Physical/Monitored)

         et-7/0/0                                               Up      /  Up

         et-8/0/0                                               Up      /  Up

    fab1:

     

         Name                                                  Status

                                                                    (Physical/Monitored)

         et-19/0/0                                             Up      /  Up

         et-20/0/0                                             Up      /  Up

     

    Both interfaces on each node up and operational. Thanks.

     

    Regards,

    Yes, Good Work !

     

    Congrats ! Now you have dual fabric redundant links working !
