intra / inter network (conection) mirroring on viprion

when reading the Viprion configuration guide it says that F5 advises to use intra (within cluster) network mirroring and that this is mutually exclusive from inter network (between clusters) mirroring.

 

 

i can understand part of the logic for a Viprion cluster with 2+ active slots. but when using just 1 slot is inter not the only logical choice? assuming you have two Viprion clusters in active / standby setup. or is it wise to just keep it at intra for when the 2nd slot is used?

 

 

i hope that at some point both options will be possible, i feel currently it is an annoying choice to make.

 

 

BTW: does anyone know the tmsh command to switch between intra (Within Cluster) and inter (Between Clusters) network mirroring?

  • I'm curious as well.. unfortunately, it is my observation that VIPRION is not adequately supported like the rest of the BIG-IP line. This is especially true for v11 + VIPRION.
  • I have just implemented this on my Viprion pair. I am running 12.1.1 with HF2.

     

    The tmsh command to implement this is as follows: modify sys db statemirror.clustermirroring value between

     

    [the default value is within]

     

    Use the following command to display the current value: list sys db statemirror.clustermirroring

     

  • Piotr Lewandowski - Yes, the network mirroring option "Within Cluster" / "Between Clusters" applies to vCMP guests.

     

    Note that:

     

    • "Within Cluster" is irrelevant for vCMP guests running on a single blade.
    • "Between Clusters" is irrelevant for standalone vCMP guests.
  • Hello guys!

    I know this thread is old, but I'm leaving my findings here as a reference.

    I was able to double-check this thing on production environment. We had 2 2400 VIPRION chassis running vCMP. On the chassis, the sys db was configured with between:

    root@(NDCLPBIPPRD01)(cfg-sync Standalone)(/S1-green-P:Active)(/Common)(tmos) list sys db statemirror.clustermirroring
    sys db statemirror.clustermirroring {
        value "between"
    }
    

    But the vCMP was the default with within:

    root@(NDCLPBIPPRD-SAS01)(cfg-sync In Sync)(/S1-green-P:Active)(/Common)(tmos) list sys db statemirror.clustermirroring
    sys db statemirror.clustermirroring {
        value "within"
    }
    

    As expected, the connection mirroring was not happening between the vCMPs.

    root@(NDCLPBIPPRD-SAS02)(cfg-sync In Sync)(/S1-green-P:Standby)(/Common)(tmos) show sys connection type mirror
    Sys::Connections
    Total records returned: 0
    

    When I changed the sys db to mirror between and synced both vCMPs, everything worked like it supposed to.

    root@(NDCLPBIPPRD-SAS01)(cfg-sync In Sync)(/S1-green-P:Active)(/Common)(tmos) modify sys db statemirror.clustermirroring value between
    root@(NDCLPBIPPRD-SAS01)(cfg-sync In Sync)(/S1-green-P:Active)(/Common)(tmos)
    root@(NDCLPBIPPRD-SAS01)(cfg-sync Changes Pending)(/S1-green-P:Active)(/Common)(tmos)
    root@(NDCLPBIPPRD-SAS01)(cfg-sync Changes Pending)(/S1-green-P:Active)(/Common)(tmos) run cm config-sync to-group DG-SAS

    So... Long history short, sys db statemirror.clustermirroring is per chassis AND per vCMP.

    Hope this helps!

    Cheers! Rafael
