Pinned topic Configure Vnic-groups on Stacked swtiches with LACP

‏2012-09-06T11:58:07Z |
Hi!

I tried to create Vnic-groups on our stacked Virtual Fabric 10Gb switches.

Usually you add the uplink-trunks to a "Trunk Group", but it doesn't accept adding a LACP-port in the Trunk Group.
And in the list of interfaces in the Vnic-Groups meny you can only choose one interface, and the LAG-interface is not in the list. I can only see the Physical interfaces and the Trunk Group.

Does anyone know how to do this?
Do I have to create serval Vnic-groups with the different interfaces in the LAG?

    Dear Fredrik,

      Hi and thans for the answer!

      That document is for the old firmware, this is from a new release:

      vNIC and switch stacking
      A stack is a group of BNT Virtual Fabric 10Gb Switch Modules that work
      together as a unified system and, therefore, is managed as a single entity.
      The network views the stack as a single switch entity, and the stack can be
      accessed and managed as a whole by using standard switch IP interfaces.
      After the stacking links are established, the number of ports that are available
      in a stack is equal to the total number of remaining ports of all the switches
      that are part of the stack. The numbers of available IP interfaces, VLANs,
      trunks, trunk links, and other switch attributes are not aggregated among the
      switches in a stack. The totals for the stack as a whole are the same as for
      any single switch that is configured in stand-alone mode.
      The BNT Virtual Fabric Switch supports stacking and Virtual Fabric Mode at
      the same time with the most recent firmware.

          Here is a releasenote from 2011:

          BNT Virtual Fabric 10Gb Switch Module Version 6.7.4.0 (Released September 2011)
          Changes since the 6.7.3.0 release
          Enhancements:
          Added the ability to use LACP trunks as vNIC-group uplinks.
          Added the ability for multiple vNIC groups to share the same uplink, which can be a port, static trunk, or LACP trunk.

          I think this is firmware 7.2.2

            Hi Fredrik,

            thanks for links.

            Did you enable vNIC/multichannel mode on your VFA cards?

            Hi all,

            I still can't find out how to setup an LACP trunk as the uplink for VNIC-group. The release note says:

            Added the ability to use LACP trunks as vNIC-group uplinks.

            That's exactly what I want to do. When I click in the web GUI on a particular vNIC-group I can select only regular EXT1-n port or a static Trunk group as the uplink.

            Can anyone tell me how to do it? Perhaps CLI?

            Thanks

              If you want to have a LACP uplink in a VNIC-Group you cannot have the switches stacked together, they must be standalone.
              And you have to configure this in the CLI, you'll choose the LACP admin-key as the uplink port.

              >> Configuration# virt/vmgroup/addkey
              Usage: lacpkey <adminkey>

                Sorry, the configuration example is for vmgroup, not vnic-group.
                Then I don't know how to configure LACP as vm-group uplink :(

    In the vnic vnicgroup configuration, add the LACP key number of the LACP aggregation you wish to use as the uplink;

    
    sw7(config)#vnic vnicgroup 1 sw7(vnic-group-config)#? vNIC group configuration mode enable      Enable the vNIC group exit        Exit vNIC group configuration mode failover    Enable uplink failover in the vNIC group key         Add the uplink LACP trunk to the vNIC group member      Add vNICs to the vNIC group no          Negate a command or set its defaults port        Add non-vNIC ports or the uplink port to the vNIC group trunk       Add the uplink trunk to the vNIC group vlan        Set vNIC group vlan sw7(vnic-group-config)#key 1001 ? <cr>

      And, in the GUI, in the drop-down list for "Uplink Port/Trunk/LACP trunk", the last item in the list is "Adminkey" which then allows you to add the LACP key.

      (my switch is running 7.4)
