  • Page 5: Introduction

    The Dell Force10 MXL 10/40Gb switch is the latest Dell switch with this feature. Up to six Dell Force10 MXL switches can be connected in a single stack using QSFP+ (40Gb) ports.

    Master role but instead take the next available role as Standy or Member. Stacking LAG When multiple links between stack members are used, the Dell Force10 MXL automatically bundles them into a single logical link, or LAG, providing higher stacking bandwidth and redundancy. The stacking LAG is established automatically without user configuration once all ports used in the LAG are set in stacking mode.

    Stacking Dell Force10 MXL 10/40G Switches Another way to completely wipe out all configurations and return to factory defaults is to erase the meta-data (NVRAM) and delete the startup configuration by following the instructions in Restoring factory defaults below. Restoring factory defaults Usually a standalone MXL can be set to factory defaults simply by deleting the startup configuration and reloading the switch (Step 2).

    Provisioning can be used to help configure a stack or a stand-alone system. With minimum effort, BMP can obtain IP address, running configuration and boot image information from a DHCP server. For more information regarding how to setup BMP, consult the Dell Force10 MXL User Guide.

    Stacking Dell Force10 MXL 10/40G Switches Combining split 10GbE SFP+ ports into a single 40GbE QSFP+ port The MXL 10/40GbE Switch supports splitting each 40GbE port on the base module or a 2-Port 40GbE QSFP+ expansion module into eight 10GbE SFP+ ports using a breakout cable. However, ports must be combined into single 40Gbe QSFP+ ports to operate in Stacking mode.

  • Page 15: Creating The Mxl Stack

    Connecting additional cables in parallel will increase the stacking bandwidth. Dell recommends that you connect the stack in a ring topology for resiliency and also that you use the same number of ports between peers in the stack.
  • Page 16 Stacking Dell Force10 MXL 10/40G Switches In this example, stack-groups 0 and 1 correspond to the base MXL interfaces 33 and 37. Stack-groups 4 and 5 correspond to the two 40G QSFP+ expansion module interfaces inserted in slot 1. Since stacking MXL switches does not use 10Gig Interfaces, there are no stack-groups associated with the SFP+ or 10GbaseT port that may be installed.
  • Page 17 Stacking Dell Force10 MXL 10/40G Switches Maximum stack-group per unit A maximum of 4 stack-groups per unit can be configured. In a ring topology, that would be 2 stack- groups in each direction, i.e 80Gbps stacking bandwidth. In a two unit stack, a maximum of 4 stack- groups between the two units (i.e 160Gbps stacking bandwidth) is allowed.

    Stacking Dell Force10 MXL 10/40G Switches Un-stacking (removing member units) Minimizing traffic flow interruptions is always the primary goal when removing member units from a stack. Four possible scenarios pertaining to unstacking or removing a member unit are: 1. Intentionally reducing the size of a ring topology stack 2.
