Configuring the Fabric Mode

Configuring the Fabric Mode


The actual forwarding capability of an LPU depends on the amount of bandwidth resources allocated to it by the SRU. An LPU can forward data at line speed only when it has sufficient bandwidth resources. An SRU provides limited bandwidth resources. In common fabric mode, the SRU allocates equal amounts of bandwidth resources to each LPU. The allocated bandwidth resources are sufficient for line-speed forwarding on most LPUs but cannot support line-speed forwarding on some high-performance LPUs. When these high-performance LPUs cannot realize line-speed forwarding, their forwarding capabilities are wasted.

A device supports extended fabric mode of the SRU. In this mode, LPUs in slot 6 and slot 7 can obtain more bandwidth resources to ensure line-speed forwarding.


Only S7712 and S9712 supportthis function.

In common fabric mode, the following LPUs cannot realize line-speed forwarding:
  • EH1D2X12SSA0/ET1D2X12SSA0 (S9712)
  • EH1D2L08QFC0/ET1D2L08QSC0 (S9712)
  • EH1D2X08SED4/EH1D2X08SED5 (S9712)
  • EH1D2X40SFC0 (S9712)
  • EH1D2X16SFC0/ET1D2X16SSC0 (S9712)
  • EH1D2X32SSC0/ET1D2X32SSC0 (S9712)
  • EH1D2C02FEE0/ET1D2C02FEE0 (S9712)
  • EH1D2X48SEC0/ET1D2X48SEC0 (S9712)
  • X2E series (S7712, S9712)
  • X2H series (S7712, S9712)
  • X2S series (S7712, S9712)
  • ES0D0X12SA00 (S7712)
  • ES1D2X16SFC0 (S7712)
  • ES1D2X40SFC0 (S7712)
  • ES1D2X32SSC0 (S7712)
  • ES1D2X08SED4 (S7712)
  • ES1D2C02FEE0 (S7712)

Pre-configuration Tasks

Before configuring the fabric mode on an S9712 switch, ensure that the switch is equipped with an EH1D2SRUDC00/EH1D2SRUDC01 main control unit.

Before configuring the fabric mode on an S7712 switch, ensure that the switch is equipped with an ES1D2SRUH000/ES1D2SRUH002 main control unit.


  1. (Optional) Run display fabric-mode configuration

    The fabric mode configuration is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run set fabric-mode turbo [ all | chassis chassis-id ]

    The extended fabric mode is configured.

    By default, the S7712 chassis with SWC02BAKG000 or SWC02BAKR000 backplane uses the common fabric mode, and other S7712 chassis models use the extended fabric mode. For the S9712, the common fabric mode is used by default.
