Understanding How the Switch Fabric Module Works

Switch Fabric Module Overview
The Switch Fabric Module creates a dedicated connection between fabric-enabled modules and provides
uninterrupted transmission of frames between these modules. In addition to the direct connection
between fabric-enabled modules provided by the Switch Fabric Module, fabric-enabled modules also
have a direct connection to the 32-Gbps forwarding bus.
The Switch Fabric Module does not have a console. A two-line LCD display on the front panel shows
fabric utilization, software revision, and basic system information.
Switch Fabric Module Slots
With a 13-slot chassis, install the Switch Fabric Modules in either slot 7 or 8.
In a 13-slot chassis, only slots 9 through 13 support dual switch fabric interface switching modules (for
Note
example, WS-X6816-GBIC).
With all other chassis, install the Switch Fabric Modules in either slot 5 or 6.
Switch Fabric Redundancy
The Switch Fabric Module first installed functions as the primary module. For redundancy, you can
install a redundant Switch Fabric Module. When two Switch Fabric Modules are installed at the same
time, the module in the upper slot functions as the primary module, and the one in the lower slot
functions as the backup. If you reset the module installed in the upper slot, the one in the lower slot
becomes active.
No configuration is required for Switch Fabric Module redundancy. The module in the upper slot
functions as the primary module and a redundant Switch Fabric Module in the lower slot automatically
takes over if the primary module fails.
Forwarding Decisions for Layer 3-Switched Traffic
Either a PFC2 or a Distributed Feature Card (DFC) makes the forwarding decision for Layer 3-switched
traffic as follows:
