Description
egress traffic, including
traffic contained on the
same I/O module port,
passes across the high-
speed back plane bus
through the Switch Fabric.
To guard against data bit
errors, the CPU software
continuously monitors the
data integrity between I/O
modules and CPU Switch
Fabric. If an anomaly/error
is detected, it could
propagate a data error into
the Switch Fabric, which
could compromise the
integrity of the egress
traffic.
The bfm refers to the
backplane forwarding
module. It is on every I/O
module and it connects the
I/O module to the backplane
of the switch. The octapids
and ASICs are the other half
of an I/O module.
Commonly the "bfm" will
have random packet tests
running between the
OCTAPID and the FADs,
located on the CPU. If the
FAD and OCTAPID packets
do not match, and this
happens on five
consecutive tests, an error
is reported, usually with a "
FAD misalignment reset
SWIP". The bfm runs a
random test between it and
the OCTAPIDS to show
where the failure is.
The Fabric Access Device
(FAD) is a module in the
SSF which sends packets to
the Backplane. ASIC on
SSF controls access to I/O
modules or backplane. The
Switch Processor (SWIP) is

Remedial Action
Reseat the module. If the error returns,
replace the module.
