ilbstress Performs a stress test using the internal loopback at the PHY or framer
interface. Packets are generated by the MPX and sent out to the port and
returned through an internal loopback within the PHY or framer. The MPX
verifies the packets on a bit by bit basis. See the description for stress test
on page 36-8. If Ethernet type switch is tested, this test requires the
desx.img file to be in the flash memory.
mamcam Tests the Mammoth CAM. Tests the Mammoth CAM control logic, CAM
access, and the data line and buffers.
mammem Tests the Mammoth registers and memory. Includes testing the Mammoth
control logic, registers, internal memory, internal cache, external SDRAM,
SRAM, and data/address lines.
mloopmac Performs a port test using the internal loopback within the Mammoth MAC
chip. Packet are generated by the MPX and sent out to the port and
returned through an internal loopback within the Mammoth MAC chip. The
MPX verifies the packets on a bit by bit basis.
morreg Tests the Moriah registers. Test the Moriah control logic, registers, and
data/address lines.
mvbus Tests the mammoth VBUS circuitry. Frames are generated within the
Mammoth buffer system, sent out the VBUS, and then received on various
Mammoth queues. Data integrity is verified.
pcam Tests the HRE-X Pseudo CAM. Tests the HRE-X Pseudo CAM control logic,
CAM access, and the data line and buffers.
port Functional testing of physical ports with a burst of data packets generated
by the MPX. Packets are generated by the MPX, sent out the physical port,
looped back through external cables or wrap plugs, and returned to the
MPX. The returned packets are verified bit by bit by the MPX. The port test
requires the use of external cables or wrap plugs. The system will provide
user with instructions for setting up external cables or wrap plugs for port
test and prompts the user for input upon completion of setup. This test can
be bypassed if cables are not available. For more information on port tests,
see Port Tests on page 36-9. For information on cables required for the port
test, see Omni Switch/Router Port Test Wrap Cable/Plug Requirements on
page 36-10 for the Omni Switch/Router.
♦ Important Note ♦
For VSD and VSA submodules, the port test requires no
outside cabling. It is a combination of multiple static
tests for the submodule, rather than a traffic test.
