FDDI PORT A/B TESTS
When the FDMMIM transmits or receives frames via the primary or
secondary FDDI network ring, the frames must pass through the
FDMMIM A or B ports. The FDDI A and B tests check the hardware
components that control communications through the FDMMIM A
and B ports. No signals are transmitted to the network dual ring.
FNB TEST
FNB is the Flexible Network Bus, the data pathway within the
MMAC hub. This test checks the FDMMIM hardware components
that handle communications with the FNB. No signals are actually
transmitted to the FNB.
FDDI TESTS
After a frame enters the FDMMIM Port A, Port B, or the FNB, it
enters the Media Access Control (MAC) circuitry. The FDDI tests (1,
2, 3, and Loopback) check the FDMMIM internal data paths.
ETHERNET PORT SELF TEST
This test checks the internal data paths used by a frame that enters
the FDMMIM through the Ethernet port. This test does not
transmit any signal onto the network.
HARDWARE FILTER TEST
The bridge filter functions are rooted in hardware components to
maximize bridge performance. The hardware filter test checks these
filtering components.
INLINE FILTER TEST
When the inline filter receives frames on the FDDI port that require
filtering, it uses the other FDMMIM filtering components to
accomplish the task. This test generates several frames to test the
filtering function of the hardware components.
