Description
Use this command to verify the intended functional operation of an ASIC pair (miniswitch) at the
maximum or selected speed by setting up the routing hardware so that frames received by port M are
retransmitted by way of port N. Likewise, frames received by port N are retransmitted by way of port M.
Each port M sends two frames to its partner, port N.
This test is run as a series of eight path tests. Each port on the ASIC pair is exchanging frames with one
port on the adjacent ASIC in the same miniswitch. At the end of a path test, the frames are captured and
the routing is changed so that each port exchanges frames with the next port on the adjacent ASIC of the
same miniswitch.
Unlike implementation of the spinSilk command, a port is only exchanging frames with one other port
at a time under the miniCycle command. Just like with spinSilk, all ports are active and exchanging
frames simultaneously with miniCycle.
The path number being tested determines the partner port N for each port M (bold and italicized in the
following example):
path 0: 0-8, 1-9, 2-10, 3-11, 4-12, 5-13, 6-14, 7-15
path 1: 7-8, 0-9, 1-10, 2-11, 3-12, 4-13, 5-14, 6-15
path 2: 6-8, 7-9, 0-10, 1-11, 2-12, 3-13, 4-14, 5-15
path 3: 5-8, 6-9, 7-10, 0-11, 1-12, 2-13, 3-14, 4-15
path 4: 4-8, 5-9, 6-10, 7-11, 0-12, 1-13, 2-14, 3-15
path 5: 3-8, 4-9, 5-10, 6-11, 7-12, 0-13, 1-14, 2-15
path 6: 2-8, 3-9, 4-10, 5-11, 6-12, 7-13, 0-14, 1-15
path 7: 1-8, 2-9, 3-10, 4-11, 5-12, 6-13, 7-14, 0-15
NOTE: The port numbers are relative to the ASIC pair. This test does not route frames from one
ASIC-pair to another.
Ports cabled to other ports fail if port loopback mode is selected, and the port must have media and
loopback plugs installed. For best coverage, you should use self-loopback plugs and port loopback mode
(-lb_mode 1), as each port's external connectivity will be tested.
The frames are continuously transmitted and received in all ports in parallel. The port LEDs flicker green
rapidly while the test runs.
The path test method is as follows:
1. Clear port statistics and error counters.
2. Enable ports for specified self-loopback mode.
