Description Use this command to verify the functional operation of the switch
components.
The spinsilk command may not be executed on an operational switch. You
must first disable the switch using the switchDisable command.
This command verifies the functional operation of the switch by
setting up the routing hardware such that frames received by port M
are retransmitted through port N. Likewise, frames received by port
N are retransmitted through port M. Each port M sends four frames
to its partner port N through an external fiber cable; thus exercising
all the switch components from the main board, to the GBIC, to the
fiber cable, to the GBIC, and back to the main board.
The cables can be connected to any port combination with the
condition that the cables and GBICs connected are of the same
technology. For example, a short wavelength GBIC port must be
connected to another short wavelength GBIC port through a short
wavelength cable; or a long wavelength port must be connected to
another long wavelength port.
Optimum test coverage occurs with
lb_mode 1, M-to-M loopback
plugs, and
splbMode disabled. In this case every port will exchange
frames with every other port and all of the ASIC-to -ASIC
connections are tested.
The frames are continuously transmitted and received in all ports in
parallel. The port LEDs flicker green rapidly while the test is running.
