There are four standard utilities, delivered either as part of the Solaris environment or in conjunction with the driver for the high-speed serial interface (hsi), that are used to test the serial devices used for synchronous links:
syncloop(1M) and syncstat(1M)
These utilities test the onboard serial interfaces (zsh0 and zsh1)
hsi_loop(1M) and hsi_stat(1M)
These utilities test the high speed serial interfaces (hihn)
Do not run syncloop or hsi_loop on a interfaces that are in use.Interfaces are in loopback mode while the tests are running, and cannot communicate with remote hosts.
There are four test options associated with syncloop and hsi_loop. Table 6-1 lists the equipment you require to run the different the test options.
