cli8895 is a command-line utility that can be used to interrogate the management lan/oobfo switch on the ACM5504-5.
From a command line run:
And you should see
Switch SPI read selftest OK.
Switch SPI write/read selftest OK.
KSZ8895 CLI Function version 1.0.2 .
If you get information about a self test failing, just run it again. We get occasional bad values on reads via the MII bus that can cause the self test to fail.
From the => prompt in cli8895 you can run "help" to see the list of available commands.
Of particular interest are:
showmib - shows packet received/transmitted/dropped etc counts per port
macdyn - shows the learned dynamic MAC address table of the switch
You can also use cli8895 to change the switch settings, but without making corresponding changes to the ACM5504's configuration system and startup scripts, any changes will be lost on reboot.
