Hope you are doing well !
After checking the release notes on version 8095x + found that the Mac filter was modified to be Mac address access list for that reason does not allow to see the MAC filters on the GUI or create new Mac filters since this feature is no longer available.
This ACLs MACs would be only be visible through the CLI.
As you can see in the below picture you are going to see the MAC filter command was removed
This is the new way to preform ACLs MAC filters on 8095x + versions
If this feature is so important to you via GUI I would recommend the SPS8090mc version for you.
MAC filter is a configuration in sequence therefore, if you do not apply the deny any any option, it will allow any device to use this port (assuming that what you want is to configure that only 1 device is allowed per port)
This is a example I crate a MAC filter with a specific MAC address ( I did not add the deny any any ) and connect a PC ( with a different MAC ) to my switch and allow me ping ( sent data ) to the IP address as you can see '1'
once I applied the deny any any on the Switch '2' I say that it is not allowed that another device that is not in the filter (configured) can connect or have connectivity to my switch.
PC MAc 0050.56abab.d8
mac filter 1 permit 0051.56ab.abd8 ffff.ffff.ffff any
mac filter 2 deny any any
