HP Procurve 2512/2524 protected port, source port filter or similar?
Solution 1:
In the 2524 and 2512 it is called "port-isolaton". It can be found in release notes matching your firmware. Weird thing is that I installed the F.05.77 but latest on official list is F.05.72

steps:
- Enable port-isolation
- After this all ports are marked as Uplink
- Mark all ports that are not Uplink as Public, Private, Local, Group1, or Group2
