Q:

I find that ports 51&52 on the switch are not displayed, why, is it faulty?

by M***h on 01/08/2022

A:

This is a normal phenomenon. Ports 51 and 52 disappear because the switches are stacked. After configuring stacking, ports 51 and 52 disappear. The ports will recover when you delete the stack command: \"no stacking enable 1 reboot\" and restart the switch.

What I've found is that the default settings on these switches are pretty much right where most users need to be. For example these support STP, RSTP, and MSTP. By default, they're all set to MSTP and it just works.
