These are not IOS switches are they?
They run a modified version. Still learning about it.
Small things like vlan naming and switchport settings are different.
nonegotiate doesn't exist (or at least is buried)
spanning-tree settings are normal
annoying things like 64 character interface descriptions
rsa keygen isn't configurable. Must be locked to 2048
Most settings are still available and normal they just are slightly modified in how to access or the naming convention.
I would have preferred C9300-24UX...but those are 10x expensive; plus this is an office switch for bench use, a few idiosyncrasies will be aight.
