actually I’ve got HP switches 2600 series and after writing “erase” and clicking “tab” button I see choices which I can make: erase config, flash, or start-up config.
But to erase configuration for only one port what about deleting this port (if it’s logical only) and write setting again?
And I don’t understand why you cannot try specific commands which you would like to erase with “no” commands: like
“no ip address”
Last method is most common.
Unfortunnatelly no L3 swtich is close to me.
