hello this is my first time configuring a switch and router.
i just have a few questions on the right cmds to be using in the terminal while setting them up. i am using putty for my terminal.
1. how to remove a dhcp scope that is not needed?
2. how do i know what ports to shutdown? i was told to shutdown all unused ports. since this is a brand new basic setup and nothing with be pluged into this except in the end. i need to be able to plug a phone into the switch and then a laptop into that and be able to get onto the internet.
3. firewall setup ( i have been trying to look into this more but i cant seem to figure out where to start?
4.how to negate a config?
thank you so much for all who can help.
