Netvanta 7100 basic config help

Jump to solution

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.

Hi roxis13:

  1. no ip dhcp pool "<pool name>"
  2. What kind of ports do you mean?
    1. Switch ports
      1. interface switchport 0/12 (for example)
      2. shutdown (to disable)
      3. no shutdown (to enable)
    2. TCP/UDP ports
      1. The firewall will block all inbound traffic (sourced from the public) by default
      2. The firewall will allow all outbound traffic (source from the LAN) by default
      3. Maybe check out this document for starters on how to modify these default behaviors (to allow some traffic in or block some traffic heading out)
  3. The document just mentioned is great, but here's one about the firewall menu in the web GUI, and here's a video about port forwarding, which is the most common modification when configuring firewalls
  4. Suggestions
    1. You can normally prepend "no" to undo a particular command (such as no shutdown to revert a disabled interface into available state after you shut it down)
    2. It's a good idea to save your configs as you go.  You can copy running-config example-config-1.cfg, for example, to save to flash (non-volatile/permanent) memory.  Later, you can copy example-config-1.cfg startup-config (then reboot) to revert to the previous snapshot at next power-up.  Of course, the web GUI makes it easy to save your config and download a copy to your computer.  Here's a thread about doing the same using CLI (such as PuTTY).

Best,

CJ
