RE: Why Should the Binary Math Method Be Used to Subnet [7:15311]
You may not always have a "tool" available to calculate for you. I've been in several customer meetings where I was required to come up with network diagrams, including subnet masks, ad hoc. If I had needed to have them wait til I could power up my laptop, then use a program to do the work, it would have looked unprofessional and reflected badly upon myself as an engineer and my company. The ability to calculate, in your head or on paper, subnet masks impresses clients, co-workers and bosses and keeps you sharp mentally.

I am not looking for a flame war, just education. The question I have is of what use is the binary math method of subnetting as compared to just using a program that does subnetting? If the point to the exercise is to produce a plan for subnetting that can then be entered into each device on the network or into a DHCP server setup, what else is achieved by doing this manually? It seems to me that the point is not the journey, but the arrival at the destination. Indeed arrival as quickly as possible, with the least source of error. As Cisco even says; "The purpose of this tool is to provide a way to calculate IP subnetting which is fast, easy, and error free. Doing such calculations manually is time consuming and susceptible to common mathematical mistakes, especially in conversions between binary and decimal numbers." So what is it I am not understanding?

RE: One interface-two IPs-& NAT? [7:15460]
Actually, if he's trying to do NAT with only one interface, it won't work.
You must have an inside (non-translated, usually private address range) and
an outside (translated, usually Internet-routable) interface. At least one
of each. What addresses you translate them into is irrelevant and can be
almost anything.

Subject:RE: One interface-two IPs-& NAT? [7:15460]
What you're suggesting can be done (although it seems like you should
research nat a little more fully to understand tactically what nat is...you
don't actually put two IP addresses on an interface when you do nat
translations).
But as I read your question, I think it's important to realize that the
ISP's router will always be your gateway to the internet whether you put
your own router onto your ethernet network or not. That means that the nat
translation *must* take place on the ISP router (specifically their
router's
ethernet interface. So, based on what I'm reading, you will need to
coordinate this with them regardless.

RE: 2500/2600 rack bracket screws??? [7:17461]
I have bought ones at Home Depot or Ace Hardware (can't remember which). I think they were like #6x3/8". Take one up there and let your fingers do the walking (that's what I had to do). They weren't an exact match (the ends were pointy, not flat, for one), but they fit and held. I think they were sheetmetal screws.

Very odd. I suspect bad simms or m/b. Could also be non-cisco approved mem. Some had a middle chip on them that seemed to do some sort of key/ID function.
