I would probably take a look at the 4500X (WS-C4500X-16), I don't know how much they run, but I would be willing to bet since we have 2 they are fairly cheap.

Yes, its more expensive the 4500X than the 3850.

4948 replacement is 4948e, that's what I meant apologies

TheGreatDoc

But what do you think about the C3850-12XS-S for Core and C3850-48T-E with C3850-NM-4-10G for internal routing?

My advice to you is think about scale. How fast the company is moving will dictate a lot of things like how many 1/10G ports you will need over time. I'm at a small company myself that expects very large growth over the next few years. So instead of providing one option I'm giving multiple with the pros/cons so management can decide if they want to spend the extra cash up front or know that we will need to replace some of these items later on that will cost more in the long run.

One thing you haven't mentioned is redundancy. If you buy a 12-port 10G switch and it fails, what's your recovery plan? Is waiting on TAC replacement good enough?

Ok, this is going crazy.

I just noticed that the 4500X-16SFP+ are cheaper than the 3850-XS-S.....

And I just noticed that hardware specs of 4500 are better than 3850....

Talk to your VAR or get access/training to the Cisco commerce workplace. I don't think you're doing it correctly (did you add all the necessary components like power supplies?)

A base WS-C4500X-F-16 SFP+ (IP BASE) with dual PSU  comes to 38,000AUD list price.
A base WS3850-12XS-S (IP BASE) with dual 750W PSU comes to 28,000AUD list price.

A fair difference.

Wow, I have waaaaaaaay differents prices than you said. Also, 3850-12XS-S have 350WAC PSU not 750. I dont like to say my prices, but I will tell you something:

I have the WS-3850-12XS-S with dual 350WAC PSU at ~12,000AUD (New, and our provider give us Lifetime warranty)

Since your list prices with mines have that big difference, I'm going to re-check with our providers they come with dual PSU.

Anyways, 3850-XS or 4500X-16SFP+?

There might be a big difference between list price and the price your provider gives you, if you have a existing relation its quite possible the price you got was with your default discounts included.

LIST PRICE as matgar says. nobody pays list price. ever.
 
Also, AUD is low. And Cisco's pricing for different regions is never the same. Finally, there may be a deal going on for your region for 4500Xs.

But lets take the AUD price at face value. Your seller probably gets 60% or even 70% discount. Thats 8400 @ 70% or 11200 @ 60%. Stick 10-20% margin on it and there's your 12000AUD price....

On the growth, as the company grows and the services flourish, your downtime maintenance windows  become increasingly minute.
like routerdork says provide multiple scenarios/solutions, i.e.  meets today's needs, meets needs in 3 years based on management planned growth, and meets needs in 5 years based on same, give management the options and let them make the decision.

last thing you want to to recommend a 15K piece of crap that will need to be upgraded next year. leave it to the ones running the company with your well provided knowledgeable lists of pro's and con's for each recommendation. That way you don't look like crap in management's eyes and they can't blame you for "their decision".

This. I second this notion. Or a N3K

Not the worst decision, it's better than 3850 or 2960
