Cisco Switches Requirements

[VCsupport17]

Hello Community,

Can you suggest switch models as per below requirement:

1. 12 port with 10G each port with 40G uplink Single Mode fiber - Access switch

2. 24 port with 10G each port with 40G uplink Single Mode fiber - Access switch

3. 48 port with 10G each port with 40G uplink Single Mode fiber - Access switch

4. 12 port with 1G each port with 10G uplink copper cable - Access switch

5. 24 port with 1G each port with 10G uplink copper cable - Access switch

6. 48 port with 1G each port with 10G uplink copper cable - Access switch

7. 12 port with 1G each port with 10G uplink Single Mode fiber - Access switch

8. 48 port with 10G each port with 40G uplink Single Mode fiber - Core switch

Hi

You don't mention whether this is a datacentre, branch or campus deployment or if switches need to be stacked/aggregated in some way.

I could quite happily tell you what switch models suit your requirements however have you tried Cisco switch selector? It's a simple quick way to look at your product options based on your requirements:

hello,

Thank you for your response. This is a campus deployment.

Switches will be link aggregated. I have attached the network diagram.

Hi

You could compare these Cisco switch models:

Cisco 3650

Cisco 3850

Hope it is useful

The core switch(es) based on your diagram seem to have a high concentration of 40G uplinks terminating on them. That combined with the need for 48 port 10G copper ports as well means I think you are looking at something like a 6506-E chassis at a minimum. You seem to have 2 core switches with similar capacity requirements so I'd strongly consider going for a supervisor that supports VSS (and the required 40gb/10gb modules of course)

For switches that require 40G uplinks and 10G copper on all ports, consider the  3850 XS switches with NM-40G uplinks (note the 48XS switch doesn't require an NM as it has built in 40G uplinks already)

For switches that require 10G uplinks and 1G on all ports, consider the 3650 TD switches

Hi Abache,

If i consider the 3850XS for 40G uplinks and 10G copper on all ports, do i need an SFP modules for the copper?

[abache]

Hi

Yes all the ports on the 3850XS use SFP+. You mentioned these will be copper and presently Cisco only offer Fibre Optic 10G SFPs or direct-attach Twinax 10G cables up to a distance of 10-15m (from memory). I'm not aware of a Cisco 10G copper SFP product. The reason for this I think is that RJ45  copper doesn't stand up as well compared to Twinax or Fibre Optic.

There are some non-Cisco 10G Cisco-Compatible Copper SFPs out there. But there is likely some caveats with using such a product: It will require high quality RJ45 cabling (e.g. Cat7), it will be limited to around 30m and RJ45 tends to suffer higher latency compared to Twinax or Optic cabling.

Based on the above, I'd suggest you try and use Twinax and or Fibre Optic for your 10G connectivity when and where you can.

Hi

Here you will find the switches to support 40G modules, not all the switches support 40G modules.

Talk to your Cisco AM/SE.  Your requirement is a prime position for the new Cisco 9300, 9400 and 9500.

These new switches have lower price points vs 3850.  The feature set, for example, starts at an IP Base "level" but price point of a 3850 LAN Base.
