2960x vs 3850

[emmanuel.shoroma]

Hi,

I am deciding which switch to by to replace some of our old switches. Looking for some direct comparison between 2960x and the new 3850 (In exception of the Wireless controller and stack power).

looking for one to one comparison on PoE, performance, security, ios features, etc. the switches will be used for Layer access. no need for advanced routing.

Any idea of price different in percentage?

Need to use this for user access layer that connects directly to 6500 which is also planned to upgraded soon for 10G uplinks.

Regards,

I see no reason why not going with 2960X for access...for sure it's cheaper than 3850 one...

HTH,

I think 3850 should compare with 3750X series. 3650 is  the other series of switches if you are looking for similar to 3560/2960 as it is cheaper than 3850.

Technically I would prefer 3650 even if you are not using WLC functionality today (it gives flexibility where you can use them in future). Here is the 3650 switch information

Here is the 3850 series switch information

Pricing information you could check with your Cisco AM (I know there is no price differce between 3850 compare to 3750x, hope it is the case with 3650 & 3560x)

I am looking at doing the something similar, replacing older 2950s with new 2960x stacks. My question though is around the SFP/SFP+ ports. I know SFP can do 1G and SFP+ is for 10G but I am seeing conflicting information on if I can use a 1G SFP interface in a SFP+ port? In some places I see specs such as 4x1G SFP / 2x10G SFP+ foer a switch and then in a seperate place see that it is one or the other and not both. I have 1G backbone today but my new core supports 10G. The thought was to install new stack as 1G then upgrade to 10G once infrastructure needs are addressed. I also am trying to finalize if I need to replace fiber or need special SFPs since I have MM fiber between my IDF closets and the core today to go to 10G.

Today I am using a 3560G as a distribution switch with 3 to 7 2950s attached. I figure to colapse and have a simple stack of 2960x if I can work out the details. This would apply to 7 different IDF closets I have here in my building.

Hi Brent

My question though is around the SFP/SFP+ ports. I know SFP can do 1G and SFP+ is for 10G but I am seeing conflicting information on if I can use a 1G SFP interface in a SFP+ port? In some places I see specs such as 4x1G SFP / 2x10G SFP+ foer a switch and then in a seperate place see that it is one or the other and not both.

Most of switch network modules you can use 1G SFP in SFP+ ports. So If you have 4 port SFP/SFP+ uplink module you can use 4x1G SFP or  2x10G SFP+ (in certain cases like 3850 48 port switches, you can use this for 4x10G SFP+ as well) All depend on switch specs & read the data sheet as it listed all capabilities.

Here is some reference link for 3750 series switches uplink modules
