Mixed 10GB/1GB upload switch

 

Good Morning everybody.

I need help finding a cisco product.

Currently I have a network with all 10/100 access switch (2950, 2960) with gigabit uplinks to a 2x6500(vss)

I have to choose the new access switches and I want them 10GB uplink capable.

I don't really need all that throughput now, but surely I'm not going to change all the access switches again just the day after ;)

Also, I don't have a 10GB ports line card on the 6500s, so I want the access switches 10GB capable, but I want to connect them at 1GB for now.

Is it (tecnically) possible to have a switch that can run both 1GB and 10GB fiber uplink ports?

Ideally, could a 10GB capable switch run a 1GB SFP optic in an SFP+ port?

If so, could you kindly help me suggesting the right product?

Sorry if I'm not not the right forum.

Thank you.
Regards.

Hi,You can get the 3850

Hi,

You can get the 3850 series with this card (C3850-NM-2-10G) for your uplinks.  You can use 2 10Gig and 2 1Gig.  So, for now you can use the 1Gig ports until you are ready to go to 10Gig.  At that time you just need to purchase SFP+ and you are ready to go to 10Gig.

See table-2 and 3 in this link;

Hi, You can use 3650 series

Hi,

 

You can use 3650 series switches. Please refere table2 in below link

 

The SFP+ interface supports both 10 Gigabit Ethernet and Gigabit Ethernet ports. Refer to Table 1 for a description of the basic switch models and the corresponding uplink ports. Refer to Table 2 for a description of the various uplink port interface options.

Besides the 3K switches, if you've been happy with your 2960s, the later variants, e.g. 2960-S and 2960-X, have modules that support SFP+.

Great Joseph!Since Akash gave

Great Joseph!
Since Akash gave me the great information "The SFP+ interface supports both 10 Gigabit Ethernet and Gigabit Ethernet ports", I was just asking about the "2960S-48TD-L".
Can you please kindly confirm my understanding?
Do you mean I can run safely a 1GB SFP into the SFP+ port of the 2960 switch and then, in the future, simply replace that interface with a 10GB one?
If so, this is a great news.

Since that are all access switches, I need only few features (Simple QoS, dot1x, BPDUguard and some more...) and have to buy a lot of them.
So 3x series are surely great, but I'd prefer to go with a simpler (and cheaper ;)) model for this task.

Many Many thanks you all for your precious help

It depends on the model.  On 2960s yes that is possible see table-1 in this link:

http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-series-switches/product_data_sheet0900aecd80322c0c.html

 

On 2960-X and XR depends on the model but they do not come with ports that support 1 and 10gi.  It is either or and not both like the 2960s.

 

see table-1 and 2 in this link:
