connect 10G with 1G
Hi Experts,
I have a small NUTANIX setup for my EXCH solution.
In the past the 10G network was completly isolated, but now the supporter say, in NUTANIX it is easier to connect the 10G switch with my 1G switch.
The 10G switch is a CISCO NEXUS 3524
The 1G switch is now an old HP switch 4208
Is it possible to connect via SFP and SFP+?
Or do you have any other solution for me ?

if your 1G switch is not compatible to have 10GB module, it wont work.

Hi Predrag,
so I can put a SFP into my SFP+ slot on the 10G switch to connect to my 1G sfp switch ?
Is it correct ?

Yes.
You can check your device with SFP+ are SFPs supported, but from my experience typically SFPs are supported.

Does it mean, I need a tranceiver of one of this modules ?
GLC-SX-MM GLC-SX-MMD GLC-LH-SM GLC-LH-SMD GLC-T
These are the 1G BICs ?
GLC-SX-MM GLC-SX-MMD GLC-LH-SM GLC-LH-SMD GLC-T
These are the 1G BICs ?
Yes and yes.
GLC-SX-MMD and GLC-SX-MM are multimode, however Cisco does not support MM anymore (EOL) so you should have MMD in device in the case you need to contact TAC.
GLC-LH-SM and GLC-LH-SMD are singlemode - the same case as above, MM (EOL).
GLC-T - 1000BASE-T - RJ-45

Hi Predrag,
I have checked the Model GLC-T.
Am I right, this module I can put into my nexus switch with SFP+ .
Then I can connect a RJ45 to my 1 G switch right ?

Yes.
Have in mind it is recommended to use uplink ports for connection between switches.

Great.
my last question is, can I plug in this GBIC into my NEXUS 10G switch ?
Because they speak about SFP plug.

On the link that you gave is SFP (also called mini-GBIC).
GBIC is different connector type and you do not have GBICs on 35k Nexus.
Picture.

OK,
I have this module on stock from optcore: GLC-SX-MM-C
I think this is compatible with my NEXUS 3500 switch right ?

OK, I will order some from CISCO.
Another possibility I have.
I have a CISCO C4510 Switch with SUP and RJ45 Ports. This switch is in another room.
In my datacenter I have the NEXUS 3524 SFP+ switches.
Both rooms are connected with a backbone fiber patchpanel.
On both switches I have created a trunk but the link is not coming up.
I wonder if it possible over the backbone fiber patch panel ?
Another 1G connection over the fiber patch panel is working.
Do you have any ideas ?

maybe you can answer my previous question ?
I have ordered now these modules from CISCO:
GLC-T - 1000BASE-T - RJ-45
and
GLC-SX-MM

I wonder if it possible over the backbone fiber patch panel ?Yes, it should be OK with GLC-SX-MM if there is a multimode fiber and 1Gb GLC-SX-MM or GLC-SX-MMD SFP on the other end and device supports model of SFP that you are using (and of course Rx and Tx are set properly, distance is < 550 m).
Both sides must be 1Gb or 10Gb.
SFP+ slot support 1Gb SFPs, so you can use 1Gb SFPs to connect devices.
