Connect 10gig ISE port on 1 Gig Switch port

[Security-enthusiast]

Hi All,

We have a SNS3615 which we are planning to setup in production and it has a 10gig interface. But currently, on our core switch 3750, there's no 10gig slot available, but we have 1gig slots. So will the ISE have any issues if we plug in a 10gig interface to a 1gig slot?

As per the Cisco Secure Network Server 3600 Series Appliance Hardware Installation Guide:

"The dual LAN ports can support 1 Gbps or 10 Gbps depending on the link partner capability."

Those are specifically the two c220m5 built in rj45 copper ports that are 1/10g capable. Not the 4x pcie mounted 1g ports above.
