Connection from XL710 for 40GbE QSFP+ to N3000 XXV710 for 25GbE SFP28



We were trying to connect XL710 for 40GbE QSFP+ to N3000 XXV710 for 25GbE QSFP28(direct connection) but we are seeing that link itself is not coming up.

Is this connection not supported or is there any configuration required to make this work?

Please LMK if any additional info is required
