Cisco Nexus 3K Layer 3 Connectivity Issue while using Optical SFP

[Kannan]

Dear All,

Am facing L3 reachability issue between N3k switched, even in same subnet. Also checked that VLAN is allowed under trunk port.

I can able to see the switch details as CDP neighbour.

We are using SVI, and found all the SVI and Interface protocol status is up/up. So to test I use a host to directly connect N3k with Optical SFP in access port, found failure on reachability, but while replacing with SFP ethernet module instead of SFP optical module reachability is okay.

Please help me to resolve this issue.

Thanks,

Kannan,
