No traffic between connected interface on Cisco 3105

Hello all,

I am configuring an SPF port (1/9) on Cisco 3105 as the LAN interface which connects to the Nexus 5000.

The IP on 3105 interface is 192.168.255.209/30 and the IP on Nexus interface is 192.168.255.210/30.

Both ports are up and online but I am unable to ping 210 from 3105 nor 209 from Nexus.

The show route output is:
C 192.168.255.208 255.255.255.252 is directly connected, lan
L 192.168.255.209 255.255.255.255 is directly connected, lan

Ping fails:
Sending 5, 100-byte ICMP Echos to 192.168.255.210, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)

I am not sure what is missing to make the config work. Can someone guide me in the right direction?

Could you please share relevant configuration from both ASA and switch?

Kind regards,

Milos

After the device reboot the interface came online
