I have the following topology:
Default Gateway1 <--> SWITCH1 <--> [ NIC2 - (Windows 10 PC) - NIC1 ] <--> SWITCH2 <--> Default Gateway2 --> Internet
NIC1 is DHCP configured, and connects to the internet successfully.
NIC2 has a static IP address/subnet mask/default gateway (They are correct as I tested them on another machine) but I can't ping its IP from switch1, even though they are directly connected.
I'm trying to isolate the issue to find if it's from the switch or PC, I can ping default gateway1 from switch1.
For NIC2, Wireshark shows that ARP can't resolve the MAC address for default gateway1, although this interface receives CDP/VTP Packets from switch1.
Is this a case of windows preferring to use the first interface and "implicitly" disabling the other one? Or do I need a specific configuration under the interface on switch1?
The interface configuration (authenticated using dot1x):
