Pinging Eth1 direct vs through switch

[EngJay]

I find that if I set an IPv4 address for Eth1, I can ping it with my engineering PC if I am connected through a switch.  However, if I plug the LAN cable directly from the ethernet port on my engineering pc into Eth1 then I can no longer ping the device port.  In this scenario, I would expect to still be able to ping the IP address. What factors should I consider to further assess this behavior?

As eth1 is also an standard Ethernet port it makes no difference if connected via a switch or directly. Did you use an intelligent switch that probably has the IP you pinged? Which system version are you using?

Please beware that eth0 and eth1 must be in different subnets otherwise it could break your communication.

See working configuration on my side (system version 1.16) with direct connection:

Ah okay, I forgot to set eth0 and eth1 on different subnet masks.
