Looks that I need to study some Linux.
As I do not know these Ops, I am not sure based on the info you provided.
But something I can not understand:
1, from the configuration, your port E0.5 encapsulate Ethernet, not 802.1Q, I do not think this is VLAN 5, just the sub-interface;
2, Can I assume that the E0 and E0:0 are separate NICs in your PC2? If I can, from the TCP/IP perspective, I do not know why they can be configured in the same subnet. Maybe it is allowed in Linux?
Other concerns about this case:
1, if all of these three ports in the switch are in the same VLAN?
2, if your PC2’s Eth0 enabled ARP PROXY?
All of my thoughts are based on TCP/IP, I do not know anything about Linux.
If you are interested in talking it deeply, please send me your msn.
