My linux box, running with Centos-5.5, is showing up (??) a pseudo network interface for Eth0. On Switch where my Eth0 is connected, observed 2 MAC-Addresses. If a DHCP server present in LAN, the second pseudo interface is picking up a DHCP IP Address too. Furthermore you can ping both Eth0 ip and Psedo Eth0 IP from the switch. The intensity of the problem is more when port-security is configured on SW for that port.
“ifconfig –a” is not showing that pseudo interface.
Show us the output of ifconfig -a
