SLX Linux, boots with bond0 interface with Primary Active eth3 (Physical Management 0 Interface). Interface bond0 is subordinate to vBridge (eth0), which serves as Management 0 interface to SLX Linux and all applications on it. This eth0 is connected though Linux Tap to TPVM eth0. TPVM eth0 contains a separate MAC. The IPv4 address is assigned to eth0 through DHCP or static.
At SLX Linux, the logical proxy interface Eth0.15 or Eth0.32.1 is created to represent the front panel port as a Standby member for bond0.
