Server using Ubuntu for a multi-port network card with multiple mouth is configured with two IP network segment, in actual use will appear the same network card address corresponding to two IP Settings, ping have a meeting for the two IP impassability, view the arp resolution found another so really only IP without the MAC,
Check the online information found that this is the common problems under Linux multi-port network adapter,
Want to consult everybody here a great god, why two independent network card (not the same card of multiple front-end ports) will not appear this problem, a multi-port network card is actually the public what, only caused this situation,
Also want to ask next, another two front-end ports on the server configuration when the use of the same network segment is reasonable, thank you,

Build a vlan, two mouth assigned to the vlan, respectively set up IP with respect to OK
