How is your switch configured?

The CentOS configuration you described would only work when you set 
GATEWAY, and when the port it's connected to has no VLANs configured for 
untagged access (or no VLANs that you need to access), and when the VLAN 
you DO need to access is tagged.

Are you providing access to one VLAN using tagged packets?
