The physical Ethernet ports on the backs of the Dell PowerEdge R200, R210, R310, and R320 are labeled as Gb1 and Gb2. The physical (cabling) port called Gb1 corresponds to logical port Eth0. Likewise, the physical port called Gb2 corresponds to logical port Eth1. Throughout this document, when speaking of cabling and physical ports, you must map according to the table below. For example, if a procedure instructs you to connect a cable to an Application Server’s Eth0 port, you must connect the cable to the R210’s physical port labeled Gb1.
