FIGURE 3-4The B200x Blade’s Network Interfaces as Displayed by Solaris x86

From FIGURE 3-1and FIGURE 3-4you can see that the bge0 and bge1 interfaces have even MAC addresses and are connected to Switch 0 (SSC0), and that the bge2 and bge3 interfaces have odd MAC addresses and are connected to Switch 1 (SSC1).

The B100x and B200x blades are factory configured so that the base MAC address is an even MAC address.
