Starting with the Solaris 10 1/06 release, Oracle Solaris supports the following two types of interfaces:
Legacy interfaces – These interfaces are DLPI interfaces and GLDv2 interfaces. Some legacy interface types are eri, qfe, and ce. When you check interface status with the dladm show-link command, these interfaces are reported as “legacy.”
Non-VLAN interfaces – These interfaces are GLDv3 interfaces.
Currently GLDv3 is supported on the following interface types: bge, xge, and e1000g.
