This chapter describes the interfaces that the SBx3112 supports.
• Interface Types
• GE Interfaces
• XE Interfaces
2.2 Interface Types
2.2.1 Introduction
An interface is a capability associated with a physical port. The interface, therefore, provides a logical repre-
sentation of one or many physical ports. A specific instance of an interface has an identifier which can be used
when configuring these capabilities.
The relationship between interfaces and physical ports can vary from one-to-one to many-to-many. This means
that one port can have more than one interface type and an interface type can use more than one port.
For the SBx3112, there are the following interface types:
• Ethernet - Each instance having a Type of ETH, an ID of the port number, and no name. The management
interface has an interface of ETH:0 and has a category of General.
• LAG - This occurs when a LAG is created, and has a Type of LAG, an ID of 0.0 (first), and associated ports
that depend on the ports that have been chosen to be part of the LAG group.
• VLAN - This supports the INBAND and ethernet module interfaces.
• GE - This is used when changing attributes for the interface and for profiles.
• XE - This is used when changing attributes for the interface and for profiles.
