Basic Concepts

The concepts described in this chapter are the startingpoint for what an

operator sees, and needs to understand.

4.1

Physical View

The most important concepts are the following:



Ethernet port

is the physical interface between an external physical

Ethernet link and the network processor.



Host port

is the physical interface between the network processor and the

host processor.



Network processor

handles receiving of incoming packets from and

sending of outgoing packets to the Ethernet links. It handles most

switching decisions independently of the host processor.



Host processor

(also called control processor) controls the Network

Processor. This includes assistance in program loading and restart,
executing of control commands and reception of counters. In exceptional

cases the host processor may be involved in switching decisions for
individual packets.

Figure 3 on page 9 illustrates the basic physical view of the EFN234, showing
the listed items.
