1.7 Interface management
1.7.1 Introduction
Ethernet is a very important LAN networking technology which is flexible, simple, and easy
to implement. The Ethernet interface includes the Ethernet electrical interface and Ethernet
optical interface.
The ISCOM2600G-HI series switch supports both Ethernet electrical and optical interfaces.
Auto-negotiation
Auto-negotiation is used to make the devices at both ends of a physical link automatically
choose the same working parameters by exchanging information. The auto-negotiation
parameters include duplex mode, interface rate, and flow control. Once successful in
negotiation, the devices at both ends of the link can work in the same duplex mode and
interface rate.
