NET1L - Lesson 7 (Ethernet Switching)

Also called CAM Table (Content Addressable Memory) Table.

• MAC Address Table

• Routing Table

• IP Address Table

Ethernet operates in the ___________ and the physical layer.

• data link layer

• network layer

• transport layer

It is a family of networking technologies defined in the IEEE 802.2 and 802.3 standards.

• Ethernet

• WLAN

• Wi-Fi

• Bluetooth

The 802 LAN/MAN standards, including Ethernet, use two separate sublayers of the data link layer to operate:

• LLC Sublayer

• MAC Sublayer

• IP Sublayer

Places information in the frame to identify which network layer protocol is used for the frame.

(IEEE 802.2)

• LLC Sublayer

• MAC Sublayer

Responsible for data encapsulation and media access control, and provides data link layer addressing.

(IEEE 802.3, 802.11, or 802.15)

• LLC Sublayer

• MAC Sublayer

IEEE 802.3 data encapsulation includes the following:

• Ethernet frame

• Ethernet Addressing

• Ethernet Error detection

• Ethernet Forwarding

This is the internal structure of the Ethernet frame.

• Ethernet frame

• Ethernet Addressing

• Ethernet Error detection

The Ethernet frame includes both a source and destination MAC address to deliver the Ethernet frame from Ethernet NIC to Ethernet NIC on the same LAN.

• Ethernet frame

• Ethernet Addressing

• Ethernet Error detection

The Ethernet frame includes a frame check sequence (FCS) trailer.

• Ethernet frame

• Ethernet Addressing

• Ethernet Error detection
