If there is an entry in the routing table for this address, then it sends out the frame out that interface.

Then the switch checks the destination MAC address.

If its is not found in the table, the switch creates a new entry.

The switch then checks this MAC address against its MAC address table.

The switch examines the source MAC address, which is the physical address of Client 1 - 1111.1111.1111.

Essentially, they tell the receiving node to get ready to receive a new frame.

An ethernet frame is received on switchport Gi0/1. Each frame starts with a 7 bytes preamble and 1 byte start frame delimiter (SFD) as shown in figure 1. These first 8 bytes of the frame are used to get the attention of the receiving node.

Let's look closely at each steps the switch takes:

The process starts when Client 1 sends an Ethernet frame to Client 4. Figure 2. LAN Switch forwarding frames and learning MAC addresses

The switch hasn't yet created any entries in its MAC address table. Shown in figure 1 is a single-switch topology. Also, switch's MAC address table is also called switching table and CAM table (Content-Addressable Memory Table). It is important to mention that the term switchport and switch interface are used interchangeably. This document describes the configuration of Ethernet services, including configuring link aggregation, VLANs, Voice VLAN, VLAN mapping, QinQ, GVRP, MAC table. When a frame is received on a switch port and the source MAC address is not known, the switch creates a new entry in the MAC table. Switches build their MAC address tables by examining the source MAC address of incoming Ethernet frames. Let's start with the process of receiving frames and learning MAC addresses.

Forward the frame out single port or forward a copy of the frame out multiple ports, if the frame is either unknown unicast or broadcast one. Connect to HP ProCurve Switch 5400 and make the following changes to its configuration (change the IP address of the RADIUS server and the password to your.

Decide where and how to forward the frame based on the destination MAC address.

Receive an Ethernet frame, examine the source MAC address and update its MAC address table. The bdinfo command (short: bdi ) prints the information that U-Boot passes about the board such as memory addresses and sizes, clock frequencies, MAC address.

The switch logic can be summarized in a few steps: When a switch receives a frame, it follows a set of rules and ultimately makes a decision out of which port or multiple ports to towards the frame. To achieve that goal, switches make decisions based on the source and destination MAC addresses in the Ethernet frames. A LAN switch's ultimate role is to forward Ethernet frames.
