Basic Layer2 Switch

Content

1. Overview2. Transmitting Frames3. MAC Address Table4. Broadcast and Multicast frame

– Address learning– Forward/filter decision– Loop avoidance

Ethernet Switches and Bridges

Cut-Through• Switch checks destination

address and immediately begins forwarding frame.

Fragment-Free • Switch checks the first 64 bytes,

then immediately begins forwarding frame.

Store and ForwardComplete frame is received and checked before forwarding.

Transmitting Frames

MAC Address Table

• Initial MAC address table is empty.

Learning Addresses

• Station A sends a frame to station C.

• Switch caches the MAC address of station A to port E0 by learning the source address of data frames.

• The frame from station A to station C is flooded out to all ports except port E0 (unknown unicasts are flooded).

Learning Addresses (Cont.)

• Station D sends a frame to station C.

• Switch caches the MAC address of station D to port E3 by learning the source address of data frames.

• The frame from station D to station C is flooded out to all ports except port E3 (unknown unicasts are flooded).

Filtering Frames

• Station A sends a frame to station C.

• Destination is known; frame is not flooded.

Filtering Frames (Cont.)

• Station A sends a frame to station B.

• The switch has the address for station B in the MAC address table.

• Station D sends a broadcast or multicast frame.

• Broadcast and multicast frames are flooded to all ports other than the originating port.

Broadcast and Multicast Frames

Redundant Topology Overview

Redundant Topology

Content

1. Redundant Topology Overview2. Broadcast Storms3. Multiple Frame Copies4. MAC Database Instability5. Spanning Tree Protocol

– Redundant topology eliminates single points of failure.

– Redundant topology causes broadcast storms, multiple frame copies, and MAC address table instability problems.

Redundant Topology

• Host X sends a broadcast. • Switches continue to propagate broadcast traffic

over and over.

Broadcast Storms

• Host X sends a unicast frame to router Y.• MAC address of router Y has not been learned by

either switch yet.• Router Y will receive two copies of the same frame.

Multiple Frame Copies

• Host X sends a unicast frame to router Y.• MAC address of router Y has not been learned by either switch.• Switches A and B learn the MAC address of host X on port 0.• The frame to router Y is flooded.• Switches A and B incorrectly learn the MAC address of Router Y

on port 1.

MAC Database Instability

Spanning-Tree Protocol Overview

• Provides a loop-free redundant network topology by placing certain ports in the blocking state.

Spanning-Tree Protocol

• One root bridge per network

• One root port per nonroot bridge

• One designated port per segment

• Nondesignated ports are unused

Spanning-Tree Operation

• Bpdu = Bridge Protocol Data Unit (default = sent every two seconds)

• Root bridge = Bridge with the lowest bridge ID

• Bridge ID =

• In the example, which switch has the lowest bridge ID?

Spanning-Tree Protocol Root Bridge Selection

• Spanning-tree transits each port through several different states:

OAM 802.3ah Overview

OAM Overview

Ethernet OAM protocol for monitoring and troubleshooting Metro Ethernet Networks which can implement on any full-duplex point-to-point

OAM Features

• Discovery Identified the devices in the networks

• Link Monitoring Detects and Indicates link fault

• Remote Failure Indicates a loss of signal ( Link Fault )

and a loss of power ( Dying Gasp )

VLAN Operation Overview

VLAN Operation

Content

1. Segmentation2. VLAN Overview3. 802.1Q VLAN Trunk

Segmentation with LAN Switch

• A switch eliminates the impact of collision through micro-segmentation• Low latency and high frame-forwarding rates at each interface port• Works with existing 802.3 (CSMA/CD) compliant network interface cards and

cabling

Segmentation with Routers

• More manageable, greater functionality, multiple active paths• Broadcast domain• Smaller broadcast

A VLAN = A Broadcast Domain = Logical Network (Subnet)

VLAN Overview

• Segmentation

• Flexibility

• Security

• Each logical VLAN is like a separate physical bridge.

• VLANs can span across multiple switches.

• Trunks carry traffic for multiple VLANs.

• Trunks use special encapsulation to distinguish between different VLANs.

VLAN Configuration Guidelines

– VLAN1 is the factory default Ethernet VLAN.

– By factory default, all ports on BDCOM switch are membership of VLAN1.

– The BDCOM switch IP address is in the management VLAN (VLAN1 by default).

Troubleshooting Switched LANs

Problem: One Device Cannot Communicate with Another

– Make sure the IP address, subnet mask, and VLAN membership of the switch interface is correct.

– If the host is in the same subnet as the switch interface, make sure the switch interface and the switch port to which the host is connected are assigned to the same VLAN.

– If the host is in a different subnet, make sure the default gateway on the switch is configured with the address of a router in the same subnet as the switch interface.

Problem: One Device Cannot Communicate with Another (Cont.)

– If the port is in listening or learning mode, wait until the port is in forwarding mode and try to connect to the host again.

– Make sure the speed and duplex settings on the host and the appropriate switch ports are correct.

– If the connected device is an end station, enable spanning-tree PortFast, disable trunking, and disable chaneling on the port.

– Make sure the switch is learning the MAC address of the host.

Problem: A Device Cannot Establish a Connection Across a Trunk Link

– Make sure the trunking mode configured on both ends of the link is valid. The trunking mode should be on or desirable on one end and on, desirable, or auto on the other end.

– Make sure the trunk encapsulation type configured on both ends of the link is valid.

– On IEEE 802.1Q trunks, make sure the native VLAN is the same on both ends of the trunk.
