09 STP Principles and Configuration
Trending!
On an Ethernet switching network, redundant links are used to implement link backup and enhance network reliability. However, the use of redundant links may produce loops, leading to broadcast storms and an unstable MAC address table. As a result, communication on the network may deteriorate or even be interrupted. To prevent loops, IEEE introduced the Spanning Tree Protocol (STP).
Devices running STP exchange STP Bridge Protocol Data Units (BPDUs) to discover loops on the network and block appropriate ports. This enables a ring topology to be trimmed into a loop-free tree topology, preventing infinite looping of packets and ensuring packet processing capabilities of devices.
IEEE introduced the Rapid Spanning Tree Protocol (RSTP) to improve the network
convergence speed.

10 Inter-VLAN Communication
Trending!
By default, a Layer 2 switching network is a broadcast domain, which brings many
problems. Virtual local area network (VLAN) technology isolates such broadcast
domains, preventing users in different VLANs from communicating with each
other. However, such users sometimes need to communicate.
This course describes how to implement inter-VLAN communication.

11. Eth-Trunk, iStack, and CSS
Trending!
As services develop and the campus network scale expands, users have
increasingly demanding requirements on network bandwidth and reliability.
Traditional solutions improve network bandwidth by upgrading devices and
implement high reliability by deploying redundant links and using the Spanning
Tree Protocol (STP), leading to low flexibility, time-consuming troubleshooting, and
complex configuration.
This chapter describes how to use Eth-Trunk, intelligent stack (iStack), and cluster
switch system (CSS) technologies to improve network bandwidth and reliability.

12 ACL Principles and Configuration
Trending!
Rapid network development brings challenges to network security and quality of service(QoS). Access control lists (ACLs) are closely related to network security and QoS. By accurately identifying packet flows on a network and working with other technologies, ACLs can control network access behaviors, prevent network attacks, and improve network bandwidth utilization, thereby ensuring network environment security and QoS reliability. This course describes the basic principles and functions of ACLs, types and characteristics of ACLs, basic composition of ACLs, ACL rule ID matching order, usage of wildcards, and ACL configurations.
