2618 switch version upgrade Experiment 1 knowledge Prepare to understand the file system of the switch, and have mastered the configuration methods of layer-3 address 2618. 2. The purpose of this experiment is to learn how to upgrade vswitch 2618 in

Huawei S5700-28C-EI-24 optical fiber switch and Huawei S2326-EI connected to a company's network core network transformation, core equipment new procurement of S5700-28C-EI-24S 10-Gigabit optical fiber switch (four photoelectric multiplexing port),

Cisco switch port link type description: vlan description 1. an Access port can only belong to one VLAN and is generally used to connect to a computer. 2. A Trunk port can belong to multiple VLANs and can receive and send packets from multiple VLANs.

Analysis of the working principles of bridges and L2 switches-video notes: the working principles of bridges (L2 switches) and security threat hubs are rarely used. Pay attention to the knowledge of bridges. The characteristics of a bridge and a

Using the raw socket to measure the forwarding table capacity of the link layer switch using the original socket, we can build data frames in the network according to our own ideas. Because it is for the Ethernet frame at the link layer, we do not

Port-channel experiment and TestWhen two switches use layer-3 + layer-2 for connection interruption, there will be about 10 seconds for reconnection. It is best to specify the protocol and initiative when creating a PORT-CHANNEL. In interface mode,

It may take 30 seconds or more to connect a computer to a vswitch before the computer can communicate over the network. If you are waiting for a long time, 30 seconds of waiting will make you feel very long. Let's take a look at how to accelerate

With the increasing development of the telecom market and the gradual evolution to the Next Generation Network (NGN), The Softswitch technology is playing a key role and is increasingly becoming the technical link for circuit switching and group

  Ling huchong entered Huashan when he was 14 years old, and Yue linshan was eight years old. During the day, Yue wuqun gave two people a guide to jianfa. At night, Ling huchong told her story to tell her to fall asleep. Later, Yue Bu group received

If you are still using Huawei's HW-RouteSim to simulate H3C routers and switches, we recommend using H3C simulation software (H3C-simware ), similar to the system software used by H3C products, it can simulate all routes and exchange commands of H3C

Hubs, switches, and routers, which are known as network hardware, have always been active in the network field. However, many cainiao who are new to the network are annoyed by the fact that, they are not only similar in appearance, but also often

There are three switch modes: storage forwarding, fast forwarding, and segmented forwarding.1. CSMA/CD (Multi-Channel Access for carrier listeners with conflict detection)Working principle: Listen to whether the channel is idle before sending. If it

Lab objectives:Understand the basic principles of Virtual LAN (vlan;Measure the test taker's knowledge about how to configure a vswitch to divide VLANs by port;Measure the test taker's knowledge about Tag VLAN configuration.Technical Principles:1.

  In general, there are several VLAN users in the network and three egress ports. Set a policy route on the core switch so that the core switch will decide to drop the database to one of the three egress based on the pre-configured ACL stream

  Step 1: ensure that the stack environment 1. the IOS version must be the same 2. The stack line connection is correct Step 2: Start the MASTER you think. Note that other devices cannot add points at this time. Wait for the MASTER to load IOS,

L2 switching principle:1. receive all data frames in the network segment;2. Use the source MAC address of the received data frame to create a MAC Address Table (Source Address self-learning), and use the update and aging mechanism to maintain the
