By configuring the basic access control list, you can achieve ~ Filter packets sent from hosts whose source IP address is 10.1.1.2 within; www.2cto.com 2. the Advanced Access Control List must be configured to prohibit mutual access between the R D department and the Technical Support Department, and restrict

Example of RADIUS authentication, authorization, and billing configuration for 18.6.3 802.1x users In 802.1x authentication, the use of remote RADIUS servers is the most commonly used AAA access control, and the RADIUS server can not only realize the required authentication of 802.1x users, but also authorize and charge them. This example topology, as shown in Figure 18-6, uses a RADIUS server that is widely used by the H3C company to develop the IMC

H3C layer-3 Switch configuration: analyzes VLAN code instances. Currently, there are a lot of people using layer-3 switches, and maintenance of switches has become a problem that cannot be ignored. Only the three-tier switch is configured, which not only saves your time and effort on accessing the Internet, but also brings more highlights to your network life. No

The two days of laboratory network did not give force, and later found that someone occupied the lab too much bandwidth, and landed in the laboratory old H3C s5500 switch to see the port traffic situation is very inconvenient, so the initiation of writing a small tool to statistics port traffic situation, has sought to find who occupied a large amount of bandwidth.So I looked up and found that Python had a

Therefore, I configure an IP address in the same network segment for VLAN10 to communicate, but the default Management VLAN of the switch is VLAN1, therefore, we need to cancel VLAN manage

The h3c layer-3 Switch acl is an example of a new library that can only access the electronic reading room, and cannot access other hosts on the Intranet, so as to avoid security impact. the IP address of the On-Internet www.2cto.com electronic reading room is not opened to 10.0.1.9, the new library plans to divide vlan 11, network segment 10.1.11.0/25, and vlan-int 11 IP address 10.1.11.1.

ARP attacks are a common network problem. Therefore, you must configure an appropriate switch device. The following uses H3C devices as an example to describe typical configuration methods. 1. arp attacks to prevent counterfeit gateway IP addresses 1.

In fact, we have also talked a lot about how to configure static routes. Here we mainly analyze the specific methods for configuring static routes for H3C switches for three switches. I hope you will have a lot of gains after reading this article, I also hope this article will teach you more things. I. Networking requirements: As shown in, by configuring static routes on the three switches, the three PCs in different network segments can communicate w

H3C switches usually create a group with the interface Bridge-Aggregation1 while performing aggregation, and then create a group with the link-aggregation group 1 manal. The main difference is the vswitch system version. In earlier versions of V3, link-aggregation group 1 manal was used to create a group. The current version of the V5 platform uses the interface Bridge-Aggregation1 to create a group. View the display version The Version is as foll

Experimental background: As the size of the company continues to expand, the network department at the same time applied for two optical fiber, one of the 10M, the other one for 20M, due to bandwidth asymmetry, the requirements in the three-tier switch to do a strategic route to achieve 2:1 of the traffic allocation, followed by two lines to each other, so as to achieve a safe and reliable network transmission Experiment Network topology diagram:

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a typical three-layer switch, the communication between broadcast domains is usually impleme
