, warning and auditing, intrusion detection, and other aspects. For example, CBAC uses the timeout value and threshold value to determine the session Status and duration. It can clear incomplete sessions and idle sessions for Dos detection and protection. However, the disadvantage of CBAC is that it performs the same review policies on all traffic passing through the interface and cannot precisely control the firewall policies, which is relatively difficult to deploy.To address this problem, a n
With the development of China's routing industry, Wireless routers are also widely used. Here we mainly explain a new Wireless-N Wireless router launched by Cisco, cisco Wireless Router WRT320NWRT320N is the latest Wireless-N Wireless router launched by Linksys. This product

1, Cisco router connection to the ADSL modem configuration: Note: The case for Beijing Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2500 router (dual Ethernet port), IOS 12.2 (T), Be able to realize LAN sha
Global debugging
When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

Cisco router security-TCP connections are common attacks on the network. In fact, most attacks are based on TCP connections, and a large amount of request data is sent to cause Server Denial of Service, is a connection attack. Next, I will take a Cisco router as an example to introduce how to intercept illegal TCP conn
It is very important for Cisco router users to learn about commands for password recovery of Cisco routers. For many beginners, the ROM Monitor of Cisco routers is often unfamiliar or even daunting for a simple reason, first, we do not often use this mode and are not familiar with its related operations; second, Operat
There are still many things worth learning about the Cisco router configuration mode. Here we will mainly introduce how to enter the detailed steps of the Cisco router configuration mode. In the Cisco router configuration mode, th
How should we connect to the Cisco router port? Many people want to know the specific role of the control port and the Auxiliary port. The port content is not detailed on the network. Here is just a few words about the port. The Cisco router port has a control port: the control port console port) and the Auxiliary port
In the BGP Route Selection protocol, you can filter the BGP Route Selection and update. To do this, you need to use the prefix list. I. prefix list features: (1) it can be incrementally modified. We know that we cannot delete an entry in the general access control list, if you want to delete an entry in the list, you can only delete all the entries in the list. In the prefix list, you can delete or Add an entry separately. Www.2cto.com (2) and prefix list can be used in
Dynamic and robust routing is extremely important for Internet networks. Therefore, any network engineer who is first involved in this field must not only understand the concept of routing, but also be able to control it in a real environment. However, the products provided by high-end network equipment suppliers such as Cisco in the routing field are all over the world. This means that most people can only learn routes in school or laboratory environ
Netizens have their own preferences for Cisco router simulation software. The following describes three software models. I hope you can give it a try and give it a better reference to more friends. Everyone should know that the price of a router is very expensive, and it is very expensive to build a router lab.

Many people may not have a special understanding of Cisco router configuration, so I have studied the detailed knowledge of Cisco router configuration. I will share it with you here, hoping it will be useful to you. Have you ever encountered a situation where you have modified the
As the core device of network communication, Cisco routers are widely used. The following is my experience in practice:
Control port interface practices and connections
Connect one end of the control cable RJ45 in the Cisco2500/1000 series router accessories to the Cisco CONSOLE port, and the Cisco7000/4000 series router
This article describes how to configure a vswitch for a CISCO 3550 router and how to configure access control for a MAC address.
In network management, users often encounter this situation: some users violate management regulations and modify their own IP addresses without permission to access restricted resources. Such behavior not only undermines information security rules, but may also cause network comm
In chapter 3 of the Cisco router manual, we will explain the "setup dialog process". This article is taken from the manual. This makes it easier for you to focus on setting up conversations. Global parameter settings, interface parameter settings, and display results. Setting Dialog can avoid the hassle of manually entering commands, but it cannot completely replace manual settings, some special settings mu
