Necessity for configuring WRED on a Cisco Router Although the queue provides VoIP QoS congestion management, it still needs some congestion avoidance mechanisms, such as WRED. In particular, WRED can prevent the output queue from reaching the limit value, which will lead to the loss of all input packets. This article comes from Informit and discusses the necessity of configuring WRED on a

: single two-way authentication: www.2cto.com 2.2, CHAP authentication: CHAP: Challenge Handshake Authentication Protocol, full name: challenge Handshake Authentication Protocol. CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified after the link is established. CHAP is safer than PAP because CHAP does not send plain text online, but instead sends a random number s

This article uses VPN technology to achieve interconnection between two parts of the network, simulate ISP, close to practicality, the article mainly shows us the specific operation steps, mainly the input of basic commands. In this experiment, we use the Cisco 2600 router and VPN technology to achieve the network interconnection between one branch and two parts. To stay close to practicality, we still use

Cisco once again launched a new generation of router products and also applied new technologies. So I studied how Cisco developed the new VQE technology to solve the problem of IPTV Video Delivery. Here I will share it with you, I hope it will be useful to you. Cisco has announced the release of the VisualQualityExperi

Cisco IOS is a dedicated kernel that provides routing, switching, network interconnection, and remote communication capabilities. Most Cisco routers are running iOS, and more and more Cisco Catalyst switches are running it, including Catalyst2960 and Catalyst3560 series switches. Some important aspects of the Cisco

In Cisco router configurations, NAT configurations are frequently used. I hope the introduction below will be helpful to the majority of fans. It is a common method. The vro performs simple NAT translation and sets a CIDR Block in the NAT address pool. After a while, I found that the address pool was a waste of time. When I wanted to use a real ip address, I couldn't use it, so I decided to modify the

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users using the following command:Privilege EXEC l

Some time ago, someone familiar with me asked me how to set up a bridge on a Cisco router )? At that time, due to the relationship between work, I just briefly talked to him. Today, we set up a Cisco router as a complete configuration command for bridging. Through this instance, you can learn how to use a

address of the TFTP server be entered. After the Server IP address is correctly entered, the router also requires the network administrator to provide the configuration file name to be backed up. Generally, we recommend that you use a file name that is easily remembered by the Administrator. At this time, the router will prompt the Administrator to press YES to confirm the operation. 3. copy tftp running-c
