Classification and markingTags can be marked with the high three-bit (IP priority) or high six-bit (DSCP) of the TOS in the IP header.On R1, the priority of ICMP traffic is set to 2, the DSCP value of the HTTP traffic is set to AF22, the other unmatched traffic p

Vswitch span technology Overview + Cisco configuration example 1. Introduction to span The span technology is mainly used to monitor data streams on vswitches. It can be divided into two types: Local span and remote span.---- Local Switched Port Analyzer (SPAN) and remote span (rspan) have slightly different implementation methods. Using the span technology, we c

An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the

I came back again, the last two articles introduced the Huawei Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.First, the topological enviro

Vswitch QoS application configuration: control your speed and bandwidth, master the following knowledge about vswitch QoS application configuration, you can easily select your preferred vswitch QoS application configuration method

action is actually executed. The default action is permit. What is the difference between the port-based CAR and the global-based CAR-based port-based CAR? The speed of this port is separately enjoyed, while the global-based CAR-based port is equivalent to sharing all ports. For example, CAR 5000 kbit/s. If the application is under the port, the port speed is limited. The maximum rate of sent or received packets is 5000 kbit/s. If the application is

, Citrix, routing protocol, etc.) traffic and other network traffic Web emails ). With network-based application recognition (NBAR) monitoring in Cisco SDM, users can inspect application-layer traffic in real time in a visualized manner, and continuously analyze the impact of QoS policies on various application traffic. Monitoring and Troubleshooting In monitoring mode,

RSVPResource Reservation Protocol is used in Cisco router configuration to control data traffic, ensure voice quality, and meet QoS requirements. The router parameters are configured as follows: 1. Take the vro parameter settings of the municipal branch as an example) Hostname WZ! Configure the POTS Dial-Up peerDial-p

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in

Comments: This article describes the basic configurations of Cisco routers. The configuration process of Cisco routers is still complicated, and there are many factors to consider, especially in terms of security. In fact, there is no need to make the router think so complicated. In fact, the router is a computer with multiple ports, but it plays a different role

The market demand for Huawei routers and CISCO routers is very high. So I studied the differences between the configurations of Huawei routers and CISCO routers. I would like to share with you here, hoping to help you. The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are e

There are many things worth learning about in the configuration of a Cisco Wireless Router. Here we mainly introduce how to use a vro to set up a PC to share the Internet, including knowledge about DHCP, security, TCP/IP network protocols, and so on. As a product designed specifically for broadband Internet sharing, a Broadband Router has the advantages of simple and convenient Internet sharing, high securi

The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are exactly the same, and some of them have also been improved according to the needs of domestic users. For example, the configuration and debugging interface that can be switched between Chinese and English makes Chinese u

This article mainly introduces how to configure the vro for Cisco IOS configuration lock to prevent configuration disorder. I believe this article will help you. If multiple network administrators connect to the vro at the same time to modify the configurations, the changes may be lost or only part of the content can be executed, resulting in problems in the oper

that you need a user and a password to gain access. In addition, we recommend that you use a secret password for your username, instead of a common password. It uses MD5 encryption to encrypt passwords, and greatly improves security. Example: Router (config) # username root secret My $ Password After the user name is configured, you must enable the port using the user name. Example:◆ Router (config) # line

Users using Cisco routing, many of them do not pay much attention to doing Cisco router configuration work, in fact this is a very important part, especially for our network security. There are several ways to do Cisco router configuration. The
