cisco qos configuration example

consists of the word Cisco, the value of the startup bit, and the router type or the name of the processor. For example, the boot field on one 4500 is set to 3, and the default boot file name is cisco3-4500. Take the MC3819 (CPU model, mostly Motorola) router startup sequence as an example, the following is the four stages of startup: 1. System Bootstrap 2. S

Routers play an important role in computer networks and serve as a bridge between computer networks. It not only connects to different networks, but also selects data transmission paths and blocks illegal access. Router configuration is not very easy for beginners. We will introduce general configurations and simple debugging of routers for your reference When configuring routers. This article uses cisco2501 as an

is encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA. 1. We recommend that you enable IP Unicast Reverse-Path Verification. It can check the accuracy of the source IP address and prevent certain IP Spooling. However, it can only be used on routers that enabl

Many network administrators ignore security settings when they first use a Cisco router. This article describes how to configure network security when using a Cisco router. 1. Security Configuration of the "Access Control" of the vro 1. strictly control the administrator who can access the vro. Record Filing is required for any maintenance. 2. do not access the v

vswitch, just like a vro. In this mode, we can only view the current configuration, but cannot change the configuration, and the commands that can be used are very limited. Therefore, we must enter the privileged mode. Step 2: Enter the enable command in privileged mode in the previous step and enter the privileged mode. The command format is> enable. Then, enter the privileged mode prompt in switch

"Connection refused by remote host" still appears in telnet host 1015, and an asterisk appears in front of tty. In this case, "clear line tty 68" is required" Terminal Server Configuration: The asynchronous port of the terminal server is connected to the console port of the test router using a Cisco flat cable.Interface loopback0Ip address 1.1.1.1 255.255.255.255ExitaLine 1 16No exec Transport input all Exi

not encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA.8. We recommend that you use FTP instead of TFTP for iOS upgrade and backup and configuration file backup. For example:Router (config) # ip ftp Username blushi

In this section we'll do a HSRP configuration to understand the issue better. To does this we'll use the below the topology [t ' PLD].

You can simply think that GNS3 can not only use the local dynamips as iOS running server, it can also designate a remote UNIX virtual
