[CISCO] NAT configuration full guide vronat NAT Function configuration introduction with the rapid development of the internet, the shortage of IP addresses has become a very prominent problem. A variety of solutions have emerged to solve this problem. The following describes an effective method in the current network environment: address translation (NAT. 1. NAT

This article describes in detail how to configure the NTP time synchronization server, and takes CISCO 7200 as an example. I hope this article will help you. For the purpose of network management, we set up netflow to monitor traffic and obtain detailed access records for Intranet users to access the Internet. Such records can be accurate to seconds, the premise is that the time of the monitored vro or vswi

complete, you can use the "show vlan #" command to display a specific vlan information and verify VLAN parameters. For example:Switch # show vlan 3 2. configuration of multiple switchesTo allow a VLAN to span multiple switches, you must configure the trunk (trunk) to connect to these switches. Cisco requires that trunk protocols such as ISL be used on such trunk links, so the command to enable trunk protoc

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protoco

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

192.168.61.128 as the remote server IP address of GNS3, perhaps everyone is more curious about the configuration of the address there is no need to pay attention to the place, the answer is there, as long as the IP address to the IOU virtual machine IP address.In fact, this place is currently reserved for IOU settings. 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

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

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

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.

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
