For enterprise users, multi-device port access control can optimize the network more reasonably. Here we analyze in detail how to configure a Cisco router to implement this function. You only need a CISCO router with an asynchronous module or a

The rgmp protocol acts between multicast routers and switches. Rgmp allows you to fix multicast data packets forwarded by vswitches in the required vro. Rgmp is designed

The port Mapping method enables access to specific port services from the Internet to the local area network internal machines. For example, the machine you are using is in a LAN connected to the Internet, all the services you open on the machine (such as FTP), by default, the outside world can not access. This is because your IP is the LAN internal IP, and the outside can access only the server you are con

NAT configuration instance for cisco router with port ing If the ISP provides many IP addresses, you can use NAT to map an external address to each server. However, if it is not the case (for example, if it is only two times), there are four servers in the Intranet that need to provide external services, one for Intranet address translation and the other for prov

There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology. Generally, a router is a bridge between a LAN and a wan. The so-called router's own backup technology is designed to solve a router's own hardware (such as memory, CPU) or software IOS fault or local port fault, network

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:◆

Client list: You can view all active users of the Cisco wireless router configuration through the client list function.Static Address Allocation: Through the static address allocation function, you can specify an IP address for the PC on the vro side and an IP address based on the MAC address of the NIC on the PC side. 4.
