Introduction after you log in to the CISCO switch, we will need to use some common operations, such as querying, restarting, and so on, where some of the commonly used operations are grouped together. Query HelpIn different modes, we can enter the question mark directly (? You can query all the commands that you can use in the current mode. When entering a command, if you do not remember the full name of the command, enter the first few characters

LAN is not changed, and the configuration and access control list of the external network Port WAN needs to be changed .Increase the configuration of the VPDN. Assuming the username is admin, password 123456, the configuration process is as follows:This case is XX Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2600 router (dual Ethernet port), IOS 12.2 (), can realize LAN sharing Internet.　　This case configuration is divided i

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP

that the admin domain is able to overwrite all branch switches. The Cisco switch is capable of supporting any media as a trunk, and it can use its own ISL tags for relaying. ISL (Inter-Switch link) is a protocol between switches, between switches and routers, and between switches and servers to transfer multiple VLAN information and VLAN data streams, configured with ISL encapsulation via ports directly connected to the switch, The VLAN allocation a

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 configuration can be done by the TFTP server over the network, through the menu interface provided at startup, and by th

. Currently, most wireless routers only support Web page configuration, rather than Telnet and other configuration modes. Enter the management IP address of the wireless router in the browser, and a login interface will pop up on the desktop. after entering the user name and password, we will enter the configuration interface of the wireless router. After entering the wireless router configuration interface, the system will automatically pop up a "setting wizard ". In the
