Go to the configuration menu and select "Clear Non-Volatile RAM" to Clear all Cisco router configuration information including passwords of the
management address, which is disabled by default and needs to be opened manually.
The permission levels on Cisco devices are from 0 ~ 15. The default Telnet mode is 1, and the maximum permission is 15. (Privilege level [0-15])
The login function is enabled for the vty line by default, which means you must set a password for it to log on.

With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with thei
following example:Example 1. Pix525 (config) # fixup protocol ftp 21Enable the ftp protocol and specify the ftp port number as 21.Example 2. Pix525 (config) # fixup protocol http 80Pix525 (config) # fixup protocol http 1080Specify port 80 and port 1080 for the http protocol.Example 3.

It's classic. I use it.DeploymentsThe deployments in this document were implemented in an isolated lab environment. the deployments were cleared by issuing the write erase command on the routers, and the clear config all command on the switches to ensure that all devices have a default configuration. make sure you understand the potential impact of any configuration or command on your network before using i
. Setting up TelnetTelnet has a version of the change. Before the PIX OS 5.0 (the version number of the PIX OS), the PIX can only be accessed via Telnet from hosts on the internal network. In PIX OS 5.0 and later versions, Telnet to PIX Access can be enabled on all interfaces. When you want to telnet to the PIX firewall from the external interface, the Telnet traffic needs to be protected with IPSec, which means that the user must configure the PIX to establish an IPSec tunnel to another pix, ro
can run normally. However, it makes sense to rename a vro and uniquely identify it. Example:
Router (config) # hostname Router-Branch-23
In addition, you can configure a domain name on the router so that it knows which DNS domain it is in. Example:
Router-Branch-23 (config) # ip domain name TechRepublic.com

The following is a brief description of the configuration steps of 5505:1. Supervisor Engine Software Configuration:First, the Supervisor Engine Module needs an in-band (sc0) interface IP address, which is a manageable address and can be managed by telnet or SNMP for 5505. There is also an SLIPsl0 interface, which is not commonly used and is not described here.The default IP address of sc0 is 0.0.0.0, which belongs to vlan1. VLAN1 is the default VLAN
The Cisco 2511 router configuration method is used as a port device to connect to the WAN. The router has been widely used. Its main function is to connect multiple independent networks or subnets, achieve optimal path finding and data transmission between the Internet. This article takes the Cisco 2511 vro as an example

There are many IOS skills on the Internet, but most of the best skills are not enough to form a complete article. Today, I want to use one of the Chinese IT labs to describe five tips for using Cisco IOS. I believe these skills will definitely make the network administrators work more efficiently.

The network topology is: The central switch uses Cisco Catalyst 4006-s3,supervisor Engine III G engine in the 1th slot, for three-layer exchange, 1 24-Port 1000base-t module in the 2nd slot, for connecting to the network server; The 1 Block 6 Port 1000base-x module is located in the 3rd slot for connecting 6 backbone switches. One switch uses Cisco Catalyst 3550-24-emi and
Routers are packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer. Routers implement network interconnection by forwarding packets. Although routers can support a variety of protocols (such as TCP/IP, ipx/spx, AppleTalk, etc.), most routers in China run TCP/IP protocol. Routers typically connect two or more logical ports identified by an IP subnet or Point-to-Point protocol, with at least one physical port.
The router determines the output port and t
