When a Cisco router forgets or loses the enable password, there are two ways to recover, depending on which series of routers you are using.
The first of these methods
This approach restores the following routers: Cisco 2000 series, 2500 series, 3000 series, Cisco 4000 series using the 680x0 Motorola CPU, and 10.0 series routers running 7000 versions of
First, the Cisco router to introduce the memory
A router is similar to a computer in that it also has memory, operating system, configuration, and user interface, and the operating system in Cisco routers is calledInternet Operating System (Internetwork operating system) or iOS. The following is mainly about the storage of routers.
ROM: Read-only memory contains a copy of the iOS being used by the router;
Cisco single-ARM routing configuration
One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q.
The difference between dot1q and ISL: dot1q is a generic VLAN protocol model for
There are a lot of users using Cisco routers, So I studied the global debugging of Cisco routers and shared it with you here. I hope it will be useful to you. When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific
I believe that users who use Cisco routers have some knowledge about the configuration of Cisco routers. Here we mainly analyze how to use the Cisco router configuration master port OSOLE to connect VT100 and compatible terminals, and pass Win 3. X or Win 95 terminal simulation program for configuration and other router configuration methods, as a port device con
With the development of China's routing industry, it also promotes the constant update and upgrade of routing technology. Here we mainly introduce the performance and characteristics of Cisco VPN Router, with the development of the Internet, online Communication and transactions have become an important way for people to work. At the same time, network security also mentions the agenda of various enterprises.
In the face of the severe challenges of da

A Cisco router is a network device that connects multiple networks or CIDR blocks. It can translate data from different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network. A vro consists of hardware and software. The hardware is mainly composed of physical hardware and circuits such as the central processor, memory, interface, and control port. The software is mainly composed of the IOS operating system of th
A router is a commonly used network device. How should we configure VOIP implementation? What are the specific operation steps? The following article will give you a detailed introduction.
Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technolo

The concept of UC was first proposed by Cisco. As a result, many leading enterprises have followed suit and proposed their own unified communication concepts. However, as an authoritative Cisco Unified Communication Service, how does one view this market in China? Now let's take a look.
Unified Communication Technology (UC) refers to a new communication mode that integrates computer technology and tradition
Previous articles covered the knowledge of Cisco Unified Communication Platform in terms of telephone products, call processes, and Protocol content. Now let's take a look at Cisco's Unified Communication partner applications. As a Cisco Unified Communication client with rich services, how can we communicate with users?

The features of Cisco Wireless routers have previously been introduced to you. Today, we are trying to better understand the source of the vulnerabilities and the inner relationship between the vulnerabilities and functions. Recently, it was found that Cisco Wireless Router allows hackers to easily access the network configuration page of the router.
1. What are the functions of
Cisco routers use a lot of users, at the same time there will be many problems, the password is forgotten or lost users are very common problems, so I studied the Cisco router password recovery of two methods, here to take out and share with you, hope for everyone useful. When a Cisco router forgets or loses the enable password, there are two ways to recover, dep
With the development of China's routing industry, Cisco Wireless routers are also widely used. Here we mainly introduce a beautiful Cisco Wireless Router WRT54G2, last year, Cisco Consumer Division launched a newly designed 54M wireless route Linksys by Cisco WRT54G2. The elegant and slim design conforms to the current
