cisco 1750 router

Vro is a commonly used network device. I believe everyone knows the importance of backing up the cisco router configuration file. Next we will introduce how to use the COPY command to back up the cisco router configuration file, and how to COPY and back up the cisco

1. TELNET Remote logon Configuration 1. Configure the Logon account, password, and account level on the CISCO router, as shown below. The account name is abc, the password is abc123, And the account level is 15 to the highest level) R1 # configure terminal R1 (config) # username abc privilege 15 secret abc123 R1 (config) # end R1 # 2.

1. Preface A large number of Cisco routers are used in Jiangxi IP networks. Administrators usually use Telnet to remotely log on to the vro for routine maintenance. Because Telnet, FTP, and other network service programs use plain text transmission passwords and data in the network, their security cannot be effectively guaranteed. Once the Administrator's user name and password are intercepted by someone with ulterior motives, the consequences will b

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 se

The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implem

Implementation of ADSL access using the cisco 2500 router Description: This case is Beijing Telecom's adsl PPPoE access. A common adsl modem and a cisco 2500 router (dual Ethernet port) are required, and IOS 12.2 (15) t, can achieve LAN Internet sharing. in this case, the configuration is divided into seven steps: www.

NAT configuration on a CISCO router is in full swing and causes the shortage of IP addresses. to alleviate this problem, an important application is NAT (Network Address Translation ), it is widely used. Through address translation, NAT enables enterprises to access the Internet by using only a small number of valid IP addresses on the internet, effectively alleviating address insufficiency, at the same tim

The market demand for Cisco routers is still very high, so I studied the knowledge about the default password of Cisco routers and shared it with you here. I hope it will be useful to you. The following are some default initial IP addresses, user names, and passwords used for Factory installation of ADSL, which must be known for debugging. There are three methods to debug these settings: One of the most c

China Mobile's GPRS network uses the APN method to connect to the GPRS device terminal and communicate with the server through the APN. The customer purchased the Cisco 2811 router, and the mobile company needed to pull the optical fiber through the E1 port, I spent more than 1000 RMB with an E1 module. mobile companies are doing very poorly, and optical fiber connectors are not provided at all. I also boug

For Cisco router authentication, when performing the cisco Route Selection protocol (r12002; VPN) authentication, the key is irrelevant to the key ID when using plain text (General authentication, during MD5 authentication, the key and key ID are related, that is, the key IDs and keys at both ends must be the same, for example, R1 (config) # key chain key1 R1 (co
