1) The Cisco router stores several different configuration parameters and stores them in different memory modules. The memory of Cisco Series routers includes ROM, Flash memory, RAM, immutable RAM, and Dynamic memory DRAM. See table 1 ). Generally, when a vrodram starts, it first runs th

During running, RAM contains route table items, ARP buffer items, log items, and groups waiting for sending in queue. In addition, it also includes Running configuration files (Running-config), Code being executed, IOS operating system programs, and some temporary data information. The reading method o

Network is inseparable from the password, as a network administrator to remember more than one router password, if the router password forgotten, we need to set up a router to restore the password.
Router password recovery has a common, that is, let the router start to skip
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

2) If the Break key has been blocked, you can use the cycle Boot Method to enter the rom status. The method is: after the vro is started, the power supply is turned off and the instance is restarted after 5 seconds, generally, it enters the rom status. This method applies to vrouters such as 7500 and 12000.
3) set the baud rate of the Super Terminal to 1200, data bit 8, parity bit 1, stop bit none. Turn on the router power,

When a Cisco router forgets or loses the enable password, there are two methods to restore it, depending on the series of products you are using.

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
Global debugging
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 transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the
It is very important for Cisco router users to learn about how to restore their vro passwords. Here we mainly introduce two methods to help you quickly restore the vro password, when the Cisco Router password is forgotten or the enable password is lost, there are two methods to restore it, depending on the
