There are still many things worth learning about the Cisco router configuration mode. Here we will mainly introduce how to enter the detailed steps of the Cisco router configuration mode. In the Cisco router configuration mode, th
communication. The NetEye firewall comes from people's security requirements. Whether data packets can be correctly arrived, the arrival time, and the direction are not the focus of the NetEye firewall. The focus is on this series.) whether data packets should pass through and whether they will cause harm to the network. 2. Different fundamental purposes The fundamental goal of a vro is to keep the network and data accessible ". The fundamental purpose of the firewall is to ensure that any non-
I. i0s process The i0s process is a special software task that runs on a router and is used primarily to implement a function. When we configure i0s with the command-release profile, it is actually the same as controlling the behavior that makes up the 10S processes, all of which run concurrently on the router. The number and type of processes that can be run on one ro
, that is, start directly, so that the password does not work. (3) Reboot the router. (4) After the router starts to enter the privileged mode, executes the CONFIGMEM command, maintains the previous configuration information to be valid. (5) At this time can be normal operation to view the original password, of course, the need to do here is to change the password for their familiar, difficult to forget.
In the real world or laboratory environment, Cisco IOS test commands are very useful and powerful commands. Learn the basic usage of this command and learn a few useful sub-commands. This is not surprising if you have never used the Cisco IOS test command. I have met many ne
Network security management involves many aspects. However, looking at many security events, we can draw a basic conclusion that the harm is caused by ignoring basic security measures. This article will discuss the importance of maintaining Cisco Router password security, explain the three modes of Cisco router IOS, an
router. In addition, when there is no need, why do you restart a vro and sit down and wait? You can also use the copy startup-config running-config command. However, what this command does may not be as you think. It only combines the commands in startup-config with those in running-config. If there is a conflict, it will leave the command in running-config. As a result, what you get is a mixture of
" is the MAC address of the NIC. For Windows 2000/XP, enter "ipconfig/all" at the command prompt ". In the displayed list, "Physical Address" is the MAC Address, and "IP Address" is the IP Address. to bind the two, enter "arp-s your IP Address, your MAC Address ", for example, "ARP-s 192.168.1.5 80-00-0B-B4-36-70 ". Question: How can I configure static ARP on a Cisco ro
connection with the server on behalf of the client, if both connections are successfully implemented, the Cisco router will transparently merge the two connections. The router has more strict timeout restrictions to prevent its own resources from being exhausted by SYN attacks.2. In monitoring mode, the Cisco
In chapter 3 of the Cisco router manual, we will explain the "setup dialog process". This article is taken from the manual. This makes it easier for you to focus on setting up conversations. Global parameter settings, interface parameter settings, and display results. Setting Dialog can avoid the hassle of manually entering commands, but it cannot completely repl

Check the port configuration and route configuration of Cisco 3640, and find that the port IP address is configured normally, but there are two routes in the route list: Ip route 0.0.0.0 0.0.0.0 192.168.10.2 Ip route 0.0.0.0 0.0.0.0 10.255.12.254 Because the Department's network is the lowest subnet in the Unit's Wan, the whole unit's Wan is accessed according to business needs, and the Department's
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 stora

A Cisco router uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4, And the L2 Switch uses two Cisco 2950, A layer-3 Switch uses a Cisco 3550. There are two VLANs in the network. To simplify the descriptio
supports SSH. log on to your vro or vswitch and check whether you have loaded an IPSec IOS image that supports SSH. In our example, we will use the Cisco IOS command. Run the following command: Router> Show flash This command displays the name of the loaded IOS image. You can use the result to compare the list of supported features of your supplier. After you ve
Cisco router configuration mode In general, you can configure your router in 5 ways: 1.Console Port connection terminal or running terminal simulation software of the microcomputer; 2.AUX Port Connect modem, connect with remote terminal or computer running terminal simulation software by telephone line; 3. Via the TFTP server on the Ethernet; 4. Adoption of
CHAP (Challenge Handshake Authentication Protocol) and PAP (Password Authentication Protocol) are generally used to provide security Authentication on PPP encapsulated serial lines. With CHAP and PAP authentication, each Cisco router is identified by a name to prevent unauthorized access. Task commands Set the PPP encapsulation ppp1 Set the authentication method
The command line port of a cisco router uses a hierarchical structure, which requires logging on to different modes to complete detailed configuration tasks. From a security perspective, cisco IOS divides EXEC sessions into USER mode and privileged mode. Features of the USER mode: In USER mode, only basic monitoring command

Software connection As mentioned above, if the terminal used for 10 s configuration is a PC, you must run the terminal simulation software so that we can enter 10 s commands and view IOS information.
