In addition to address binding, ARP configurations of Cisco routers are getting more and more attention. Therefore, we will discuss two aspects here. It seems a bit messy, but I hope it will help you. I know that the command for binding the IP address of the cisco router to the mac address is arp IP address, mac address, arpa, but I think there should be a command that shows the start binding command. for e

Single-user Cisco ProductsSome products of the SOHO series use dial-up technology, such as ISDN Integrated Service data network, which allows users to roam from one place to another, or dial to the central site.The Cisco200 series for ISDN has gradually withdrawn from the market. We recommend that you upgrade it to the 700 series. The 600 series can be used with digital user line DSL) interfaces. The 800 Series features more than the 700 series, espec

There are many knowledge about Cisco routers. Here we mainly analyze the specific methods for Cisco router configuration. Have you ever encountered this problem in daily network management and maintenance: You have been forcibly rejected by a vro or vswitch, a former "friend", because you forgot your password, parameter resetting and information statistics are not allowed. The following describes how to cle

Subnet Mask hardware basic Ethernet protocol Network Management A router is a bridge of a computer network and a core device connecting to an IP network. It can connect different networks, select data transmission routes, and block unauthorized access. Router configuration is not easy for beginners. Take the Cisco router as an example to introduce the general knowledge and configuration of the router for your reference When configuring the ro

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 network administrators who have never heard of this command. Based on my experience, this test is a very useful and powerful command in b

This article describes in detail how to improve OSPF security for Cisco routers. This article describes how to improve network security in terms of protocol analysis and router authentication solutions. OSPF is also an open version of The Link Status Protocol. In practice, OSPF is often used in some large and hybrid networks. In the previous article, I talked about the defects of the RIP Protocol. The reason why network experts develop the OSPF protoc

Hello everyone, the recent development of Huawei is very good, especially in the domestic to Cisco's strategy, many friends will ask me a question, I should go to learn Cisco or to learn Huawei?Let me take this opportunity to discuss with you.Just from the direction of the routing switch (Cisco is called Rs direction, Huawei called the digital direction), technically speaking, the difference is not very lar

In CISCO router products, we usually need to restrict the access of general users during initial configuration. This is very important for Routers. By default, Our routers are an open system and the access control options are all disabled, any user can log on to the device to initiate further attacks, therefore, our network administrator needs to configure a password to restrict unauthorized users from accessing devices through direct connections, CON
