I believe that many users who use cisco routers have encountered such problems. It does not matter. Next we analyze two common troubleshooting methods for cisco switches. The organization bought a new cisco switch a few days ago, with the WS-X6548-GE-TX, cisco was launched in last April 10 m, 100 m, 1000 M Adaptive 48
This article describes how to make the right choice for a CISCO router. Here I will share some of my experiences in choosing a Cisco router. It may be helpful to everyone.
When deploying a LAN, A vro is one of the essential devices. Cisco is the leader in the field of routers and other network equipment. He is also a brand that many network administrators must co
When routers and switches work normally, you do not need to worry too much about wiring issues. However, when the network encounters problems or changes, wiring knowledge may be of great help to you. In this article, we will introduce you to some basic wiring knowledge, and describe the details of the Cisco console dedicated network cable.
The network cable belongs to the first layer of the Network: physical layer. Only the correct network cable can e
Visio OS opera linux ieCisco Systems IOS is vulnerable to a denial-of-service attack using ICMPRedirect messages.When flooded with ICMP redirect messages, the IOS uses up all its memoryTo store the new host routes. The device is then unable to performOperations that need additional memory such as processing ing routing updatesAnd accepting inbound telnet (1) connections.DETAILSKnown vulnerable combinations:* Cisco 1005 with IOS 11.0 (18)*
It took a few days to write this blog, and the commands for configuring Cisco routers are more clearly written in the tutorials, but many commands remember that they may not be able to be used in the actual network of the enterprise, and I am here to introduce how to log in to the Cisco router using terminal equipment, How to access the configuration network, how to use some of the
Fast Ethernet and Gigabit Ethernet line cards
The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide second, third, and fourth-layer switches and intelligent services with outstanding performance, enabling network control and permanent deployment. These switches provide a variety of Fast Ethernet and Gigabit Ethernet line cards, including desktops, branch backbone and servers for enterprise and commercial exchange solution
A technology, especially network-centric and communication-centric technology, has its own transmission protocol. Now we will introduce some knowledge about Cisco Unified Communication Protocols. So what is SIP when Cisco's unified communication protocol is used? Why is it used?
Support for the SIP protocol in Cisco Unified CommunicationThe SIP Protocol provides a standard-based IP communication method for

Welcome to the network technology community forum, and interact with 2 million technical staff to enter the settings and skills of the two CISCO switches, mainly: Cisco switch setup skills to find the MAC address corresponding to the IP address, cisco switch setup tips: Find the port corresponding to the MAC address on the switch. The IP address of a machine is k
When using a cisco router as an Internet Router, cisco's IP packet filtering function is generally used to count IP traffic. The method is to add the ipaccountingoutput-packets command at each entrance of the cisco router. The cisco router automatically counts the IP traffic of these ports. Common snmp or telnet terminal simulation (showipaccount) methods to obta
After decades of development, from the first four-node ARPANET to the ubiquitous Internet, computer networks have penetrated into our lives. With the explosive growth of the computer network scale, as a router to connect devices also become more important.
When a company builds a network, how to reasonably configure and manage the router becomes one of the important tasks of the Network Manager. This topic describes how to configure a cisco router fro
Install Cisco Packet Tracer in Linux
What is Cisco Packet tracer?
Cisco Packet Tracer is a powerful network simulation tool used for Cisco authentication training. It provides us with a good interface view for various routers and network devices. These simulation devices have many options. Like physical machines, we c
Let's talk about Cisco Huawei and Intel vswitches. The vswitches with Intel are the same as those with other settings. This article mainly introduces the comparison of Cisco, Huawei, and intel vswitches. How to Set Intel vswitches has become a concern. This article provides an in-depth explanation of vswitches in terms of principles, ideas, and testing processes.

Abstract:
The Cisco I-Flex design integrates the advantages of the shared port adapter (SPA) and SPA interface processor (SIP), and uses the extended design to provide service priority for voice, video, and data services. Customers of large enterprises and telecom operators can fully enjoy the higher slot economy brought by interchangeable modular port adapters between different Cisco routing platforms. I-F
Cisco switch security common traffic control and anti-DDoS problems. Recently, cisco switch security has been favored by many friends. Let's have a deep understanding of cisco switch security solutions today! Traffic control, anti-DDoS, virtual lan vlan, and access control list-based firewall functions.
