In order to improve the LAN operation and maintenance efficiency, we need to accumulate various switch troubleshooting experience at ordinary times so that the switch can be quickly rectified in case of a fault, this article has contributed several

Analysis of cisco switch faults: Protocol errors and insufficient flash space help you solve cisco switch faults. The following protocol errors and insufficient Flash space should be common cisco switch faults. Do you know the general solution? Does

The nine indicators teach you how to deeply set the functions of the Gigabit Ethernet switch. Let's take a look at the following test method for the functionality of the Gigabit Ethernet switch, which is not suitable for you, you can easily learn

Faulty Switch Equipment is still commonly used. So I have studied the cache overflow error caused by the performance degradation of Faulty Switch Equipment. I would like to share it with you here, hoping it will be useful to you. A switch is

Network Environment: Two cisco 4006 switches are connected to each other through two fiber module 1/1-2, and then connected to other network devices or hosts. Fault symptom: The cpu usage of the cisco 4006 switch is too high, and the service is

Information is the most valuable asset of the company. Therefore, ensuring the security and availability of information is an important task of priority. To maximize the value of information, it is necessary to keep the information up-to-date so as

In the traditional Data Center Server area network design, the L2 network is usually limited to the network aggregation layer. By configuring VLANs for cross-aggregation switches, the L2 network can be extended to multiple access switches. This

Whether it's a personalized router or a general-purpose router, which direction will it develop in the future? This is a concern. Heda Bing believes that in the future, routers will develop in three directions: 1. High-speed routing, such as 10g

The performance of a vro determines the efficiency of the vro and the amount of data and applications that you consider when creating a network. The hardware forwarding method greatly improves the data transmission latency and ensures the smooth

Problem:I have a Cisco 2811 router with four T1 v2 wan interface cards. Two wan interface cards are used for dedicated lines. The other two wan interface cards are used to connect to the T1 line of the Internet. Currently, only one line is in use.

Cisco's hot backup routing protocol (HSRP) can provide A backup router when workstation A does not expire, and HSRP can create A virtual router with A virtual MAC address and virtual IP address. Assume there are two routers, Bluestudy A and
