The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which means the

It is also helpful to understand some of the knowledge about switch configuration, and here we explain the main statements and procedures for Cisco switch configuration. Last talk with you about how to properly connect the switch, today with some configuration clips to introduce the port configuration. Given that most

Cisco switch Security Lecture Hall: cracking the shock wave virus and the red code, understanding the basic virus principles, and providing a good awareness of cisco switch security. Simple security measures will also receive attention. In today's online world, security is crucial. As the Internet has brought huge bene

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You c

There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are com

With the development of China's routing industry, we have also promoted the update and upgrade of the routing switch technology. Here we have introduced the IOS restoration method of the Cisco routing switch, and we have tried one method, after Flash is deleted, the system cannot be started. You can use X-Modem to restore it. At that time, I accidentally deleted

, the fiber channel switch. Scalability not only refers to the capacity for increasing network bandwidth, but also whether to use the number of ports of existing fiber channel switches to effectively build a large-scale storage network. With the increasing demand for storage networks, users urgently need a high-performance, powerful storage network platform that can meet the bandwidth and port quantity requirements by scaling. Such a platform must be
