cisco switch 10gb ports

technical convenience for the design of different types of cisco Gigabit Switches. Next, we will show the design principles and architecture of different types of cisco Gigabit Switches one by one, to help you determine what kind of cisco Gigabit Switch is what you really need. Stackable

This tutorial describes how to start and configure Cisco Catalyst 1900 series switches.1. Tutorial PurposeThrough this experiment, you can master the following skills:Familiar with switch startup interface;Configure the vswitch;Understand the port number of the vswitch.2. device requirementsThis experiment requires the following devices:One Cisco Catalyst 1900 Se

The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traff

important to protect the switch from unauthorized control. Because if a hacker controls a host and a subset of switches, he will be able to use Span/rspan and sniffer to eavesdrop on any information transmitted over the network.First explain port mirroring: Port Mirroring simply put, the switch one (a number of) ports (source port) of the traffic completely copy

switch to automatically learn to bind, this configuration is saved in the MAC address and in the running configuration file. If you save the configuration, you do not have to re-learn the MAC address after the switch restarts, although the sticky and reliable MAC address can be manually configured, CISCO does not recommend this. The command is as follows:

/5), round-trip min/avg/max = 1/1/4 MS 6509 MSFC # show arp | in 10.10.1.65 Internet 10.10.1.65 2 0006.2973.121d ARPA Vlan2 Through the above Cisco switch setup command, we know that the MAC address of 10.10.1.65 is 0006.2973.121d, which is the MAC address expression of IOS devices. In CatOS, it should be written as 00-06-29-73-12-1d. 　　Cisco

DDoS attacks. VLAN A virtual LAN is an essential security feature of cisco switches. A VLAN can implement a limited broadcast domain on a layer-2 or layer-3 switch. It can divide the network into independent areas and control whether these areas can communicate. A VLAN may span one or more switches. It is independent of their physical locations, and devices communicate with each other in the same network.

there are many cables on the switch. With the naked eye, it is difficult to accurately identify idle ports at once (if an error is accidentally pulled, the Network may fail). Therefore, we used to log on to the switch, run the following command: 3550 # show inter. At this time, the switch will display the details of e

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

. Breakthrough Cisco switch cluster technology You can use the new Cisco switch cluster technology to achieve scalability and manageability beyond the stack. You can configure any Catalyst 3500 XL series or 2900 XL series standard or enterprise switch as a "command"

network functions from Layer 2 to Layer 7 to increase revenue and increase user productivity. The Catalyst 65 million M Ethernet cisco switch module provides a wide range of optional features, including: support for new bandwidth-intensive applications-support for new applications with high bandwidth requirements, including Storage Networking, electronic learning, image processing, 3D modeling, and network

routing switch and Hub. The fast port no longer experiences the four states of the spanning tree and goes directly into the forwarding state to improve the access speed. Pconline1 (config) #interfacerangefastethernet0/1-20/* to 1-20 port configuration; Pconline1 (Config-if-range) # switchportmodeaccess/* set port to access mode; Pconline1 (config-if-range) #spanning-treeportfast/* set 1-20 port to fast port. The

switch kernel becomes a bottleneck for performance implementation; the second is the cross-bus structure. It can establish direct point-to-point connections between ports, which is good for single-point transmission performance, but not suitable for multi-point transmission. The third is the hybrid cross-bus structure, this is a hybrid cross-bus implementation method. Its design idea is to divide an integr

network cable, but there are many cables on the switch. With the naked eye, it is difficult to accurately identify idle ports at once (if an error is accidentally pulled, the Network may fail). Therefore, we used to log on to the switch, run the following command: 3550 # show inter. At this time, the switch will displ

switch with two 100M upstream ports. These switches cannot be extended except for limited software upgrades; The other is a modular switch, mainly refers to 4000 and more models, network designers can according to network requirements, select a number of different models of interface boards, power modules and the corresponding software. When choosing a device,

It will receive VTP configurations and updates from the VTP server. Note: by default, the Catalyst 5000 series switches are VTP servers. Cat5002> (enable) Cat5002> set vtp domain cisco mode client T

In the complex network environment today, the switch has become indispensable, so the switch manufacturers also develop quickly, here to take Cisco to give us a simple exchange! Cisco: Cisco; A simple introduction: Cisco is the wo

The Cisco layer-3 switch is another core switch developed by Cisco. It aggregates the bandwidth of the backboard of the switch that is stacked together, in this way, the total backplane of the switch stack is the sum of the bandwi

ports are bound to an independent Logical Link. For example, you can bind a 4006 vswitch to a maximum of eight compatible ports with the same speed on any 4006 module. Each Ethernet channel has a port-channel port number. To bind an Ethernet channel, a logical port-channel is generated. The configuration under the logical port may affect the physical port bound with it, however, the configuration of physic
