1, Catalyst 35500XL/2950XL stack is how to achieve? A. Special tiered cabling is required, 1 m long or 50 cm long (cab-gs-1m or cab-gs-50cm) and a dedicated gigabit stacked card Gigastack GBIC (WS-X3550-XL) (which already contains cab-gs-50cm stacked cables). B. There are 2 stacking methods available: Daisy Chain (providing 1G of bandwidth) or point-to-point method (2G bandwidth available). C. 2 ways to do backups. D. Daisy chain method can support up to 9 switch stacks, point-to-point metho

For the connection between the switches, there should be more familiar two kinds: first, is stacked, two, is cascaded. The cascading approach is relatively easy to create bottlenecks between the switches, while stacking technology can increase the backplane rate, can eliminate the bottleneck of the connection between the switches, but by the limitations of distan

At present, layer-3 routing switches are widely used. Here we mainly introduce the differences between layer-3 routing switches and routing functions. As we mentioned earlier, layer-3 routing switches also have certain "routing" functions to achieve connections between different subnets. However, it should be noted that its routing function is much weaker than th

example. There are blades that support applications such as Veritas Volume Manager and ibm san volume controller SVC. These blades can coexist with other blades, including Fiber Channel ports and IP servers. Brocade 7420 multi-protocol router is another example of a switch with advanced intelligence. It was initially used to support protocol conversion from a small computer interface to a fiber channel ), segmentation and routing of SAN and IP-based Remote Storage Using FCIP protocol. Other vsw

Program-controlled switches are still commonly used. So I have studied the comprehensive Lightning Protection Problem of the program-controlled switches. Here I will share it with you and hope it will be useful to you. Power Communication (Power Communication Network) is an indispensable part of modern power systems and one of the three pillars of the safe and stable operation of modern power grids, the pro

As an inbound or outbound QoS site, edge switches play a very important role, especially in small and medium enterprises, if the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and Layer 3, therefore, the end-to-end smart network can be carried out on a large scale, so that the entire network not only has global

The core switch is still quite common. So I studied the Architecture Evolution of the core switch and shared it with you here. I hope it will be useful to you. Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key factor in the scope of application of devices. Different application environments require different network devices. For example, the applicat

Layer-3 switches and routers are widely used in various fields, including hub hubs. The most fundamental difference between a layer-3 Switch and a router is that a layer-3 Switch also has a "routing" function, which is consistent with the routing function of a traditional router. However, layer-3 switches and routers are quite essentially different. 1. Different Main Functions Both layer-3

Because the LAN contains a large number of computers and relies solely on anti-virus software to scan and kill one by one, the workload is huge. Therefore, it is necessary to have a good core switch. The following describes how to configure the core switch. in order to confirm that the failure of a vswitch is irrelevant to the working status of the Web server, this shows that the speed at which LAN workstations transmit files to each other is normal. In addition to some common faults, when encou

Core route switches are worth learning. Here we mainly introduce the mainstream core route switches in the market, RG-S7600 series of Core routing switch is the ruijie Network launched by the business as the core, for the next generation of network 10-Gigabit Backbone Routing Switch, provides large capacity, high density, modular architecture, based on the stable, reliable, and secure high-performance L2/L3

transmission is reduced, and the efficiency of the entire network is also improved! People have found that bridges are really a good thing. With the development of hardware, there are four link layer devices with eight ports. This is a switch, because vswitches can make the network more secure (data is not easily listened to, because data is no longer broadcast. Note: It's just not easy, but you can still do it ), higher network efficiency (or because data is no longer broadcast !),

[Experiment name]Configuring Telnet logins for routers/switches[Experimental purpose]Learn how to enable Telnet on the switch, enabling remote access to the switch via Telnet.[Background description]Enterprise Campus Network coverage is large, the switch will be placed in different locations, if each configuration switch to the location of the switch site configuration, the administrator's workload will be very large. The telnent configuration can be

Hubs, switches, and routers, which are known as network hardware, have always been active in the network field. However, many cainiao who are new to the network are annoyed by the fact that, they are not only similar in appearance, but also often stay together. It is a bit difficult to tell who they are! Let's take a look at the differences and relationships between them! 1. Hub 1. What is a hub? Before you know the hub, you must first understand the

The Cisco 4500 series with Huawei's 9300 series switches is positioned in the product line of the entire switch product. All belong to the enterprise core-level switch equipment, today the Cisco 4500 series and Huawei 9300 Series as an article, one is that these 2 products are currently in the enterprise application of a very wide range of equipment, whether it is a party (enterprise management) or party B (System integrators) are not unfamiliar. Seco

VC so Name think meaning is: virtual-chassis virtual chassis meaning. We need to understand why this is used? What is the benefit of using this method? We know that there are two VCP ports on the back of a switch, with 32Gbps backplane bandwidth per port, and if we connect the two ports to the VCP port of the other switch, is the bandwidth increased to 64Gbps. This is a clear benefit, the ability to process data and the forwarding state is more effective, and the advantage is that two units can

Outlook supports a number of command-line switches that modify the program starts and functions. Although you can issue the Outlook.exe command with switchesFrom a command prompt, it's generally more useful to specify switches through a shortcut,Particularly if want to use the same set of switches more than onceSome of the startup

1. High-capacity equipment The network traffic of data center has the characteristic of high density application dispatch, surge type burst buffer, and the common switch is to meet the interconnection and interworking as the main purpose, can not realize the accurate recognition and control of the business, can not do fast response and 0 lose package in the big business situation, cannot guarantee business continuity, The reliability of the system depends mainly on the reliability of the equipm
