Security switches are worth learning a lot. Here we will mainly introduce how to set up a secure switch system. The IDS function of a security switch can be used for detection based on reported information and data stream content, when Detecting Network Security Events, perform targeted operations and send these actions to the vswitch. The vswitch can perform precise port disconnection. To achieve this kind of association, the switch must be able to s

VswitchThe high-end series isGuideGenerally, it refers to a vswitch at the pilot level. The guide is designed and built to achieve scalability and high availability. The term "pilot" was derived from the ibm escon pilot concept in the early 1990s s, the first version used for storage swap devices on large computers. In the early days, many vendors were able to provide FC directors. With the merger and acquisition, the FC directors market has been reduced to two major suppliers, brocade and Cisco

There are still prospects for the security deployment and upgrade of cisco switches. There may be no specific cisco switch security mode for the cisco switch Security description, so it may not help you, cisco switch security has become a new highlight in the switch market. Equipment redundancy is also important The physical cisco switch security, that is, the redundancy capability, ensures the safe operation of the network cisco switch. No manufactur

Layer-2, layer-3, and layer-4 switches have different characteristics. layer-2 switching is a mature technology. A layer-2 switch is a data link layer device that can identify MAC address information in data packets, forward based on the MAC address, and record these MAC addresses and corresponding ports in an internal address table. The specific workflow is as follows: (1) When the switch receives a packet from a port, it first reads the source MAC a

Layer-3 switches are commonly used. Here we mainly analyze the differences between layer-3 switches and routers. Here we will share with you, hoping to help you. In recent years, with the rapid development of Internet/Intranet and the wide application of the B/S computing model, the cross-region and cross-network business has experienced a sharp increase. The industry and users are deeply aware of the bottl

between VLANs and CIDR blocks. Multiple VLANs, QoS, bandwidth restrictions, and access control ensure smooth and clear VoIP calls and video conferencing. 　With standard 1-gigabit Ethernet ports on the front panel, you can easily stack up to eight 1-gigabit Network Management switches. This provides excellent scalability to meet your ever-growing network needs. As a member of the ProSafe Fast Ethernet three-layer stackable switch family, FSM7328PS ca

slows down significantly. Some access layer switches and some small routers even crash, and the CPU usage of the core layer-3 switch reaches 100%, the operator has to Block ICMP packets. Broadcast exception packets: broadcast is a necessary way to implement certain protocols. Broadcast packets are sent to all hosts in a specific network segment. Each host processes the received packets and makes a response or discard decision, the result is that both

storage technology has also evolved to NAS network storage. Even with the simplest DAS, the server's SCSI hard disk is a gigabit port on the storage end. Almost 100% of NAS storage devices provide Gigabit copper interfaces. The storage mode of the DAS structure plays a dominant role in the server, while 90% of servers provide Gigabit copper interfaces. There is no doubt that the use of a Gigabit Ethernet switch with a gigabit copper interface at the storage point has a great advantage, that is,

It's classic. I use it.DeploymentsThe deployments in this document were implemented in an isolated lab environment. the deployments were cleared by issuing the write erase command on the routers, and the clear config all command on the switches to ensure that all devices have a default configuration. make sure you understand the potential impact of any configuration or command on your network before using it.Catalyst 6500 SwitchNote: The following scr

capabilities of the console and command line interface, and support for Web, SNMP, and RMON. There are also important performance tests. We use the industry-renowned network performance tester IXIA 1600 in performance testing. IXIA 1600 can be inserted with a maximum of 16 modules. Our test environment includes 5 10/100 M Adaptive modules, each of which has 4 10/100 Base-TX ports and 6 10/100/BASE-T adaptive LM1000T modules, each module has 2 10/100/M RJ-45 ports; 5 GBIC modules, each with 2 10

subnets, the vro on the border is responsible for connecting to the upper-layer network. Dividing subnets can narrow the broadcast domain and reduce the impact of broadcast storms on the network. Each vro interface is connected to a subnet. broadcast packets cannot be broadcast by the vro. The subnets connected to different vro interfaces belong to different subnets. The subnet ranges are physically divided by the vro. For a vswitch, each port corresponds to a CIDR block. Because the subnet con

At present, the development of routers, switches and hubs is very rapid, and the technology is more standardized and mature. First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN. The switch, also known as the switch-type hub, works basically the same as the hub. However, there is a difference between the two in terms of performance: the hub uses the shared bandwidth method, while the switch

be abbreviated as Switch> enable. You can also use the TAB key to automatically complete the command, such as Switch> en. Press the TAB on the keyboard to automatically complete Switch> enable. The port operating mode of the vswitch can be divided into three types: Access, Multi, and Trunk. The trunk-mode port is used for switches and vswitches, vswitches and vrouters. Most of the ports are used for Cascade network devices. Therefore, they are also

have spent a lot of time on these security maintenance. In view of this situation, Shanghai Boda believes that the current network bottleneck of radio and television is the convergence layer equipment. The aging of the Convergence layer equipment leads to the bottleneck of the current radio/TV network. The convergence layer switch can achieve the following functions: the convergence layer must be a three-layer device, in this way, DHCP server functions can be deprecated to the aggregation layer

Differences among hubs, switches, routers, reconnections, gateways, and bridges 1. a hub, also known as a HUB, works on the first layer of the OSI Layer-7 structure and is a shared-bandwidth device, receives data broadcast. Generally, the LAN uses a Star Connection topology, and each workstation is connected to a hub. Because of the bandwidth sharing feature of the hub, the network utilization efficiency is extremely low. Generally, the hub is not use

Internet cafe access Optical Fiber provides a faster and more stable network environment for Internet cafes. To achieve the best performance and functions of the entire network, a perfect combination of various optical fiber network devices is also required. Fiber optic network devices in Internet cafes are routers and switches. Router Selection: when the internet cafe adopts the fiber-optic access method, you need to use a router that can connect t

Different switches can communicate with the same VLAN, but different VLANs cannot.
