so many connections is that it can easily lead to a single point of failure for the network. In general, large networks use multiple hubs (or other connected devices).Reference: http://book.51cto.com/art/200706/49411.htmStacked HubsA stacked hub is similar to a stand-alone hub. Physically, however, they are designed to be connected to other hubs and placed in a separate telecom cabinet; Logically, a stacked hub represents a large hub. ".". One of the great benefits of using a stacked hub is tha

Virtual Local Area Network

is mainly because the data must be routed through the router when it passes from one LAN to another: the router determines the destination address of the packet based on the corresponding information in the packet, and then chooses the appropriate path to forward it. second, users are naturally divided into different groups of users (broadcast domains) according to their physical connection. This partitioning method is not based on the common needs and bandwidth requirements of all users in the

Describes the categories of vswitches.

department-level switch is a switch for a department-level network. It is much smaller than the network scale that can be followed by the first two types. This type of switch can be fixed or module configuration. Generally, in addition to the common RJ-45 twisted pair interface, it also has an optical fiber interface. Department-level switches generally have out

This allows for port management and any full-duplex or half-duplex transmission mode to control traffic, with the network management function, you can configure, monitor, and test switches through the serial port of

groups, each user in the group is like a user in the same LAN (maybe the user in the protocol group is located on many switches rather than a switch). At the same time, users who are not in this group cannot access members of this group. In fact, VLAN members can be defined in four categories: 1. VLAN division by port VLAN division is based on the port of the Et

disadvantage is that any device can be easily broadcast and multicast, which will bring security risks, such as broadcast storms. In order to solve this problem (and, of course, this is not the reason), a virtual local area network is present. A virtual local area network is a set of logical devices and users that are not subject to physical location restrictions. Different virtual LANs do not communicate as they do in a local area network, even if they are actually in the same LAN. Therefore,

purchased together with other vswitches to form a complete storage solution. Entry-level switches provide limited port cascade capabilities. Users may encounter some manageability problems when using such low-end devices separately.

However, due to the low network transmission rate of the 10 Mbps ISA plug-in Nic and occupying a large amount of CPU resources, only applicable to LAN with low speed requirements. Therefore, we recommend that you use a 100 Mbps PCI plug-in or a 10 Mbps/Mbps adaptive Nic, Which is inexpensive and can be adapted to a large number of users, applications that require large amounts of data transmitted over the Inte
