managed switch vs unmanaged switch

Symptom Mr. Gu, a website IT manager, was an old friend of ours who met each other three years ago at the Cisco Conference and shared their experiences with some netizens. He was originally the Director of the information center in a large state-owned enterprise, responsible for network planning, design, construction, management and maintenance. For a long time there was no such message, and the free mailbox became invalid. In addition, I lost contact after I changed my work. He was wondering ho

that we often hear the fiber switch (FC switch, also known as "Fibre Channel switch" and "san Switch"). Because it belongs to a new type of device and is too different from what we normally see and use Ethernet switches (mainly in the form of protocol support), many readers, even enterprise users who already use a SAN

the hardware or network management system software plus hardware to reflect the way. For example, a device vendor will hardware a set of management software into a switch and router, or put it on the backbone of other network systems, the device in this network can be called network management devices. Network management is not only the administration of networked devices, but also the monitoring and management of network data flow. Because the

based on the management function. Vswitches of different manufacturers have different support capabilities for VLANs, and the number of supported VLANs varies. Network management functions Through the network management function, you can use management software to manage and configure vswitches, such as Web browsers, Telnet, SNMP, and RMON. Generally, vswitch vendors provide management software or third-party management software to remotely manage vswitches. Generally, a layer-3

InfiniteSwitch4000 and SVA InfiniteSwitch5000 series switches should be well-configured fixed configuration switches, which can be applied to second-level switches or small and medium network trunk, and can be connected to backbone switches through the uplink port, or you can manage small and medium networks. Therefore, when selecting a vswitch, you should consider whether to purchase a chassis or a fixed configuration vswitch based on your needs and expenses. In general, the expansion and redu

This example includes setting up the security Policy edition to control the Web logged-on user through the source IP address. Hosted in the IDC Room network equipment, for the formation of server clusters, the construction of E-commerce system architecture. One of the network hardware devices is the switch. The current level of operation is a network-management switch. As for the brand, the mainstream is

The telecom service center has a network management workstation to manage all the network equipment, the Mail server, DHCP server

one AP. The reason is very simple. Even if the range is available, multiple APs are needed to distribute connections in case of a large number of connections. The idea is ideal and understandable. But I don't know. If the AP is put there, the enterprise's wireless network is equivalent to an electromagnetic network composed of dense radio signals, which is unhealthy and environmentally friendly. If we pay a little attention to it, enterprise users have long been in demand for wireless networks

configured and installed vswitches, the Console port, Telnet, and Web are used to configure and try vswitch management methods, link aggregation, VLAN, MAC address filtering, static Unicast address, port image, and other functions, we managed the vswitch using the network management software provided by various vendors. In addition, we also used a MIB Browser to view the MIB information of the Gigabit Switch
