Overview of LAN switches LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch

CISCO mds FC optical fiber switch configuration reference(1) There are several concepts that must be clarified (different from brocade ):(1) brocade divides zones directly. While mds divides zones under vsan, mds can divide several vsan first, and each vsan includes several zones.(2) brocase: the default port is open, while the default port of mds is closed.(3) mds has a Default zone: "The Default Zone ". i

Cisco network Device interface is mainly divided into the following modes:1. Switchport mode access: Forces the interface to become an access interface and can actively negotiate with the other person to entice the other person into Access mode.2, Switchport mode dynamic desirable: active and to negotiate the possibility of becoming trunk interface, if the Neighbor interface mode is one of Trunk/desirable/auto, then the interface will become the trun

, and the slot number is different) Iii. Stack instances: 1: The stacked cables are physically connected. The connection method is master stack1, which is connected to slave stack2. 2: enable the master without any configuration. . 3: Server Load balancer is enabled. 4: No configuration is required. Line plug, automatic stacking election upon startup, master is highlighted) Note: You can also configure stacks first, such as IP addresses and priorities

want to initialize the switch, you need to enter the Privileged EXEC mode. Enter setup in the command prompt symbol to start the initialization operation.The Privileged EXEC mode is introduced just now. In this case, we need to talk about several modes of machine change. Different modes can execute different operation commands. First, we need to talk about two basic modes.For the sake of security, CISCO di

One outlet had poor contact. Because there was no wiring module, I just fixed the wiring block and the network was ready for use. After a week, the network was broken again and I asked another colleague to change the wiring module, as a result, my colleague told me that changing the wiring module would not work, and the network would still be disconnected. I thought it was strange. I told him that the Network was originally accessible, but the wiring module was not good. I will remove the wiring
