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 switch Security Lecture Hall: cracking the shock wave virus and the red code, understanding the basic virus principles, and providing a good awareness of cisco switch security. Simple security measures will also receive attention. In today's online world, security is crucial. As the Internet has brought huge bene

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You c

the ports of the corresponding vswitch as required in table 1. To verify our configuration, you can use the show vlan command in privileged mode to display the configuration you just made and check whether it is correct. The above describes the VLAN configuration of the Cisco Catalyst 1900 switch. The VLAN configuration methods of other switches are similar. Refer to the relevant

switch kernel becomes a bottleneck for performance implementation; the second is the cross-bus structure. It can establish direct point-to-point connections between ports, which is good for single-point transmission performance, but not suitable for multi-point transmission. The third is the hybrid cross-bus structure, this is a hybrid cross-bus implementation method. Its design idea is to divide an integrated cross-Bus Matrix into small cross matric

Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the port directly connected to

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

================================ The port role is the specified interface, but the status is discarded, no forwarding is provided. It turns out to be an rstp problem. Why is a specified interface discarded? The specified interface should be fowding. Suddenly, a friend prompts me that if the rstp interface is selected as the specified interface, the downstream confirmation is required to enter the forwarding status. The P/A mechanism requires the link between the two switches to be point-to-poin

Found that Cisco Catalyst Switch reboot is always in rommom mode, the system reboots when the Confreg command chooses the startup mode of 1 (starting from the first file) and cannot enter the normal interface. Enter to boot: 0 = Disable Autoboot 1 = the internal flash device 2 = commands specified in ' BOOT ' environment variable [2]: 1 The analysis suggested that the iOS file might be corrupted or pu

Batch Processing directly logs on to the cisco switch and executes commands. In many cases, we may log on to the cisco switch to execute some common viewing commands. However, every time we run cmd, enter the password, and enter the command, it is troublesome. It can be achieved through batch processing. For example, i

With the development of China's routing industry, we have also promoted the update and upgrade of the routing switch technology. Here we have introduced the IOS restoration method of the Cisco routing switch, and we have tried one method, after Flash is deleted, the system cannot be started. You can use X-Modem to restore it. At that time, I accidentally deleted

relay mode on the port connecting a switch to a vswitch or connecting a vswitch to a vro, this enables data frames belonging to different VLANs to be transmitted through this relay link. The frame format of VLAN relay is divided into two types: ISL (Inter-Switch Link, connection between switches) and 802.1Q. The former is the protocol unique to the Cisco

Pen name is also large, the motto of the gameToday it is the command of the Cisco switch which is the practice of the work operation, I feel that sometimes it may be necessary to trace the port of which the MAC address belongs to the switching device, and to determine the object quickly, I share my exercise to the lovers who need it.The first thing you need to know is the IP address and account password of
