netgear layer 2 switch

A three or four-day shift was added. Finally, the three-layer switch has been taken care of. The previous touch was a fool. (Huawei's technical support attitude is not very good), The configuration environment and configuration files are as follows: Environment, dual-WAN port routing access to ADSL, the next to the Huawei S3928p-si do core switches. The switch

I. Overview:On the forum, I saw someone asking how to prevent long-distance fiber lines from being eavesdropped or connected to other illegal switches. If they are the same, port security is used to prevent random access, log on to the rack to perform the test and record the test results. Forum question link: Workshop.Ii. Basic Ideas:A. assume that the vswitch is a layer-3 vswitch B. if the two switches are connected by a

Layer-3 egress connection to the internal port of the firewall It is recommended that layer-3 core switches use VLAN1 to connect to the firewall's internal port. The Intranet access to the Internet may be slow due to IP redirection !! The specific examples and solutions are as follows: The core of a certain Enterprise Network is 4506, And the access is basically 2950 series. The core is an X 4548 GB nbs p;

eth1.200 hw ether 00: 05: 5D: 61: 00: 31, ifup eth1 A complete VLAN (interface) is successfully added. This function is equivalent to executing vlan 200, ip address 192.168.200.1 255.255.0 on a layer-3 switch. Configurations on L2 Switches The configuration on the L2 Switch is the same as before. Take AVAYA P334 as an example: set vlan 200, set port vlan 200

Experimental background: As the size of the company continues to expand, the network department at the same time applied for two optical fiber, one of the 10M, the other one for 20M, due to bandwidth asymmetry, the requirements in the three-tier switch to do a strategic route to achieve 2:1 of the traffic allocation, followed by two lines to each other, so as to achieve a safe and reliable network transmis

information, high-speed network connection has become an essential prerequisite for the formation of campus network. 2. Diversity of information structure Campus network should meet the needs of different levels of application, can be divided into multimedia applications (Internet access, multi-media teaching, electronic library, video on demand, school sites, internal e-mail, etc.), information management (score statistics, file management, etc.)
