layer 2 network switch

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

The h3c layer-3 Switch acl is an example of a new library that can only access the electronic reading room, and cannot access other hosts on the Intranet, so as to avoid security impact. the IP address of the On-Internet www.2cto.com electronic reading room is not opened to 10.0.1.9, the new library plans to divide vlan 11, network segment 10.1.11.0/25, and vlan-

[Background description] The company has an internal DI-604LB + Broadband Router and a layer-3 switch. To prevent broadcast storms in the network, the Administrator has created three VLANs on the layer-3 switch. The company uses DI-604LB + Broadband Router Access to the Inte

with the concept of session hijacking, it was still 2, that was 2001 ~ 2002. At that time, hubs were still quite common ). Another serious problem is that if a large local area network, such as 500 machines, is connected to all the HUB machines, what will happen ?? Very slow, with poor network efficiency! Why? If 500 machines send a packet, each machine needs to

The instance explains VLAN division and configuration issues in layer-3 Switch configurations. vlan division and configuration issues cannot be avoided in layer-3 Switch configurations. Generally, there are four categories, how to retrieve it becomes a concern. This article explains how to set VLANs in depth from the p

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

How to use a vro to connect different VLANs of a single-layer switch Some simple configurations of the experiment First configure PC PC1 IP: 192.168.1.1 subnet mask: 255.255.255.0 Gateway: 192.168.1.254 PC2 IP: 192.168.1.2 subnet mask: 255.255.255.0 Gateway: 192.168.1.254 PC3 IP: 192.168.2.1 subnet mask: 255.255.255.0 Gateway: 192.168.2.254 PC4 IP: 192.168.2.2 subnet mask: 255.255.255.0 Gateway: 192.168.2.2

First, network description The PC1 is connected to the Cisco3550 F0/1 and the rate is 100M; CISCO3550 's G0/1 for export. Second, the detailed configuration process Note: This configuration: Improve the reprint of some of the incorrect configuration. Each interface supports only one policy in each direction, and one policy can be used for multiple interfaces. Therefore, the download rate limit for all PCs should be defined in the same policy (in

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

2 here) only processes the protocol of the data link layer, while both the router and host process the IP. The switch does not process the IP address or the header of the network layer. When the package is sent down, every ptotocol must add the information that you communic

command menu interface. The biggest feature of annett AT-8024 is the unique "Enhanced Stacking" technology to stack up to 24 AT-8024 switches, in addition, it can be combined with switches in the AT-8000 series to expand the network scale. Annett AT-8024 also provides a wide range of functions. It supports VLAN, broadcast storm control, and packet header blocking (HOL) prevention mechanisms. It also supports various authentication functions, this all

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

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for

In Photoshop, I drag multiple images onto a background, a lot of layers to switch in the layer panel to find the blurred, I remember before there can be directly on the map to switch to the current layer of the function, but I installed the PS after I forgot how to set up. I am photoshop CS2, thank you. What are you t

Layer-3 Switch ACLs are used to isolate different VLANs.
