VLAN (Virtual Local Area Network, all known as virtual local area network), is logically physical the LAN into different logical subnet small, each is a separate logical subnet broadcast domain. Simply put, is to a large local area network physical (LAN) software on the switch are divided into several smaller virtual LAN (VLAN). Because the switch is through the principle of communication VLAN subnets through the division, smaller broadcast domains can be drawn, to avoid data collisions within a large physical LAN could have serious consequences, but also to avoid the broadcast storm generation.
because all subnets broadcast will be limited resulting in a small virtual LAN. When the LAN between the different VLAN communicate with each other, due to a different IP subnet segment is not as original as a large LAN to communicate directly, requiring routing to forward, then they need to increase the routing equipment - to achieve the routing .
three
VLAN switching and routing are twins, you will have a VLAN routing.
before in the absence of three switches, VLAN communication between the need to match the expensive work of traditional routers. In the enterprise network, communication between different VLAN subnets frequent occurrence, and routers are software-based routing operation,nike free running shoe, efficiency is not high already, and if the router to each packet on a route, that is, each route
put the three switches in the network communication technology and the second floor of the exchange said the three-layer routing, or forwarding technology together, and through the ASIC technology to achieve wire-speed switching, significantly improve the ability of device data packet forwarding, eliminates the forwarding bottleneck. At the same time divided by VLAN and efficient multicast control, flow management and access control policy and other functions effectively to ensure the full utilization of network resources, and ensure the application to meet the needs of various users. In the first three switches for routing the data stream, it will generate a MAC address and IP address mapping table, when the same data flow again through when the second floor directly under the exchange of mapping table, which is multiple exchange
with three switches, the division of enterprises to do VLAN subnet, the device is relatively economic to pay much more, the network data routing between VLAN forwarding performance more efficient.
VLAN deployment is now a better choice, that is by the three switches and VLAN functions to achieve the second floor to match the access switch. And with the production of three switches manufacturers more and more abundant market supply, so prices are high above the original three will soon switch to the civilian population,tory burch black flats, in particular,asics gel kayano 14, three Gigabit switches in the popularity of high-end market, prompting Fast three switches to the popularity of low-end market,asics kahana 3, and the price dropped to SMEs in general have the ability to an acceptable level. So here the subject of this paper further points out the Deployed in the network core layer exchange for SMEs is not just a new topic.
exchange of small businesses to deploy three-tier instance
two sections from the above we know that the division of an enterprise local area network VLAN subnets for the importance and necessity, and by supporting projects necessary VLAN is to deploy three switch. Switch the current three-tier market development, brand fold out, but the price is some high, such as the Fast three switches in general 8000-9000 yuan, but the individual low-cost or some, such as: D-LinkDES-3326SR Price 4000 element, which gives us less than 100 small businesses can deploy the same VLAN network efficiency and security.
this case we chose this very economical three switches, the core of the network deployment of a D-LinkDES-3326SR three switches, access layer by the number of units D-LinkDES-3226S Fast stackable Layer switches to serve as.
DES-3326SR is a stackable multilayer switches can route it in a chassis with integrated three-layer wire-speed switching and IP packet routing and quality of service QoS features. It provides 24 10/100Mbps ports, one for Fast Ethernet, Gigabit modules, stack expansion slot, 8.8Gbps switch fabric, 8KMAC address table, 2K routing table,nike running flats Successful incentive Quotations, 6.6Mpps three packet forwarding rate, 16MBRAM cache . Support for redundant backup power supplies can be stacked together through high-speed stacking cables up to 13 units can be stacked. 8 10/100Mbps ports to allow distributors to provide aggregate bandwidth.
through the network segment to support the IEEE 802.1QVLANTagging workstations can be grouped into different VLAN. The switch also supports GVRP, VLAN configuration information in order to be automatically released. Supports RIP-
subnet planning and network configuration
VLAN IP planning division should be combined to make a VLAN interface to IP is the corresponding sub-segment is the section of a department of the subnet, VLAN interface, IP is a sub-gateway. VLAN should be based on sectors, the same sector, the host IP to IP-based VLAN interfaces assigned to a subnet range, belong to the same VLAN. This will not only useful in security and network administrators more easily manage and monitor. (Note: The VLAN gateway in the client corresponding to the VLAN interface IP.)
In the program planning in the enterprise network VLAN subnets corresponding to the four four key sectors, I believe that this is the best small business general department structure,cheap nike air max 95 100 Sorry, namely:
VLAN10 - General administrative office;
VLAN20 - Sales;
VLAN30 - Finance Department;
VLAN40 - the data center network center.
by VLAN after the allocation for each VLAN a
VLAN10 - 192.168.10.1
VLAN20 - 192.168.20.1
VLAN30 - 192.168.30.1
VLAN40 - 192.168.40.1
VLAN and routing configuration
a, DES- 3326SR three-switch VLAN configuration process
1. to create VLAN
DES-3326SR # Config vlan default delete 1-24? delete the default port VLANdefault contains 1-24
DES-3326SR # Create vlan vlan10 tag 10? create a VLAN named vlan10, and mark the VID for the 10
DES-3326SR # Create vlan vlan20 tag 20? create a VLAN named vlan20, and mark the VID for the 20
DES-3326SR # Create vlan vlan30 tag 30? create a VLAN named vlan10, and mark the VID for the 30
DES-3326SR # Create vlan vlan40 tag 40? create a VLAN named vlan10, and mark the VID for the 40
2. Add Port to The VLAN
DES-3326SR # Config vlan vlan10 add untag 1-6? the port 1-6 to VLAN10
DES-3326SR # Config vlan vlan20 add untag 7-12? the port 7-12 to VLAN20
DES-3326SR # Config vlan vlan30 add untag 13-18? the port 13-18 to VLAN30
DES-3326SR # Config vlan vlan40 add untag 19-23? the port 19-23 to VLAN40
3. Create VLAN Interface IP
DES-3326SR # Create ipif if10 192.168.10.1/24 VLAN10 stateenabled?
consider the proposed creation interface if10 to the VLAN named VLAN10 subnet, and specify the interface IP for the 192.168.10.1/24. Created enabled to activate the interface.
the same method to set other interface IP:
DES-3326SR # Create ipif if20 192.168.20.1/24 VLAN20stateenabled
DES-3326SR # Create ipif if30 192.168.30.1/24 VLAN30stateenabled
DES-3326SR # Create ipif if40 192.168.40.1/24 VLAN40stateenabled
4.
when configuring the routing layer three switch function, if only a single three-layer switch,tory burch flip flops _ Dubai City of Gold, VLAN only need to configure the virtual interface on the line, not with routing protocol. Because a three-switch on the switch in the virtual interface will appear as a direct route, so no static routes or dynamic routing protocol configuration.
Second, DES-3226S Layer switch VLAN configuration process
1. to create VLAN
DES-3226S # Config vlan default delete 1-24? delete the default port included VLANdefault 1-24
DES-3226S # Create vlan vlan10 tag 10? create a VLAN named vlan10,acg nike shoes, and mark the VID for the 10
2. Add the port to the VLAN
DES-3226S # Config vlan vlan10 add untag 1 -24? the port 1-24 to VLAN10
Similarly, configure the other switches DES-3226S Layer. After the completion of each respective VLAN can be two-story three-DES-3326SR switches and the corresponding VLAN switch port connection.
3. Configuring other three-tier exchange
If there are other three switches, such as another DES-3326SR, separated by 24 connections. First, the two DES-3326SR 24-port configuration for the TRUNK.
DES-3326SR # Config vlan vlan10 add tag 24
DES-3326SR # Config vlan vlan20 add tag 24
DES-3326SR # Config vlan vlan30 add tag 24
DES-3326SR # Config vlan vlan40 add tag 24
DES-3326SR # Config vlan vlan50 add tag 24
two DES-3326SR 24-port belongs to all of the VLAN, tag tag
three, the second DES-3326SR configuration
DES -3326SR # Create vlan vlan10 tag 10
DES-3326SR # Create vlan vlan50 tag 50
DES-3326SR # Create ipif if20 192.168.10.2/24 VLAN10stateenabled
DES-3326SR # Create ipif if30 192.168.50.1 / 24 VLAN60stateenabled
questions, the second DES-3326SR VLAN50 and the first stage on the other VLAN can not communicate, the need to increase the routing:
DES-3326SR-1 # ip route-static 192.168.50.0 192.168.50.0/24 255.255.255.0 192.1168.10.2 intended to point to the next hop IP is 192.1168.10.2
DES-3326SR-2 # ip route-static 192.168.20.0 255.255.255.0 192.1168.10.1 intended to point to 192.168. 20.0/24 for the next hop IP 192.1168.10.1
DES-3326SR-2 # ip route-static 192.168.30.0 255.255.255.0 192.1168.10.1 intended to point to the next hop IP 192.168.30.0/24 to 192.1168. 10.1
DES-3326SR-2 # ip route-static 192.168.40.0 255.255.255.0 192.1168.10.1 intended to point to the next hop IP 192.168.40.0/24 to 192.1168.10.1
