quickly exchanged. Architecture of layer-3 Exchange Technology A layer-3 switch is also called a route switch. A layer-3 switch can be considered as a model. It involves the layer-2 and layer-3 of the ISO Reference Model. As a switch, it has the same attributes as the second layer, and combines the advantages of the second layer switch and the third layer router into a flexible solution, it can provide line rate performance at all levels, so it has certain routing performance.

There are many things worth learning about the exchange technology. Here we mainly introduce the Analysis and Application of the Third-layer exchange technology. The third-layer switch is also called a routing switch. The third-layer switch can be seen as a model, it involves the second and third layers of the ISO Reference Model. As a switch, it has the same attributes as the second layer, and combines the advantages of the second layer switch and the third layer router into a flexible solution

certain routing performance. This integration structure also introduces policy management attributes, which not only associate Layer 2 with Layer 3, it also provides prioritized communication traffic processing, security, and a variety of other flexible functions, such as dynamic deployment of trunking, VPN and Intranet. The interface layer includes all important LAN interfaces: 10/100 Mbit/s Ethernet, gibit Ethernet, FDDI, and ATM. The switching lay

Link AggregationThere are port aggregation and port bundling. The English name is porttrunking. The function isVswitchTo achieve load balancing. Avoid link congestion. Through configuration, You can bind two or four ports to forward data on specific ports to prevent packet loss when the forwarding rate of a single link is too low. Advantages of Trunking: The price is low, and the performance is close to that of Gigabit Ethernet. You do not need to reW

is a trunk port, all VLAN traffic on the trunk port will be monitored.You can also adjust the filter VLAN parameters to only monitor the data traffic of the VLAN specified in the filter VLAN. Destination Port -- the target port of the span SESSION (Monitoring Port-that is, the monitoring port)The monitoring port can only be a separate physical port. A monitoring port can only be used in one span session at the same time.The port does not participate in other layer-2 protocols, such as Layer 2 p

VLAN (Virtual Local area Network), which is built on the basis of Ethernet interaction technology, can divide the same physical network into multiple valn, or cross the physical network barrier, and divide users from different subnets into the same VLAN. Figure 2 is an example of a VLAN partition. Figure 2 There are many ways to implement VLANs, and there are generally two types of VLAN partitioning based on switching devices: L Switch-based port partitioning L Extended Ethernet frame format

switch between each floor is connected to the P580 through a Gigabit Optical Fiber. Therefore, VLAN division is based on direct port division on the P580, set the optical fiber port connected to the P334T switch to the trunk line, so that multiple VLANs can be defined on the Cajun P334T switch at the same time, finally, layer-3 routing protocol is configured on the P580 to implement communication between VLANs. Log on to P580 and enter the configuration mode to set the VLAN: 1. Create a VLAN: s

execution during the implementation of the project. If the contract is in conflict, the contractor should be urged to adjust the project schedule;12) Review the schedule of each sub-project stage prepared by the contractor, and supervise the contractor to adjust the schedule in time according to the changes in the actual environment;13) Review the engineering design and the contractor's equipment/materials list and procurement plan, and check and supervise its implementation.2, what is the core

computers can communicate, that is to say, from a functional and logical perspective, these computer networks have formed a large computer network, or the Internet, but also referred to as the Internet, interconnection network.Connecting networks to each other to use some intermediate devices (or intermediate systems), the term ISO is called a trunking (relay) system. Depending on the hierarchy of the trunking
