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. Figure 2 lists the components of the layer-3 switch. The interface layer includes all important LAN interfaces: 10/100 Mbit/s Ethernet, gibit Ethernet, FDDI, and AT

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

destination site C, and the data forwarding process will all be handed over to the second layer for exchange processing, therefore, information is 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

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

be in different VLANs,If the controlled port is a VLAN, it includes the physical ports in the VLAN. If the Controlled Port is an Ethernet channel, it includesAll physical ports. If the controlled port 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

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

VLAN (virtual local area network), is based on the Ethernet interactive technology to build a fictitious network, can either divide the same physical network into multiple valn, can also cross the physical network barriers, users in different subnets to the same VLAN.

So, if you're sure what you're going to connect to, you can terminate the process.

additional personnel fees are incurred by sharing space with others, or supervising employees, these fees should be included in the downtime cost. As shown in the following example, channel replacement is a more important factor in the case of device replacement. The added maintenance costs have an important impact on the data center. Enhanced cat6 and category 7/class F channels are the most cost-effective. You can also add a trade-off factor in the last column: a specific standard, such as

Access Protocol) is the standard way to add XML information to an HTTP message. Tunneling (Web Tunnel): This way you can access applications that are not HTTP protocols through HTTP applications. The most common reason to use tunneling is to embed non-HTTP traffic in an HTTP connection so that traffic can pass through firewalls that allow only web traffic. Use connect to create an HTTP tunnel. Trunking (relay):
