5.1.2 Configuring VLAN Context VLAN is short for Virtual Local Area Network. Pay attention to the difference between VLAN and VPN (short for Virtual Private Network). VLAN means that devices of a local network are logically divided into several network segments to implement data switching between virtual work groups. In other words, the devices are not divided physically, work stations in the same VLAN are not restricted to be in the same physical range, and they can be located in different physical network segments of the local network. This new technology is applied in switches and routers, and the mainstream application of it is in switches. Only switches of the third layer (or higher) of the VLAN protocol have this function. l In the switching network, the broadcast domain can be a virtual network segment consisting of a group of layer-2 network addresses (MAC addresses) randomly selected. In this way, work groups in the network are divided according to the management functions, and are not restricted by the geographical locations. The work-flow-based group mode greatly improves network planning and network reorganization. l For work stations in the same VLAN, no matter which switch they are actually connected, the communication among them seems as if it is implemented through an independent switch. Broadcast within a VLAN can only be heard by the members of 5-2 SSJ-20110704155716-005|2011–07–30 (R1.0)

the VLAN, and will not be transmitted to other VLANs. It helps control the broadcast storm. Meanwhile, if there is no route between two VLANs, the communication between them will fail. It helps enhance the security between different departments in the enterprise network.

Note: At present, the information of port type, VLAN ID, and PVID are issued separately. Set Port Type to Access: The port can be configured with only one VLAN. The frame entering the Access port must be a frame having no label, labeled with PVID of the port, or VLANID as 0. The frame going out of the Access port must be a frame not having label. Set Port Type to Trunk: The port can be configured with multiple VLANs. The frame entering the Trunk port must be a labeled frame and the label is in the VLAN of the port. The frame going out of the Trunk port must be a labeled frame. Set Port Type to Hybrid: The Hybrid port receive frames of the following types: having no VLAN label, having a VLAN label contained in the VLANID of the port, having a VLAN label as 0. The Egress Policy of the Hybrid port has two types: UnModify and UnTag PVID. UnModify means not making modification, and the frame can be labeled or not labeled. UnTag PVID differs from UnModify in that when VLAN ID of the frame is same as PVID of the port, the label will be removed.
4. There are many ways to add/delete VLAN, as shown in Figure 5-7. Figure 5-7 Adding/Deleting VLAN
Add: Add VLAN within the specified range. Add all: Add all the 4094 VLANs. Add all except: Add VLANs except the specified VLAN. The specified VLANs are removed. Remove: Delete VLANs within the specified range. Remove All: Delete all VLANs. 5-5 SSJ-20110704155716-005|2011–07–30 (R1.0)

5.1.3 Configuring Trunk Context The trunk function of Ethernet port is also called port binding, port convergence, link binding, or link convergence. It converges multiple ports, which encapsulate the same link-layer protocol, to form a convergence group and implements outgoing/incoming load sharing at the ports of all members. Link convergence provides higher connection reliability. When a link is disconnected, the flow will be reallocated automatically among the remaining links. The trunk function is implemented dynamically or statically. The dynamic solution is implemented through the IEEE802.3ad LACP protocol. The static solution is implemented through manually configuring Trunk by the manager. To make the link convergence port implement the trunk function: l
l
Physical parameters at the two ends of the convergence port must be consistent. Such parameters include duplex mode, port learning status, port type (electrical/optical port), and port rate. Logical parameters at the two sides of the convergence port must be consistent. Such parameters include VLAN, QoS, and RSTP of the port.

5.1.5 Configuring FC and Rate Context Flow Control (FC) is used to prevent data packet loss when the port is blocked. It is implemented by sending the blocked signal to the source address when the sending buffer or receiving buffer overflows. FC effectively prevents the impact on the network due to the transient large amount of data and ensures a highly efficient and stable running of the network service. FC is implemented through the following two methods: l
l
In the half-duplex mode, FC is implemented by backpressure, namely, backpressure counter. This counter helps the information source decrease the transmitting rate by sending the jamming signal to the transmitting source. In the duplex mode, FC follows the IEEE 802.3X standard, and the switch sends the "pause" frame to the information source to ask it to stop sending data.
Steps 1. In the left navigation tree, choose Configure > ETH Traffic > FC & Rate. The Flow Control and Rate configuration interface is displayed, as shown in Figure 5-11. Figure 5-11 Configuring FC & Rate (1)
