What Is a Trunk Link Overview Trunk links are physical links between switches or between switches and routers. The data frames transmitted on a trunk link must be tagged so that devices can identify the VLAN to which the data frames belong. Therefore, a trunk link can carry data frames of ...
When set up correctly, virtual LANs improve the performance of busy networks. VLANs can group client devices that communicate frequently with each other. The traffic among devices split across two or more physical networks is usually handled by a network's corerouters. With a VLAN, that traffic...
A VLAN ID is translated to a VLAN tag, a 12-bit field in the header data of every Ethernetframesent to that VLAN. Because a tag is 12 bits long, up to 4,096 VLANs can be defined per switching domain. VLAN tagging is defined by IEEE in the 802.1Q standard. When an Ethernet frame...
Atrunk portis a type of connection on a switch that is used to connect a guest virtual machine that is VLAN aware. Generally, all frames that flow through this port are VLAN tagged. The exception to this is when a trunk port is granted access to the untagged VLAN set (native VLAN ID)...
A VLAN trunk port is a networking port that is used to carry traffic for multiple VLANs (Virtual Local Area Networks) over a single physical connection. Trunk ports are often used to connect switches, routers, and other networking devices in a network, and are typically configured to allow ...
B. It designates VLAN 999 for untagged traffic. C. It blocks VLAN 999 traffic from passing on the trunk. D. It designates VLAN 999 as the default for all unknown tagged traffic. 相关知识点: 试题来源: 解析 B 正确答案:B解析:native vlan是不打标签的VLAN,这指定native vlan 为999,表明 ...
A layer 3 device (typically a Router) is used to segment (divide) a broadcast domain to multiple broadcast domains. By default, all ports on a switch are in the same broadcast domain. A Virtual Local Area Network, Virtual LAN, or VLAN, can be used to segment (divide) a single ...
Router-on-a-Stick Inter-VLAN Routing:This type of VLAN routing enables one single physical interface to achieve traffic forwarding between VLANs. After configuring the connection between the router and the VLAN switch as a trunk link, the router can receive frames with VLAN tags on the trunk ...
What Is VLAN? VLAN Definition What are the types of VLAN? How to manage and configure VLANs What are the advantages of VLAN? What are the differences between LAN and VLAN? VLAN Definition A virtual local area network (VLAN) is a virtualized connection that connects multiple devices and netwo...
Although VXLAN is an extension to VLAN, VXLAN is quite different from VLAN in terms of virtual tunnel establishment. Now let's take a look at what VXLAN packets actually look like. Figure 20-70VXLAN packet format (using the outer IPv4 header as an example) ...
