In Ethernet networking, there is no specific field within the Ethernet frame that explicitly defines the "native VLAN." The concept of a native VLAN is important when dealing with trunk ports, which are used to carry traffic from multiple VLANs across a single link. Any untagged packet that ...
Community: A node attached to a port in a community secondary PVLAN may send to and receive packets from other ports in the same secondary PVLAN, as well as send to and receive packets from the promiscuous PVLAN. For more information, seeAbout vSphere Networking. Notes: Promiscuous PVLANs hav...
In VLAN aggregation, two concepts are involved, namely, super-VLAN and sub-VLAN. Super-VLAN: It is different from the common VLAN. In the super-VLAN, only Layer 3 interfaces are created and physical ports are not contained. The super-VLAN can be viewed as a logical Layer 3 concept. It...
Super VLAN: In a super VLAN that is different from a common VLAN, only Layer 3 interfaces are created, and physical ports are not contained. The super VLAN can be viewed as a logical Layer 3 concept. It is a collection of many sub VLANs. Sub VLAN: It is used to isolate broadcast ...
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. ...
Native virtual local area network: A concept used in the traditional system or devices that don’t support VLANs. This network serves as a common identifier on opposing ends of the trunk links to carry untagged traffic generated by a system or devices configured with the native VLAN via switch...
In the spine-leaf networking, leaf nodes function as VTEPs to establish VXLAN tunnels and each can be used as a Layer 3 VXLAN gateway (also a Layer 2 VXLAN gateway). Spine nodes are unaware of the VXLAN tunnels and only forward VXLAN packets between leaf nodes. In the following figure,...
Wireless networks also need the flexibility to collect more than two devices equipped with wireless communication and networking capability. In recent years, wireless network has been attracting a lot of attention due to wireless devices have enjoyed a tremendous rise in popularity. In order to ...
In modern networking environments, Virtual Local Area Networks (VLANs) have become an essential tool for segmenting and managing network traffic. But not all devices in a network may support VLANs, requiring a solution that enables compatibility with older equipment. This is where the concept of ...
Security over the air cannot be enforced as it can on a wire. Service set identifiers, orSSIDs, with different passwords are used where necessary, such as in guest networks. VLANs were developed early in the evolution of networking technology to limit broadcasts and prioritize traffic. They ...
