A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). [2][3] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network. Basically, a VLAN behaves like a virtual switch or network ...
IEEE 802.1Q. IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails.
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission. Multicasts may be filtered from the ...
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet. [1] The protocol is formally referred to by the IEEE as Station and Media Access Control ...
IEEE 802.1ad is an amendment to the IEEE 802.1Q-1998 networking standard which adds support for provider bridges. It was incorporated into the base 802.1Q standard in 2011. [1] The technique specified by the standard is known informally as stacked VLANs or QinQ. The original 802.1Q specification allows a single virtual local area network (VLAN ...
Ubiquiti product lines include UniFi, AmpliFi, EdgeMax, UISP, airMAX, airFiber, GigaBeam, and UFiber. The most common product line is UniFi which is focused on home, prosumer, business wired and wireless networking. EdgeMax is a product line dedicated to wired networking, containing only routers and switches. UISP, announced in 2020, is a range ...
TR-069. A DSL modem, which is type of customer-premises equipment. The WAN interface of this device, in this case the DSL port, could expose CWMP to the internet service provider. Technical Report 069 (TR-069) is a document by the Broadband Forum that specifies the CPE WAN Management Protocol (CWMP). CWMP is an application layer protocol for ...
