VLAN Trunking Protocol. VLAN Trunking Protocol ( VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks ( VLAN) on the whole local area network. [ 1] To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks.
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of VLANs on the whole local area network. VTP is available on most of the Cisco Catalyst Family products. The comparable IEEE standard in use by other manufacturers is GARP VLAN Registration Protocol (GVRP) or the more recent Multiple VLAN Registration ...
The Dynamic Trunking Protocol (DTP) is a proprietary link layer protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN -aware switches, and for negotiating the type of trunking encapsulation to be used. VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. [1]
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 most common and preferred method, IEEE 802.1Q, adds a tag to the Ethernet frame labeling it as belonging to a certain VLAN. Since 802.1Q is an open standard it can work with equipment from any vendor. Cisco also has a (now deprecated) proprietary trunking protocol called Inter-Switch Link which encapsulates the Ethernet frame with its own ...
Private VLAN. Private VLAN, also known as port isolation, is a technique in computer networking where a VLAN contains switch ports that are restricted such that they can only communicate with a given uplink. The restricted ports are called private ports. Each private VLAN typically contains many private ports, and a single uplink.
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 ...
