A VTP domain for a network is a set of all contiguously trunked switches with the matching VTP settings (domain name, password and VTP version). All switches in the same VTP domain share their VLAN information with each other, and a switch can participate in only one VTP management domain. Switches in different domains do not share VTP information.
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.
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 ...
A virtual trading point is a non-physical hub for trading in natural gas markets, for which "there is a virtual trading point (VTP) for each market area, representing all entry and exit points in that market area." [1]
This information may include the operating system version, hostname, every address (i.e. IP address) from all protocol(s) configured on the port where CDP frame is sent, the port identifier from which the announcement was sent, device type and model, duplex setting, VTP domain, native VLAN, power draw (for Power over Ethernet devices), and ...
If using version 1 and 2, the switch must be in VTP transparent mode. VTP v1 and 2 do not propagate private-VLAN configuration, so the administrator needs to configure it one by one. Limitations of Private VLANs
Venturi Transport Protocol (VTP) is a patented proprietary transport layer protocol that is designed to transparently replace TCP in order to overcome inefficiencies ...
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.
