  2. VLAN Trunking Protocol - Wikipedia

    en.wikipedia.org/wiki/VLAN_Trunking_Protocol

    VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks 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 ...

  4. Trunking - Wikipedia

    en.wikipedia.org/wiki/Trunking

    Trunking in telecommunication originated in telegraphy, and later in telephone systems where a trunk line is a communications channel between telephone exchanges. Other applications include the trunked radio systems commonly used by police agencies. [1] In the form of link aggregation and VLAN tagging, trunking has been applied in computer ...

  5. IEEE 802.1Q - Wikipedia

    en.wikipedia.org/wiki/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.

  7. VLAN hopping - Wikipedia

    en.wikipedia.org/wiki/VLAN_hopping

    In a double tagging attack, an attacker connected to an 802.1Q-enabled port prepends two VLAN tags to a frame that it transmits. The frame (externally tagged with VLAN ID that the attacker's port is really a member of) is forwarded without the first tag because it is the native VLAN of a trunk interface.

    He too eventually pleaded guilty, in 2019, after an undercover agent busted him selling weapons out of the trunk of his car. His stockpile at the time totaled more than 250 firearms, including 41 ...

  9. Dynamic Trunking Protocol - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Trunking_Protocol

    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]
