What protocol is used for trunking?
802.1Q and ISL are used to configure trunking on a port.
What protocol is used in VLAN trunk?
VTP
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. 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.
What does the VLAN Trunking Protocol VTP do?
Virtual local area network (VLAN) trunking Protocol or VTP is a proprietary protocol from Cisco that allows networks to send network functionality through all of the switches in a domain. This technique eliminates the need for multiple configurations for VLANs throughout the system.
What is VTP and why is is used?
VTP is a protocol used to distribute and synchronize identifying information about VLANs configured throughout a switched network. VTP enables switched network solutions to scale to large sizes by reducing the network’s manual configuration needs.
What are the 4 modes for DTP?
Dynamic Trunking Protocol (DTP)
- Dynamic Trunking Protocol –
- switchport mode access (DTP mode OFF) –
- switchport mode trunk (DTP mode ON) –
- switchport mode dynamic auto –
- switchport mode dynamic desirable –
- switchport nonegotiate –
What is the difference between VTP and DTP?
VTP and DTP are two different things. In summary, VTP is a protocol used to share VLAN information within a domain among connected switches. On the other hand, DTP is a protocol used to negotiate trunking between switch ports on either ends of a link.
What are different VTP modes?
VLAN Trunking Protocol (VTP) Modes, Server Mode, Client Mode, Transparent Mode. A network switch, which is participating in VLAN Trunking Protocol (VTP), can have three different modes.
What is difference between VLAN access and trunk mode?
The trunk port supports only the tagged frames, whereas the Access port sends and receives untagged frames. The trunk port allows us to switch multiple VLANs, but all frames are in the same VLAN in the Access port.
What is trunking in networking?
Networking. Trunking, a term frequently used in IT and telecommunications, refers to a network configuration that efficiently conveys data between multiple entities without using one-to-one links.
How do you negotiate trunking?
Enabling Trunking
- Enable the trunk: COS. set trunk mod/port [auto | desirable | on | nonegotiate | off] IOS. (global) interface type mod/port.
- Specify the encapsulation method: COS. set trunk mod/port [negotiate | isl | dot1Q] IOS.
- (Optional) Specify the native VLAN: COS. set vlan number mod/port. IOS.
