What is VTP v2 mode?

Description. This command places the device into VTP version 2 mode. All devices within a VTP domain must run the same version of VTP. You can simply configure this on one device (like the server VTP switch) and all devices will be reconfigured to version 2 via VTP, provided that all devices are v2-mode capable.

Which VTP version supports more than 1005 VLANs?

VTP versions 1 and 2 only supports VLANs 1 to 1005. If extended VLANs are configured, we cannot convert from VTP version 3 to version 1 or 2.

What are the VLAN Trunking Protocol VTP modes?

VTP modes – There are 3 modes:

• Server – The switches are set to this mode by default.
• Client – In this mode, the switches receives the updates and can also forward the updates to other switches(which are in same VTP domain).
• Transparent – This mode only forwards the VTP summary advertisements through trunk link.

Which VLAN number is never eligible for VTP pruning?

VLAN 1
VLAN 1 is never pruning eligible, because it is a factory-default VLAN. VLANs 1002 to 1005 are reserved for token ring networks. The VLANs 1006 and above require VTP version 3 to be pruning eligible.

What is the trunking protocol used?

The Dynamic Trunking Protocol (DTP) is a proprietary networking 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. It works on Layer 2 of the OSI model.

Which are the two trunking protocols?

Trunking Protocol Standards. There are two trunking protocols used on modern communication networks: Inter-Switch Link (ISL) from Cisco and the aforementioned nonproprietary IEEE 802.1Q. Of the two, IEEE 802.1Q is the industry standard. Even Cisco switches now use IEEE 802.1Q (dot1q) by default.

What is an isolated VLAN?

Isolated VLAN – is a secondary VLAN. It carries traffic from isolated ports to promiscuous ports. Only one isolated VLAN can be configured per private VLAN.

Do VTP versions have to match?

Within a management domain, the two versions are not interoperable. Therefore, the same VTP version must be configured on each switch in a domain. VTP version 1 is the default protocol on a switch.

What is the support for Token Ring VLANs with Cisco VTP V2?

The support for Token Ring VLANs is there with VTP V2. According to Cisco VTP V3 documentation, VLAN Trunking Protocol (VTP) Version 3 introduces the concept of transferring an opaque database in situations where VTP version 1 and VTP version 2 interacted with the VLAN process directly. VTP version 3 includes support for the MST mapping table.

What is VLAN Trunking Protocol (VTP)?

VLAN Trunk Protocol (VTP) is a protocol created by Cisco to create and manage VLANs for a large network with many interconnected switches and to maintain consistency throughout the network. In other words, switches use VLAN trunking protocol (VTP) to communicate among themselves about VLAN configuration.

What is Cisco VTP version 2 config?

VTP version 2 config (Cisco) VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol which allows to propagate VLAN database across Local Area Network (switching segment). VTP version 2 supports basic VLANs (2-1001) propagation, work with ISL protocol, supports authentication with MD5 hash.

What is the difference between VTP version 1 and VTP V2?

The functions of VTP Version 1 and VTP Version 2 are almost similar. The support for Token Ring VLANs is there with VTP V2.
