What is VTP domain?
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.
What is the use of VTP domain?
VTP allows you to add, delete and rename VLANs which is then propagated to other switches in the VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks. There are some requirements for VTP to communicate VLAN information between switches.
What is VTP and DTP?
VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. DTP should not be confused with VTP, as they serve different purposes. VTP communicates VLAN existence information between switches. DTP aids with trunk port establishment.
What do you need to setup a VTP domain?
VTP configuration
- a switch has to be configured as either a VTP server or VTP client.
- the VTP domain name has to be the same on both switches.
- if present, the VTP domain password has to be the same.
- VTP versions have to match.
- the link between the switches has to be a trunk link. Consider the following example network:
How do I view VTP?
To see the VTP settings, use the show command. Passwords are listed with the password command. counters is a little less useful — unless you are not seeing any of the VLAN updates from neighboring switches. In that case, counters is very useful because it shows you the advertisements that you sent and received.
What is the best practice of VTP?
VTP Transparent mode
If VTP must be used, VTP Transparent mode is best practice because it decreases the potential for operational error.
What is VLAN Trunking Protocol (VTP) domain?
A VLAN Trunking Protocol (VTP) domain is one switch or several interconnected switches sharing the same VLAN Trunking Protocol (VTP) environment. A switch can be configured only in one VLAN Trunking Protocol (VTP) domain.
What is the function of a VTP server?
VTP sends messages between trunked switches to maintain VLANs on these switches in order to properly trunk. VTP is a Cisco proprietary method of managing VLANs between switches and runs across any type of trunking mechanism. VTP messages are exchanged between switches within a common VTP domain.
What is VTP in networking?
VLAN Trunking Protocol (VTP) is a Cisco network protocol that propagates the definition of Virtual Local Area Networks (VLAN) on the whole local area network.
What are the characteristics of the server VTP mode?
What are three characteristics of VTP? (Choose three.) In the default VTP mode, VLANs can be created and modified on a switch. Switches in VTP server mode store VLANs in the vlan.dat database. VTP-enabled switches exchange three types of advertisements: summary routes, subnet advertisements, and advertisement requests from transparent bridges.
