Trunk Mode

I remember there is a question on the type of trunk mode and you have to select about 3 answers out of 5. I cant remember the question exactly. It's like a mix of on, desireable, forwarding, transparant, blocking.

However, to answer it correctly regardless of the exact questions, its important to know these.

The Trunk mode can be on,off,desirable,auto,nonegotiate

Understanding VTP Modes

You can configure a Catalyst 4000 family switch to operate in any one of these VTP modes:

Server—In VTP server mode, you can create, modify, and delete VLANs and specify other configuration parameters (such as VTP version and VTP pruning) for the entire VTP domain. VTP servers advertise their VLAN configuration to other network devices in the same VTP domain and synchronize their VLAN configuration with other network devices based on advertisements received over trunk links. VTP server is the default mode.

Client—VTP clients behave the same way as VTP servers, but you cannot create, change, or delete VLANs on a VTP client.

Transparent—VTP transparent network devices do not participate in VTP. A VTP transparent network device does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements. However, in VTP version 2, transparent network devices do forward VTP advertisements that they receive out their trunking LAN interfaces.








A VLAN can be created or modified on a switch in which of the following VTP modes? (Choose all that apply.)
Server
Access
Client
Transparent
Root

Regarding VTP configuration revision numbers, which of the following statements are true? (Choose all that apply.)
A transparent switch will always have a higher configuration revision number than any other switch on the network.
VTP configuration revision numbers are changed on a switch when a VLAN is created, deleted, or modified.
If a switch with a higher configuration revision number is added to an existing network with the same VTP domain name, it will have no effect on the VLANs on all the functioning switches.
VTP configuration revision numbers can be reset to 0 by changing the VTP to transparent mode and then back to server or client.
You can view a switch's current VTP configuration revision number by issuing the command show vtp status.

Choose the commands that force an IOS switch to perform trunking on a FastEthernet interface 0/12. (Choose the best answer.)
set trunk on
interface Fa0/12 trunk on
switchport mode trunk
interface Fa0/12 mode trunk
interface Fa0/12 then switchport mode trunk

Which of the following is the default mode for a Layer 2 port on an IOS switch?
switchport mode access
switchport mode dynamic auto
switchport mode nonegotiate
switchport mode dynamic desirable
switchport mode trunk

Which of the following commands you can use to see which VLAN a port is assigned to? (Choose all that apply.)
show interface trunk
show interface type slot/port
show vtp status
show interface status
show vlan brief
show interface type slot/port switchport
