Configure, verify, and troubleshoot VTP and Configure, verify, and troubleshoot trunking on Cisco switches

The following is related to Configure, verify, and troubleshoot VTP and Configure, verify, and troubleshoot trunking on Cisco switches -

Configure switchport to be in a VTP domain named CCNA-LAB:

CCNA-SWITCH-LAB1(config)#int range f0/1-2
CCNA-SWITCH-LAB1(config-if-range)#switchport trunk encapsulation isl
CCNA-SWITCH-LAB1(config-if-range)#switchport mode trunk

You carry out this command on both switches. You can verify your config by issuing the show int trunk command and see whether the ports trunks are established.

Next you would set thee trunk name:
CCNA-SWITCH-LAB1(config)# vtp domain CCNA-LAB

The legacy option would be to enter into the vlan database for example:
CCNA-SWITCH-LAB1#vlan database
CCNA-SWITCH-LAB1(vlan)#vtp domain CCNA-LAB
CCNA-SWITCH-LAB1(vlan)# exit

It is important to type 'exit' or 'apply' to allow for the changes to take effect.

Next, you can verify the vtp status by typing

show vtp status.
