Adding A Vtp Client Switch To A Vtp Domain - Cisco 3032 Software Configuration Manual

Chapter 14 Configuring VTP

Adding a VTP Client Switch to a VTP Domain

Before adding a VTP client to a VTP domain, always verify that its VTP configuration revision number
is lower than the configuration revision number of the other switches in the VTP domain. Switches in a
VTP domain always use the VLAN configuration of the switch with the highest VTP configuration
revision number. With VTP versions 1 and 2, adding a switch that has a revision number higher than the
revision number in the VTP domain can erase all VLAN information from the VTP server and VTP
domain. With VTP version 3, the VLAN information is not erased.
Beginning in privileged EXEC mode, follow these steps to verify and reset the VTP configuration
revision number on a switch before adding it to a VTP domain:
Command
Step 1 show vtp status
Step 2 configure terminal
Step 3 vtp domain domain-name
Step 4
end
Step 5
show vtp status
Step 6 configure terminal
Step 7 vtp domain domain-name
Step 8 end
Step 9 show vtp status
After resetting the configuration revision number, add the switch to the VTP domain.
Note You can use the vtp mode transparent global configuration command to disable VTP on the switch and
then to change its VLAN information without affecting the other switches in the VTP domain.
OL-12247-04
Purpose
Check the VTP configuration revision number.
If the number is 0, add the switch to the VTP domain.
If the number is greater than 0, follow these steps:
a. Write down the domain name.
b. Write down the configuration revision number.
Continue with the next steps to reset the switch configuration revision number.
c.
Enter global configuration mode.
Change the domain name from the original one displayed in Step 1 to a new name.
The VLAN information on the switch is updated and the configuration revision
number is reset to 0. You return to privileged EXEC mode.
Verify that the configuration revision number has been reset to 0.
Enter global configuration mode.
Enter the original domain name on the switch.
The VLAN information on the switch is updated, and you return to privileged EXEC
mode.
(Optional) Verify that the domain name is the same as in Step 1 and that the
configuration revision number is 0.
