VLAN Implementation
Troubleshooting VTP
The following are some common things to check when troubleshooting problems with VTP:
n Make sure you are trunking between the switches. VTP is sent only over trunk links.
n Make sure the domain name matches on both switches. (The name is case sensitive.)
n If the switch is not updating its database, make sure it is not in transparent mode.
n If using passwords, make sure they all match. To remove a password, use no vtp password.
n If VLANs are missing, check the Revision number for a possible database overwrite. Also check the number of
VLANs in the domain. There might be too many VLANs for VTP to update properly.
