Good morning. We are having trouble getting VTP to update on one switch. To date I have tried the following:
- Confirmed that the domain name was consistent.
- Even changed the name and changed it back
- Confirmed that VTP passwords are not the problem.
- Added a new VLAN to prompt an update, it updated other switches but not this one.
- Confirmed that the trunking is set up the same as other switches.
- Changed the VTP mode from client to transparent and back.
Slightly redacted information from the switches below:
