MD5 Digest Checksum Mismatch On Trunk:

Four switches are getting MD5 digest checksum mismatch on trunk: Et1/0, etc .

Solution: Force an update. On SW1, create a dummy vlan # and remove it. This gonna cause a trigger update in a vtp network.  Or shut the trunk link down and bring it back up.

SW1#show vtp status

New Configuration Revision number will increment.

Now all 4 switches will sync VTP.

#show vtp status

#show vlan brief
