timestamp and identity, the authentication checksum, and the
number of subset advertisements to follow.

trunk ports. Advertisement requests normally request information
on all VLANs. They can also request information on a subset of
VLANs.

ports. Summary advertisements contain the management domain
name, the configuration revision number, the update timestamp and
identity, the authentication checksum, and the number of subset

Number of revision errors.
Whenever you define a new VLAN, delete an existing one, suspend
or resume an existing VLAN, or modify the parameters on an
existing VLAN, the configuration revision number of the switch
increments.
Revision errors increment whenever the switch receives an
advertisement whose revision number matches the revision number
of the switch, but the MD5 digest values do not match. This error
means that the VTP password in the two switches is different or that
the switches have different configurations.
These errors means that the switch is filtering incoming
advertisements, which causes the VTP database to become
unsynchronized across the network.
