Number of configuration
digest errors
Number of MD5 digest errors.
Digest errors increment whenever the MD5 digest in the summary packet
and the MD5 digest of the received advertisement calculated by the
switch do not match. This error usually means that the VTP password in
the two switches is different. To solve this problem, make sure the VTP
password on all switches is the same.
These errors mean that the switch is filtering incoming advertisements,
which causes the VTP database to become unsynchronized across the
network.
Number of V1 summary
errors
Number of Version 1 errors.
Version 1 summary errors increment whenever a switch in VTP V2 mode
receives a VTP Version 1 frame. These errors mean that at least one
neighboring switch is either running VTP Version 1 or VTP Version 2
with V2-mode disabled. To solve this problem, change the configuration
of the switches in VTP V2-mode to disabled.
Join Transmitted Number of VTP pruning messages sent on the trunk.
Join Received Number of VTP pruning messages received on the trunk.
Summary Advts Received
from non-pruning-capable

that do not support pruning.
