vtpConfigDigestErrors
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vtpConfigDigestErrors
OID (numeric): 1.3.6.1.4.1.9.9.46.1.5.1.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The number of occurrences of configuration digest errors for this management domain. A configuration digest error occurs when a device receives a VTP advertisement for which:
- the advertisement's Configuration Revision Number is greater than the current locally-held value, and
- the advertisement's digest value computed by the receiving device does not match the checksum in the summary advertisement that was received earlier. This can happen, for example, if there is a mismatch in VTP passwords between the VTP devices.
What is vtpConfigDigestErrors?
This counter tracks the number of times a VLAN Trunking Protocol (VTP) configuration digest error has occurred on a switch in a management domain. A digest error happens when a switch receives a VTP update with a higher configuration revision number, but the computed checksum does not match the advertised value, indicating potential configuration corruption or security issues. Network operators monitor this to detect when VTP synchronization problems occur across their switch fabric.
