What is ctCDPInvalidVersionPackets?
This read-only Counter32 tallies CDP packets received with a protocol version not supported by this device. An administrator watches this counter to detect version incompatibility with neighboring devices, which would explain why some expected neighbors never appear in the CDP neighbor table. For example, if this counter steadily increments while a known-adjacent device never shows up as a CDP neighbor, the admin suspects that neighbor is running an unsupported, likely newer, CDP version.
