In BIG-IP Version 12.1.2 several F5 MIB variables changed from 64-bit counter types to 32-bit gauge types. This change was made to make the MIBs RFC compliant. In a mixed environment, where some BIG-IPs are running 11.x and some running 12.x this can cause problems with the management station. If the management station cannot load MIBs dependent upon BIG-IP version then those variables can cause errors to be reported on the management station due to type mismatch.
The management station reports errors due to type mismatch for some variables.
An environment where a management station is managing BIG-IP systems with a mix of version 11.x and 12.x. The station may import a MIB version whose types do not match the MIBs on the BIG-IP system with regards to the type changes made in version 12.x.
