Symptoms

RAPID_PVST protocol is not supported but we allow its configuration. (config)# stp global config enabled-protocol RAPID_PVST (config)# commit

Impact

Configuration of RAPID_PVST is allowed, which is not supported. Note: In case of live upgrade, STP with global protocol configured as RAPID_PVST will not work and you will need to either delete "stp global config enabled-protocol RAPID_PVST" or do a bare metal install before performing a live upgrade.
