I have an issue while implementing MSTP state machine.

In 802.1q, it says

13.25.13 rcvdMstiMsg

TRUE for a given Port and MSTI if and only if rcvdMsg is FALSE for the CIST for that Port and rcvdMsg is TRUE for the MSTI for that Port.

802.1q says that there is no need to set rcvdmsg for MSTIs. So rcvdMstiMsg is always false. Due to this, Port Information Machine's SUPERIOR_DESIGNATED state is not entered. As a result role is not becoming master.

Wikipedia's page on MSTP since i had no idea what the original user was talking about. Some further information on the system this is running on and the topology would help – Journeyman Geek Feb 8 at 12:06
