What is mstpRootInformationRootPort?
This read-only string reports which local port this switch uses to reach the root of a specific MST instance, which can differ from the port used to reach the overall CIST root. An admin checks this per instance to confirm traffic for a given VLAN group is taking the intended physical path. For example, this reporting port 6 for instance 2's root while the CIST root at instance 0 is reached via port 5 shows the two paths genuinely diverge, spreading traffic across separate uplinks.
