I have configured redundant network using two Cisco SG300-28MP 28-port Gigabit Max-PoE Managed Switch through MSTP & it's working fine.
I need OID of MSTP status from which I can monitor which Switch is active and which one is in standby mode.
I downloaded MIB file from the below link http://www.cisco.com/c/en/us/support/switches/sg300-28mp-28-port-gigabit-max-poe-managed-switch/model.html#~rdtab1
But MIB browser throws an error saying "OID cannot be resolved through loaded MIB modules". Attached is the error snapshot for reference.
