ibSmaSwPortStateChange
Module: SMA-MIB
OID (symbolic): SMA-MIB::ibSmaSwPortStateChange
OID (numeric): 1.3.6.1.3.117.3.1.2.9
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This object is set to 1 whenever the PortState component makes any of the following state changes in the link FSM:
Down-->Initialize, Initialize-->Down, Armed-->Down, or Active-->Down
Also, changes in PortState resulting from SubnSet IBA command do not change this bit. This object is set to 0 when the SMA writes a 1; writing a 0 is ignored.
What is ibSmaSwPortStateChange?
A latching flag that this switch sets to 1 whenever one of its ports transitions to the Down state (from Initialize, Armed, or Active); a management station clears it back to 0 after noting the transition, since writing 0 is the only way to reset it.
