5.9.4.3.6 .application.numberOfSwitchUnits
OID: .1.3.6.1.4.1.21035.41.2.6.0
Syntax: INTEGER32
Access: read-only
Description: The number of switch units within the device.
Note:
For .numberOfSwitchUnits "2" is returned independently whether the device is
equipped with one or two switch modules.
This value is used to determine the maximum index of the following table:
5.9.4.3.7 .application.switchUnitTable
"2" is returned for .numberOfSwitchUnits (please refer to chapter 5.9.4.3.6), thus a
corresponding number of entries per .switchUnitTable OID. With this table the
switching status of a switch unit (here: switch module) can be checked or can be
altered using .swPosition (chapter 5.9.4.3.7.4). Additionally, via .swMembers
(chapter 5.9.4.3.7.3) the assignment is stated which port of the .portTable is
member of the related switch unit (i.e. (logical) switch module).
5.9.4.3.7.1 .application.switchUnitTable.switchUnitEntry.swIndex
OID: .1.3.6.1.4.1.21035.41.2.7.1.1.x
Syntax: INTEGER32 (1..64)
Access: not-accessible
Description: A unique value for each table entry ranging between "1" and the
number of entries (defined by .numberOfSwitchUnits, please refer
to chapter 5.9.4.3.6).
5.9.4.3.7.2 .application.switchUnitTable.switchUnitEntry.swSize
OID: .1.3.6.1.4.1.21035.41.2.7.1.2.x
Syntax: INTEGER32
Access: read-only
Description: The size of the switch unit (here: switch module).
Since all switch modules installed in a DEV 1951 are (basically) 2:1
switches, "2" is returned.
