The following requests return incorrect or incomplete values for the
9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module:
The value of entPhysicalClass that is returned for the instance of
the module itself (entPhysicalClass.4) is 13. The value should be 9,
which represents the value for the module.
The value of entPhysicalVendorType that is returned for the
instance of the module itself (entPhysicalVendorType.4) contains an
incorrect cb9000 description.
The value of entPhysicalDescr that is returned for the module does
not contain slot, subslot, and revision numbers as it should.
The 9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module
returns values for entPhysicalIndex and entLogicalIndex, but these
objects are listed in the MIB as non-accessible objects.
The following objects are not returned:
a3ComSysBridgePortTransmitBlockedDiscards
a3ComSysBridgePortReceiveAllPathFilteredFrames
a3ComSysBridgePortTransmitAllPathFilteredFrames
a3ComSysBridgePortReceiveMulticastPathFilteredFrames
a3ComSysBridgePortTransmitMulticastPathFilteredFrames
The module agent does not return the ipNetToMediaPhysAddress
MIB-II to the ipNetToMediaTable. Other objects in the
ipNetToMediaTable are properly returned.
If you reset the 9-port 1000BASE-SX Gigabit Ethernet Layer 2
Switching Module from the EME, you see MIB II Cold Start and Link
Up traps from the module, but you do not see a Link Down trap. The
normal
Link Up... Link Down... Link Up
sequence has probably
occurred and the module has reset, even though you did not see a
Link Down trap.
The object cb9000BackplaneConnectIfIndex lists backplane port
numbers in decreasing order for the 9-port 1000BASE-SX Gigabit
Ethernet Layer 2 Switching Module. For other CoreBuilder 9000
modules, the backplane port numbers are listed in increasing order.
