36CHAPTER 3: RELEASE ISSUES

■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-port1000BASE-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.
