Known Problems 37

■The object a3ComSysBridgePortAddressStaticPort should return one of the following values:

■The local bridge port index when a static address is configured for the port

■The value 0 when a dynamic address is configured for the port

However, the 9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module returns the following reversed values:

■The local bridge port index when a dynamic address is configured for the port

■The value 0 when a static address is configured for the port

■If there is a trunk on the switching module, an SNMP getnext request on the MIB object a3ComTrunkTcmpMacState incorrectly returns the first instance of this object. For example, a Gigabit Ethernet switching module that is located in slot 6 has two trunks:

■Ports 1 and 9 — MIB objects a3ComTrunkTcmpMacState.14.1 and 3ComTrunkTcmpMacState.14.9

■Ports 4 and 5 — MIB objects a3ComTrunkTcmpMacState.15.4 and 3ComTrunkTcmpMacState.15.5

■The objects in the a3ComTrunkMacTable are not accessible via SNMP.

■Through SNMP the object a3ComSysEthernetPortRequestedPortMode can be set to values out of range for the port, only use the values that are for 10 or 100. (30022)

Ethernet ■ The following Ethernet statistics are not reset after you enter the module baseline set command:

■rxPeakFrameRate

■txPeakFrameRate

■rxPeakByteRate

■txPeakByteRate

■If a bridging loop exists on a switching module or switch fabric module, output from the ethernet detail command can take up to 30 minutes to display. This issue does not apply to the 36-port 10/100BASE-TX Desktop Switching Modules (Model Numbers 3CB9LF36RL and 3CB9LF36TL). (30080)
