The default value, 2, enables external clocking. The new value, 1, enables internal

clocking.

Enter the following to display the new value:

get wfHssiEntry.wfHssiInternalClkTestMode.4.1

The Technician Interface displays

wfHssiEntry.wfHssiInternalClkTestMode.4.1 = 1

Be sure to enter the following to set the variable back to external clocking to use

the external clock source:

set wfHssiEntry.wfHssiInternalClkTestMode.4.1 2;commit

Responding to QENET Underﬂow Errors

Transmit underﬂow errors can occur when a QENET link module is connected to

a FRE module and all four ports are transmitting. This often occurs when non-

SNAP encapsulated frames received from an FDDI ring are routed out the

interface of a QENET. An example of such a frame is a Novell proprietary

encapsulated frame on FDDI.

The wfCSMACDUﬂoTx attribute in the wfCSMACDEntry MIB object shows the

number of transmit underﬂow errors. These errors result in other stations

detecting CRC errors.

Enter the following Technician Interface command for each of the four connectors

only if you are experiencing transmit underﬂow errors as described above:

set wfCSMACDEntry.wfCSMACDAlignmentMode.<slot no.>.<connector>

1;commit

Then save the conﬁguration with these changes to the conﬁguration ﬁle.

When you set the wfCSMACDAlignmentMode attribute to 1 (ALIGN_ALL), the

router realigns the nonoptimally aligned frames before transmitting them.

When you set the wfCSMACDAlignmentMode attribute to 3 (DISABLED), the

router transmits the nonoptimally aligned frames without realigning them ﬁrst.
