TxOls Transmission of N_Port
OLS.
A transmitted N_Port OLS indicates that the switch went
into an Off-Line state—that is, although the switch is still
powered on, it is not operational because the upper level
needs recovery time before data can be transmitted or
received. Frequent OLS states indicate that the devices
were able to establish connection. Then, loose connection
long enough for protocol reset also fail. This should be an
infrequent event unless connections are being disrupted at
the protocol level.
TxParityErr Parity error on the switch
port.
Any Parity must be reported and corrected immediately.
This parity error has the following indications:
• The switch port is receiving Data over the internal bus
with invalid Parity.
• The internal hardware may have failed.
TxTagErr Bad tag. This is an indication that the switch port is receiving Data
over the internal bus with bad Tags. The Bad Tag can be
caused by incoming corrupted Frames, which is indicated
by an Invalid Tag marker. Much link Parity, a tag is associ-
ated to each word in the frame. An internal hardware error
of the Tag bits is highly unlikely but still possible. Look
for other ports with link problems that might cause Frames
to be forward with bad tag to another port.
