3 Troubleshooting Functional Failures During Operation
25
No. Port state Cause Action
see 3.9.2 Communication failures occurring when
SML is used [OS-L2A].

If any of the reasons described above do not
apply and you want to activate the port, make
sure the cable is connected to the target port, and
then use the
activate
operation command to
activate the target port.
4
test
A line test is being performed at
the port by the
test
interfaces
operation
command.
To resume the communication, use the
no test
interfaces
operation command to stop the line test,
and then use the
activate
operation command to
activate the target port.
5
fault
The port hardware at the target
port causes the failure. Based on the log entry for the target port displayed by
the
show logging
operation command, see Message
and Log Reference and take the action described in
Action .
6
init
The target port is being
initialized. Wait until the initialization is complete.
7
dis
The
shutdown
configuration
command is set.
Make sure the cable is connected to the target port,
and set the
no shutdown configuration command to
activate the target port.
3.4.2 Actions to be taken for 10BASE-T/100BASE-TX/1000BASE-T problems
If a 10BASE-T/100BASE-TX/1000BASE-T problem occurs, use the procedure below to
isolate the failure.
1. Viewing logged data
For details about the information in the operation log, see Message and Log
Reference .
2. Isolating the cause of the problem according to the failure analysis method
Isolate the cause of the problem according to the failure analysis method described
in the following table.
Table 3-7 Failure analysis method for 10BASE-T/100BASE-TX/1000BASE-T problems
No. Items to check Cause Action
1 Use the show
interfaces
operation
command to display the
failure statistics, and
check whether there is a
count for the item shown
below for the target line.
If there is a count, see the
Cause and Action
columns.

Link down
Line quality is
degraded. Check the cable type. For the cable types, see the
Hardware Instruction Manual .
If the Switch is set as follows, make sure that the pin
mapping is for MDI-X:

A fixed connection is set for the target port.

Auto-negotiation is enabled and the automatic MDIX
functionality is disabled for the target port.
Check the cable length. For the cable length, see the
Hardware Instruction Manual .
