Table 35. portLoopbackTest command field descriptions (continued)
Field
Description
state
The
current state of the port.
Possible values include
UP
(active),
DN
(inactive).
lm0-7 (8-port)
lm0-15 (16-port)
The frame counts of active ports. The display shows the number
of frames transmitted and received and low level interface counts
(LLI_errs).
Central memory
The central memory status.
Possible values include
OK
,
FAULTY
.
Total Diag Frames Tx
The total diagnostic frames transmitted (Tx) since the last
startup. This number usually corresponds to the total frames
received (Rx) but may differ because of failure modes.
Total Diag Frames Rx
The total diagnostic frames received (Rx) since the last startup.
This number usually corresponds to the total frames transmitted
(Tx) but may differ because of failure modes.
Related error messages:
DIAG-INIT, DIAG-PORTDIED, DIAG-XMIT,
DIAG-TIMEOUT, DIAG-ERRSTAT, DIAG-STATS, DIAG-DATA, DIAG-PORTABSENT.
portRegTest
Figure 56 shows the
portRegTest
command, which checks each register and static
memory that are located on the system board. Registers are set under firmware
control and control the hardware route selection and other internal hardware
functions.
Attention:
This command cannot be performed on an operational switch. Before
issuing the
portRegTest
command, disable the switch by using the
switchDisable
command. Disabling the switch halts all operation on the switch.
This test validates that all registers can be successfully accessed.
Related error messages:
DIAG-REGERR, DIAG-REGERR_UNRST,
DIAG-BUS_TIMEOUT.
ramTest
Figure 57 shows the
ramTest
command, which checks CPU RAM memory. This
test validates proper memory function.
Related error messages:
DIAG-MEMORY, DIAG-MEMSZ, DIAG-MEMNULL.
