R3303-HP HSR6800 Routers Interface Command Reference

206
Parameters
cpos-number: CPOS interface number.
e3-number: Number of an E3 channel on the specified CPOS interface, in the range of 1 to 3.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Usage guidelines
Compared with the display controller cpos command, this command can display the error and alarm
information of lower-order paths and E3 frames.
Table 27 Possible error types displayed in the output
Field Description
OOF
Out of frame (OOF) errors, generated upon receipt of E3 indicating that error occurs
to the framing bit of the received E3/T3 frames.
LOS Loss of signal (LOS) errors, generated upon detection of loss of input signal.
LOF
Loss of frame (LOF) errors, generated when detected consecutive LOS errors exceed
the allowed threshold.
AIS
Alarm indication signal (AIS) alarms, including those generated by the local end
upon detection of severe alarms like LOS and those received from the upstream
device.
RAI
Remote alarm indication alarms, received from the downstream device detecting
alarms.
MS_AIS Multiplex section alarm indication signal.
FERR Framing bit errors.
LCV
Line coding violation counts. LCV occurs when line code violates HDB3 (E3) or B3ZS
(T3) coding rules.
PERR
Parity error event counts, available only for T3. They are generated when the P1 and
P2 bits in T3 frames are not identical.
FEBE Far-end block error counts, available only for T3.
HCS Header check sequence error counts, or CRC errors in HDLC frames.
Examples
# Display the state information of E3 channel 1 on interface CPOS 2/0/0.
<Sysname> display controller cpos 2/0/0 e3 1
Cpos2/0/0 current state: UP
