Interfaces
psi-tti
Syntax psi-tti
Context config>port>otu
Description
This command enables the context to configure payload structure identifier trail trace identifier parameters.
tx
Syntax tx {string identifier | bytes byte-sequence | auto-generated}
Context config>port>otu>psi-trace
Description
This command allows the user to configure the transmit trace in bytes 1 to 255 (skipping byte 0) of the pay-
load structure identifier (PSI) of the OPU overhead. This identifier can be a string or a non-printable
sequence of bytes. The length of the string or sequence of bytes cannot exceed 255 bytes.
Default Blank (all zeros)
Parameters auto-generated — Sets the default PSI trace
string identifier — Sets the PSI trace to the string provided by the user. If the string is less than 255 bytes,
the remaining bytes will be set to 0.
bytes byte1 [byte2...(up to 64 bytes)] — Sets the PSI trace to the sequence of bytes provided by the user. If
the user provides less than 64 bytes, the remaining bytes will be set to 0. A 1 byte sequence of 0xFF will
set the default strings.
Values
expected
Syntax expected {string string | bytes byte-sequence | auto-generated | use-rx}
Context config>port>otu>pm-tti
Description
This command allows the user to configure the expected RX in bytes 1 to 255 (skipping byte 0) of the Pay-
load structure identifier (PSI) of the OPU overhead. This identifier can be a string or a non-printable
sequence of bytes. The length of the string or sequence of bytes cannot exceed 255 bytes. This trace should
match the far-end port's PSI trace. When this trace does not match the received PSI trace, the OPU-TIM
alarm will be reported if enabled.
Default Blank (all zeros)
Parameters auto-generated — Sets the default
string string — Sets the PSI trace to the string provided by the user. If the string is less than 64 bytes, the
remaining bytes will be set to 0.
bytes — [byte1 byte2 ... byte64]. Sets the PSI trace to the sequence of bytes provided by the user. If the user
