Alcatel-Lucent 7750 Configuration Manual page 351

Description This command allows the user to configure the transmit payload type value in byte 0 of the payload structure
identifier (PSI) of the OPU overhead.
Default
3 for 10GE-LAN/WAN or OC192 with OTU encapsulation; 5 for GFP framed 10GE-LAN with OTU
encapsulation.
Parameters
auto — Transmits the standard value in the payload type field.
value — Non-standard payload type value to transmit in the payload type field.
expected
Syntax expected auto-generated
expected bytes byte [byte...(up to 64 max)]
expected string identifier
expected use-rx
Context config>port>otu>pm-tti
Description This command allows the user to configure the expected RX trail trace identifier (TTI) for path monitoring
(PM) in the ODU 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 64 bytes. This trace should match the far-end port's PM
trace. When this trace does not match the received PM trace, the ODU-TIM alarm will be reported if
enabled.
Default
Blank (all zeros)
Parameters
auto-generated — Sets the default
string string — Sets the PM TTI 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 PM TTI 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.
use-rx — Copies the received pm-tti to the expected either as a string or a sequence of bytes depending on
the received pm-tti data.
mismatch-reaction
Syntax mismatch-reaction {squelch-rx}
no mismatch-reaction
Context config>port>otu>pm-tti
Description This command allows the user to configure the consequent action to a pm-tti mismatch.
The no form of the command reverts to the default.
Default
none, the received traffic is passed through.
Parameters
squelch-rx — The received traffic is blocked.
