psi-payload
Syntax psi-payload
Context config>port>otu
Description This command enables the context to configure payload structure identifier payload parameters.
expected
Syntax expected {value | auto}
Context config>port>otu>psi-payload
Description This command allows the user to configure the expected received payload type value in byte 0 of the
Payload structure identifier (PSI) of the OPU overhead. When this values does not match the received
value, the OPU-PLM alarm will be reported if it is enabled.
Default 3 for 10GE-LAN/WAN or OC192 with OTU encapsulation; 5 for GFP framed 10GE-LAN with OTU
encapsulation.
Parameters auto — Sets the expected value to the standard value in the payload type field.
value — Expect a non-standard payload type value in the rx payload type field.
mismatch-reaction
Syntax mismatch-reaction {none | squelch-rx}
Context config>port>otu>psi-payload
Description This command allows the user to configure the consequent action to a psi-payload type mismatch.
Default None

async-mapping
Syntax [no] async-mapping
Context config>port>otu
Description This command allows the user to configure the port to support asynchronous mapping of the payload
