string identifier — 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...(up to 64 bytes)] — 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. A 1 byte sequence of 0xFF will
set the default strings.
Values 0 — FF, in hexidecimal byte notation
tx
Syntax tx {auto-generated | string identifier | bytes byte1 [byte2...(up to 64 bytes)]}
no tx
Context config>port>otu>sm-tti>tx
Description This command allows the user to configure the transmit (tx) trail trace identifier (TTI) for section monitor-
ing (SM) in the OTU 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.
The no form of the command reverts to the default TTI.
Default Auto-generated in the format of nodename:iomnum/mdanum/portnum/dwdmchan
The auto-generated value has five sections:
• Nodename — The first section is the name of the node.
• iomnum — The second section contains the IOM slot number.
• mdanum — The third section contains the MDA slot number.
• portnum — The fourth section contains the port number.
• dwdmchan — The fifth section contains the DWDM channel number (see Table 32, DWDM
Channel Numbers, on page 334).
Parameters auto-generated — Specifies to use the system generated (default) TTI.
string identifier — Sets the SM TTI to the string provided by the user. If the string is less than 64 bytes, the
remaining bytes will be set to 0.
bytesbyte1 [byte2...(up to 64 bytes)] — Sets the SM 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. A 1 byte sequence of 0xFF will
set the default strings.
Values 0 — FF, in hexidecimal byte notation
