Apr 23 10:43:04.369 2009 re0.router mgd[58819]: UI_CMDLINE_READ_LINE: User 'cm', command 'xml-mode netconf need-trailer '

Solution

xml-mode netconf need-trailer is a shell level command which is executed by the user. This command will turn on the ' ]]>]]> ' trailer. This command was introduced for netconf with the introduction of ' ]]>]]> ' as the end-of-frame token.

See the below link for netconf draft.

IEFT NETCONF Configuration Protocol over Secure Shell

The above link states the following:

As the previous example illustrates, a special character sequence,
]]>]]>, MUST be sent by both the client and the server after each XML
document in the NETCONF exchange. This character sequence cannot
legally appear in an XML document, so it can be unambigiously used to
indentify the end of the current document, allowing resynchronization
of the NETCONF exchange in the event of an XML syntax or parsing
error.

These messages have no impact and can be ignored.
