1.7.2 Retrieve Diagnostics File Button
When you click the Retrieve Diagnostics File button in the Maintenance window, CTC retrieves system
data that can be off-loaded by a Maintenance or higher-level user to a local directory and sent to
Technical Support for troubleshooting purposes. The diagnostics file is in machine language and is not
human-readable, but can be used by Cisco Technical Support for problem analysis. Complete the
following task to off-load the diagnostics file.
In addition to the machine-readable diagnostics file, the ONS 15454 also stores an audit trail of all
Note
system events such as user logins, remote logins, configuration, and changes. This audit trail is
considered a record-keeping feature rather than a troubleshooting feature. Information about the feature
is located in the "Maintain the Node" chapter of the Cisco ONS 15454 Procedure Guide.
Off-Load the Diagnostics File
In the node view, click the Maintenance > Diagnostic tabs
Step 1
Click Retrieve Tech Support Log.

Step 3 In the Saving Diagnostic File dialog box, navigate to the directory (local or network) where you want to
save the file.

Step 4
You do not have to give the archive file a particular extension. It is a compressed file (gzip) that can be
unzipped and read by Cisco Technical Support.
Click Save.
Step 5
The Get Diagnostics status window shows a progress bar indicating the percentage of the file being
saved, then shows "Get Diagnostics Complete."
Click OK.
Step 6
1.7.3 Bidirectional Diagnostic Circuit
CTC provides a diagnostic bidirectional loopback circuit feature that uses pseudo-random bit sequence
(PRBS) error detection to monitor standby path protection, BLSR, 1+1, or unprotected circuit path
readiness.
