The capture of a Cisco NXS Configuration File via a perl script fails with error messages:

Login Error: Use of uninitialized value in concatenation (.) or string at

c:\Windows\TEMP\script_13 line 110


Login has failed. Output:

The Spectrum logs return:

Jun 18 23:00:00 ERROR TRACE at timer registration for tag 2 failed


Check if the script can be executed from outside the NCM via the command line.

Open a bash shell move to the $SPECROOT/bin/perl directory and execute the script in the following way:

<script_file> <device_ip> <device_username> <device_password> <device_enable_password> <telnet_login_timeout>[<telnet_cmd_timeout>]

If the script returns the same error message, check if the regenerate of the crypto-key at the device can solve the issue.
