Opened: Nov 04, 2014

Severity: 3-Major


While upgrading, the configuration load fails and you see an error similar to the following: localhost emerg load_config_files: "/usr/bin/tmsh -n -g load sys config partitions all" - failed. -- Syntax Error:(/config/bigip.conf at line: 40) "{" unknown property


Configuration will fail to load on upgrade.


Upgrade to 11.6.x versions may cause iRule compilation failures if the iRule contains whitespace instead of an opening brace after the event. For example: when CLIENT_ACCEPTED {


You can edit bigip.conf and manually correct the line in the iRule by putting the opening brace on tbe same line as the event, then reload the configuration with tmsh load sys config. Example: when CLIENT_ACCEPTED {

Fix Information

Fix tcl parsing if there is a whitespace before the new line.
