Symptoms

On the command line interface, if you specify a data-group record string with the hash ('#') character, then after saving, tmsh encounters a config load error.

Impact

tmsh fails on load.

Conditions

Using the command line interface.

Workaround

To allow the configuration to load add double quotes around # in bigip.conf for data-group string records that include the '#' symbol. For an example ltm data-group internal vf-test { records { # { ----------------> "#" data test2 } } type string } After the configuration has successfully loaded modify the affected data-group replacing the (#) with an alternate string or character combination that does not include the use of "#".

Fix Information

Specify a data-group record string with the hash ('#') character no longer results in a config load error.
