Bug ID 739400: iControl REST fails to list virtual servers

Last Modified: Jan 10, 2023

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
13.1.0,,,,,,,,, 13.1.1,,,,, 13.1.3,,,,,,, 13.1.4,, 13.1.5,

Opened: Aug 06, 2018

Severity: 3-Major


An attempt to add a forward action to an LTM policy generated an error. A separate attempt to use iControl REST to list virtual servers also failed.


In iControl REST, the character causes an error response, which prevents a response with a listing of virtual servers.


Insert a non-breaking space ( ) character in the description field of a virtual server entry. Try to create a forward action using the TMUI on BIG-IP version, or use iControl REST to list virtual servers.


Verify that the description field for a virtual server does not contain any characters like non-breaking spaces. Avoid copying and pasting content into description fields, especially if the source is HTML format since it may contain a non-breaking space character.
