MCPD config validation error might occur, resulting in an error such as: 01070911:3: The requested integer (0) is invalid for egress_high in profile_mblb This is not an indication of a configuration issue with an MBLB profile. This issue can occur when loading the configuration, or performing a ConfigSync, or during the initial configuration load of mcpd on a secondary blade in a VIPRION chassis.


Config sync fails, or MCPD restarts, and the system logs the message 'requested integer (0) is invalid'.


This occurs under unknown and rare conditions. The BIG-IP configuration does not need to reference MBLB profiles for this issue to occur.


This issue can be mitigated by forcing the mcpd process to reload the configuration as detailed in https://support.f5.com/kb/en-us/solutions/public/13000/000/sol13030.html.

Fix Information

MCPD will no longer trigger a validation error such as "01070911:3: The requested integer (0) is invalid for egress_high in profile_mblb"
