Fixed In:

Opened: Jun 06, 2019 Severity: 3-Major
Default values differ between tmsh and GUI documentation, and actual behavior. The special value 0 is documented to either disable the respective limit or apply a default value. Actual behavior for 0 is to silently apply internal default values of 32768 bytes and 256 messages, regardless of the protocol. These defaults might not match the profile default values for a given MRF protocol such as Diameter, SIP, or MQTT. For some protocols such as Diameter, there is no validation of whether the maximum pending messages value falls within the acceptable range of 1-65535, and values outside that range are silently truncated to 16-bits and then 0 is treated according to the actual behavior described above. Some documented and actual default values have changed across releases.
Depending on the protocol, the limits might not take effect as configured. Incorrect documentation and/or lack of validation could lead to configuring an invalid value.
An MRF router profile is configured with the 'Maximum Pending Bytes' or 'Maximum Pending Messages' parameter set to a non-default value or 0. Affected MRF router profiles are: 'diameter', 'sip', 'mqtt' and 'generic'.
None.
Default values of MRF router profile parameters 'Maximum Pending Bytes' and 'Maximum Pending Messages' are validated and applied as documented. The default value in an MRF router profile is as documented for the protocol. Documentation is consistent for tmsh '?' help, the 'help' command, and the GUI. A value of 0 may not be configured; if an old configuration with a value of 0 is loaded, the value is automatically converted to the default value.
