Syntax
[ default | no ] app-level-retransmission { retain-e2e | set-retransmission-bit }
default
Configures this command with the default setting.
The default behavior is not to set the retransmission bit for a retried Diameter message.

retain-e2e
Sends the same End-to-End Identifier for a retried Diameter message.
set-retransmission-bit
Sets the retransmission bit for retried Diameter messages.
Usage
Use this command to enable application-level transmission with “T” bit set.
'T' bit setting is done only for DIABASE protocol-based rerouting and not for application-based
retransmissions. In order to identify such retransmissions, the server expects the T bit to be set at all levels
(both DIABASE and application) of retransmission, which can be achieved with this CLI command.
In addition to using this CLI command for setting the T-bit in a retried message, it is also possible to retain
the same End-to-End ID. With this feature turned on, the server can detect any duplicate/re-transmitted
messages sent by Diameter clients or agents. Note that this feature is applicable to Gy and Rf messages as
well.
Similar CLI command for setting T-bit is also present under Credit Control Group configuration mode, which
when configured will take effect for Gy messages else endpoint configuration will be used.
