This reference table lists the BigDB variables available for you to configure within the TMOS Shell (
) to customize the way that the BIG-IP system manages web traffic over QUIC.
BigDB variable
When enabled, a set of congestion control parameters are encoded in the resumption token provided to the client and used to initialize the congestion controller on subsequent connections. This variable is enabled by default.
This variable controls the validation of the virtual server that is part of the web traffic configuration. Although it's not supported or recommended, you can disable this variable to use QUIC without HTTP3 or to use QUIC on the server side.
This variable specifies the point at which the BIG-IP system sends RETRY packets to demand address proof. When enabled, this variable verifies that the client is not malicious,similar to the protection that SYN cookies provide for TCP.
This variable logs packets and other events to a format that can be processed by open source tools. This is also a means to obtain a packet trace at the QUIC level. Enable the variable to start capturing, and disable it to stop capturing and finish writing out the capture files. Any trace files are output to
. Note that packets are decrypted prior to logging, although the payload is not logged.
This variable specifies the logging level for the QUIC traffic filter. For more information, see the section titled
