Severity: 3-Major


QUIC profile has a field for maximum uni-streams. This represents the number of concurrent uni-streams that the peer can create. If HTTP/3 is also configured on the virtual, then the value for uni-streams should ne >=3. The peer should be able to create at least 3 uni-streams, for control, encoder and decoder.


If fewer than 3 max uni-streams are configured, HTTP/3 transactions will not be successful.


QUIC, HTTP/3, SSL and httprouter profiles are configured on the virtual. QUIC client tries to establish a connection with Big-IP. HTTP/3 is negotiated in ALPN.


Configure correct value of max uni-streams in QUIC profile.

Fix Information

Validation added to prevent a value of less than 3 to be configured when HTTP/3 is also on the virtual.
