show quic

Display details on active QUIC frontend connections.

Description

The show quic command displays details on active QUIC frontend connections.

An optional argument can be specified to control the verbosity. Specify either oneline, the default, or full.

By default, connections on closing or draining state are not displayed. To include them in the output, specify the additional argument all.

This command requires a permission level of operator or admin.

This command is available only on the QUIC-enabled HAProxy Enterprise load balancer. For details, see HTTP/3
