Traefik supports [systemd socket activation](https://www.freedesktop.org/software/systemd/man/latest/systemd-socket-activate.html).
When a socket activation file descriptor name matches an EntryPoint name, the corresponding file descriptor will be used as the TCP listener for the matching EntryPoint.
When a socket activation file descriptor name matches an EntryPoint name, the corresponding file descriptor will be used as the TCP/UDP listener for the matching EntryPoint.

!!! warning "EntryPoint Address"
When a socket activation file descriptor name matches an EntryPoint name its address configuration is ignored.
!!! warning "TCP Only"
Socket activation is not yet supported with UDP entryPoints.
When a socket activation file descriptor name matches an EntryPoint name its address configuration is ignored. For support UDP routing, address must have /udp suffix (--entrypoints.my-udp-entrypoint.address=/udp)
!!! warning "Docker Support"
Socket activation is not supported by Docker but works with Podman containers.
!!! warning "Multiple listeners in socket file"
Each systemd socket file must contain only one Listen directive, except in the case of HTTP/3, where the file must include both ListenStream and ListenDatagram directives. To set up TCP and UDP listeners on the same port, use multiple socket files with different entrypoints names.
## Observability Options
This section is dedicated to options to control observability for an EntryPoint.
