Network Interface Drivers with ALTQ Traffic Shaping Support

This section provides information regarding drivers in FreeBSD which support ALTQ.

Information

The ALTQ framework is used for queuing/traffic shaping. In pfSense® software, this is utilized by the Shaper Wizard and the Queues/Interfaces tabs under Firewall > Traffic Shaper.

See the altq(4) manual page or the altq(9) manual page.

On those pages, select the version of FreeBSD that corresponds to the pfSense software version being run.

In addition to the drivers listed as supporting ALTQ in FreeBSD, pfSense software also includes support for ALTQ on vlan(4) and IPsec enc(4) interfaces.

If a driver does not support ALTQ, traffic shaping can be performed by Limiters instead.
