NAME

       nl-qdisc-{add|list|delete} - Manage queueing disciplines

SYNOPSIS

       nl-qdisc-add --dev dev --parent id [OPTIONS] qdisc-type [QDISC]

       nl-qdisc-delete [ --interactive ] [OPTIONS]

       nl-qdisc-list [OPTIONS]

DESCRIPTION

       The nl-qdisc tools allow to manage and configure queueing disciplines (qdiscs) in the kernel.

OPTIONS

       -h or --help
	      Print help text to console and exit.

       -v or --version
	      Print versioning information to console and exit.

       -q or --quiet
	      Do  not  print  informal	notifications  about  actions  taken  to  the  console.   By  default  a  short  description of each qdisc
	      added/update/deleted will be printed to the console. This option disables this behaviour.

       -d or --dev=DEV
	      Network device the qdisc is attached to.

       -p or --parent=ID
	      Identifier of the parent qdisc/class this qdisc is attached to. The identifier can be specified as classid, name or one of the  spe-
	      cial values "root" or "ingress".

       -i or --id=ID
	      Identifier of qdisc. It can be specified as classid or name.

   nl-qdisc-add Options
       --update
	      Update  qdisc  if it already exists, otherwise attempting to add a qdisc which already exists will result in an error. This does not
	      include changing the type of the qdisc, use --replace if you wish to do so.

       --replace
	      Replace or update qdisc if it already exists. Same behaviour as --update but will completely replace the qdisc if it exists already.

       --update-only
	      Update an existing qdisc but do not create it if it does not exist.

       --replace-only
	      Update or replace an existing qdisc but do not create it if it does exist.

   nl-qdisc-delete Options
       --interactive
	      The interactive mode requires confirmation by the user for each qdisc deleted. It will print a prompt for each  qdisc  matching  the
	      provided filter and requires the user to answer 'y'es or 'n'o.

       --yes  Make the default answer for interactive prompts be 'y'es. This option is also required to delete all qdiscs on all network devices.

       -k or --kind=TYPE
	      Only delete qdiscs of this type.

   nl-qdisc-list Options
       --details
	      Show detailed information for each qdisc listed.

       --stats
	      Show statistics information for each qdisc listed. This option will also turn on detailed information automatically.

       -r or --recursive
	      List all TC objects recurisvely attached to all qdiscs matching the filter.

       -k or --kind=TYPE
	      Only list qdiscs of this type.

USAGE

       Add a HTB root qdisc with id "5:":

	      nl-qdisc-add --dev eth0 --parent root --id 5: htb

       List all qdiscs on eth0 and print statistical data:

	      nl-qdisc-list --stats --dev eth0

       Delete the qdisc "5:":
	      nl-qdisc-delete --id 5:
