NAME

       nl-pktloc-lookup - Lookup packet location definitions

SYNOPSIS

       nl-pktloc-lookup name
       nl-pktloc-lookup --list

DESCRIPTION

       nl-pktloc-lookup searches the packet location database for a matching entry. It is used to resolve packet location aliases to their defini-
       tion, i.e. alignment, layer, offset, and mask.

OPTIONS

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

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

       -l or --list
	      List all packet location definitions.

       --u32=VALUE
	      Prints the packet location definition in a special format that is understood by iproute2's u32 selector parser. It will output a u32
	      selector which will compare the provided value with the value specified by the packet location.

	      Please  note that due to the limitation of u32, it is not possible to use packet locations based on the link layer. nl-pktloc-lookup
	      will print an error message in this case.

	      Example:
		selector=$(nl-pktloc-lookup --u32 22 tcp.sport)
		tc filter add [...] u32 match $(selector) flowid 1:2

nl-qdisc(8)						      System Manager's Manual						       nl-qdisc(8)

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:
