nl-qdisc-list
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:
