[root@localhost vpp]# tc action help
usage: tc actions <ACTSPECOP>*
Where: ACTSPECOP := ACR | GD | FL
ACR := add | change | replace <ACTSPEC>*
GD := get | delete | <ACTISPEC>*
FL := ls | list | flush | <ACTNAMESPEC>
ACTNAMESPEC := action <ACTNAME>
ACTISPEC := <ACTNAMESPEC> <INDEXSPEC>
ACTSPEC := action <ACTDETAIL> [INDEXSPEC]
INDEXSPEC := index <32 bit indexvalue>
ACTDETAIL := <ACTNAME> <ACTPARAMS>
Example ACTNAME is gact, mirred, bpf, etc
Each action has its own parameters (ACTPARAMS)
[root@localhost vpp]# tc qdisc help
Usage: tc qdisc [ add | del | replace | change | show ] dev STRING
[ handle QHANDLE ] [ root | ingress | clsact | parent CLASSID ]
[ estimator INTERVAL TIME_CONSTANT ]
[ stab [ help | STAB_OPTIONS] ]
[ [ QDISC_KIND ] [ help | OPTIONS ] ]
tc qdisc show [ dev STRING ] [ ingress | clsact ]
Where:
QDISC_KIND := { [p|b]fifo | tbf | prio | cbq | red | etc. }
OPTIONS := ... try tc qdisc add <desired QDISC_KIND> help
STAB_OPTIONS := ... try tc qdisc add stab help
