# tc-matchall(8)

traffic control filter that matches every packet

## NAME

matchall - traffic control filter that matches every packet

## SYNOPSIS

**tc** **filter** ... **matchall** \[  **skip\_sw** \| **skip\_hw**  \] \[  **action** *ACTION\_SPEC* \] \[  **classid** *CLASSID* \]

## DESCRIPTION

The **matchall** filter allows one to classify every packet that flows on the port and run a action on it.

## OPTIONS

- **action** *ACTION\_SPEC*

  Apply an action from the generic actions framework on matching packets.

- **classid** *CLASSID*

  Push matching packets into the class identified by *CLASSID*.

- **skip\_sw**

  Do not process filter by software. If hardware has no offload support for this filter, or TC offload is not enabled for the interface, operation will fail.

- **skip\_hw**

  Do not process filter by hardware.

## EXAMPLES

To create ingress mirroring from port eth1 to port eth2:

```
tc qdisc  add dev eth1 handle ffff: clsact
tc filter add dev eth1 ingress                \
        matchall skip_sw                      \
        action mirred egress mirror           \
        dev eth2
```

The first command creates a clsact qdisc with handle **ffff:** on device **eth1** where the second command attaches a matchall filters on it that mirrors the packets to device eth2 for ingress.

To create egress mirroring from port eth1 to port eth2:

```
tc qdisc add dev eth1 handle ffff: clsact
tc filter add dev eth1 egress                  \
        matchall skip_sw                       \
        action mirred egress mirror            \
        dev eth2
```

The first command creates a clsact qdisc with handle **ffff:** on device **eth1** where the second command attaches a matchall filters on it that mirrors the packets to device eth2 for egress.

To sample one of every 100 packets flowing into interface eth0 to psample group 12:

```
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: matchall \
     action sample rate 100 group 12
```
