MirredAction

The MirredAction class supports packet mirroring and packet redirection.

class MirredAction(action_index: Optional[int] = None, *, mirred_action: str, direction: str, to_dev: str)

This class supports the tc(8) mirred action as documented in tc-mirred(8).

Parameters:

• action_index – an integer that effectively names the action

• mirred_action – either mirror or redirect

• direction – either ingress or egress

• to_dev – destination interface

MIRROR = 'mirror'

mirred mirroring action

REDIRECT = 'redirect'

mirred redirect action

EGRESS = 'egress'

Direction for packets to be sent out

INGRESS = 'ingress'

Direction for packets to be received

Returns mirred

get_destination_interface() → str

Returns the name of the destination interface

get_mirred_action() → str

get_direction() → Optional[str]

Returns the direction of the packet when it arrives at the destination interface, either MirredAction.INGRESS or MirredAction.EGRESS

Parse lines common to all actions. Stop when an empty line is encountered (the end of the action)

Sets the action index

set_durations(*, install_duration: int, use_duration: int) → None
