HostEtherFilter Element Documentation

NAME

HostEtherFilter — Click element; drops Ethernet packets sent to other machines

SYNOPSIS

HostEtherFilter(ETHER [, DROP_OWN, DROP_OTHER, KEYWORDS])

Batching: Batching natively supported
Ports: 1 input, 1-2 outputs
Processing: agnostic, but output 1 is push

DESCRIPTION

Expects Ethernet packets as input. Acts basically like Ethernet input hardware for a device with address ETHER.

In particular, HostEtherFilter sets each packet's packet type annotation to HOST, BROADCAST, MULTICAST, or OTHERHOST based on its Ethernet destination address. Emits most packets on the first output. If DROP_OWN is true, drops packets whose source address is ETHER; defaults to false. If DROP_OTHER is true, drops packets sent to hosts other than ETHER (that is, packets with unicast destination addresses not equal to ETHER); defaults to true. If the element has two outputs, filtered packets are emitted on the second output rather than dropped.

Keyword arguments are:

  • DROP_OWN — Same as the DROP_OWN parameter.
  • DROP_OTHER — Same as the DROP_OTHER parameter.
  • OFFSET — The ethernet header starts OFFSET bytes into the packet. Default OFFSET is 0.
