two output interfaces.
Packet mapping is the process of determining where the data for each field in each
output interface is coming from (as an {input interface, position} pair).
To achieve packet mapping, compare the field name strings. For example, the source
of data for the Red field in a given output interface is the field on an input interface
with the name Red. It is not valid for any field name to exist on multiple-input
interfaces; no two input interfaces may have a Red field. It is valid, however, for
multiple-output interfaces to have the same field; you may copy the Red data to two
or more output interfaces.
A single input or output interface can have multiple instances of the same field. For
example, Red,Green,Red,Blue represents a packet with two red symbols per
packet. The PFC matches the nth instance of a field on an input interface to the nth
instance of the same field on an output interface. If an output interface has
Blue,Green,Red,Red, the data for the first Red field is taken from the first Red
field in the input packet.
Each output interface may or may not use a given input field, but unless you set the
Multi-Packet Mapping option (and if the input field is used) there must be the same
number of instances of the field in each output as there is in the input. For example,
Green and Red,Red,Green are both valid, but Red,Green is not.
Multi-Packet Mapping
Set the Multi-Packet Mapping option, so that the PFC is not limited to mapping a
single input packet on each port to a single output packet on each port. It can map
multiple input packets to multiple output packets.
For example, (Red,Green,Blue)2 maps to (Red,Green,Blue)3 by using three
input packets for every two output packets.
