The list of interfaces to which the traffic needs
to be mapped to.
This object is a list of interfaces presented as
an Octet string of interface indices or ifindex-es.
The list should contain at least one interface and at most
all the interfaces in the switch up to 64 interfaces.
The 64 interfaces max-limit is due to the size of this
object.
Specifying this object is mandatory for the creation of a
row in cnpvTrafficMapTable.
