In one embodiment, an apparatus can include a policy vector module configured to retrieve
a compressed policy vector based on a portion of a data packet received at a multi-stage
switch. The apparatus can also include a decompression module configured to receive the
compressed policy vector and configured to define a decompressed policy vector based on
the compressed policy vector. The decompressed policy vector can define a combination of
bit values associated with a policy.
