| Description | The Cable Modem Interface Mask (CMIM) signaled in a
Packet Classifier Encoding. In a Downstream Packet
Classifier Encoding, a specified CMIM value restricts the
classifier to match packets with a Destination MAC address
corresponding to the interfaces indicated in the CMIM mask.
The eCM self and any eSAFE interface bits correspond to
the individual eCM and eSAFE host MAC addresses.
In an Upstream Packet Classifier encoding, a specified CMIM
value restricts the classifier to match packets with an
ingress bridge port interface matching the bits in the
CMIM value.
If the CMIM subtype was omitted, this object should be
reported as a zero length octet string. |
