Description
Indicates the location of the upstream interface.
Indicates the administrative state of the upstream interface.
Number of broadcast packets received through this upstream
interface.
Number of multicast packets received through this upstream
interface.
Number of unicast packets received through this interface.
Number of packets discarded by this interface, typically because of
buffer overruns.
Total of all packets with errors that prevented the transmission of
the packets through this upstream interface. This figure could
include the following errored packets:

On Broadband Processing Engines (BPE) cable interface line
cards, such as the Cisco uBR-MC16U/X, Cisco uBR-MC28U/X,
and Cisco uBR-MC5X20S/U cards, this counter also counts
conditions such as HCS/CRC errors and collisions that occur
during initial ranging requests and bandwidth requests. Compare
this counter with the uncorrectable error counter from the
cable hop
exists, or whether the counter is high only because a large number
of CMs are trying to register.

Collisions of request and request/data packets
Damaged frames received during request and request data
requests or slots (typically because they had bad forward error
correction (FEC) header checksums (HCS)
Damaged frames received from ranging requests
Data packets with unique word, collision or no energy
Number of upstream bursts whose preamble or unique word
could not be correctly received
Packets with at least one frame with an uncorrectable error
command to determine whether a problem with noise
