Most of the fields in this display are described in Table 2, Show Controllers Cable-Modem Field Descriptions. Table 7 describes the MIB statistics shown in the display.

Table 7	Show Controllers Cable-Modem MIB Statistics Field Descriptions
Field		Description
DS fifo full		Number of times the downstream receive buffer on the Cisco uBR924 has become full.
Rerequests		Number of registration requests sent by the Cisco uBR924 to the CMTS.
DS mac msg overruns		Number of times the DMA controller has had a downstream MAC message and there
		were no free MAC message buffer descriptors to accept the message.
DS data overruns		Number of times the DMA controller has had downstream data and there were no free
		data PDU buffer descriptors to accept the data.
Qualified maps		Number of valid MAP messages received by the Cisco uBR924.
Qualified syncs		Number of times the Cisco uBR924 has received synchronization with the downstream
		channel.
CRC fails		Number of cyclic redundancy checksums generated by the far-end device that did not
		match the checksums calculated from the message portions of the packets received.
HDR check fails		Number of cyclic redundancy checksums generated by the far-end device that did not
		match the checksums calculated from the MAC headers of the packets received. The
		MAC header CRC is a 16-bit Header Check Sequence (HCS) field that ensures the
		integrity of the MAC header even in a collision environment.
Data pdus		Total number of data PDUs (protocol data units) of all types received by the cable
		interface.
Mac msgs		Number of MAC messages received by the cable interface.
Valid hdrs		Number of valid MAC headers received by the cable interface.

Below the MIB statistics in the show controllers cable-modem 0 mac hardware display, the BCM3300 registers section shows the DMA locations of the indicated processing routines of the Broadcom 3220 MAC chip within the Cisco uBR924.
