Most of the fields in this display are described in Table 15, show dhcp server Field Descriptions. Table 11 describes the MIB statistics shown in the display.

Table 11 show controllers cable-modem MIB Statistics Field Descriptions

Field

Description

DS fifo full

Number of times the downstream receive buffer on the Cisco uBR900 series has

 

become full.

 

 

Rerequests

Number of registration requests sent by the Cisco uBR900 series 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 uBR900 series.

 

 

Qualified syncs

Number of times the Cisco uBR900 series 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 uBR900 series.
