Description
Correction received from the DHCP server to synchronize the router time
clock with the CMTS.
Name of the file stored on the cable company's TFTP server that contains
operational parameters for the router.
Size in bytes of the BCM3300 message buffers.
Indicates the memory location of the beginning of buffer information for the
receive data ring.
Indicates current head buffer descriptor.
Indicates current head packet descriptor.
receive MAC message ring.
Indicates current head buffer descriptor.
Indicates current head packet descriptor.
Indicates the memory location of the beginning of buffer information for the
transmit buffer descriptor ring.
If tx_count is 0, or if tx_head and tx_tail are equal and there is no change for
a period of time, it means there are packets stuck on the ring. This condition
may be caused by the CMTS not giving grants.
Indicates current head transmit packet descriptor.
The next packet descriptor to get used, along with its index.When head_txp
and tail_txp are the same, the transmit queue is empty.
Indicates current tail transmit packet descriptor.
The next packet descriptor to get sent, along with its index. When head_txp
and tail_txp are the same, the transmit queue is empty.
Indicates the memory location of the beginning of buffer information for the
transmit packet descriptor ring.
Indicates current head packet descriptor.
Indicates current tail packet descriptor.
Extended MCNS header.
Number of times the downstream input first-in first-out (FIFO) buffer
became full on the router.
Number of times a bandwidth request generated by the router was not
responded to by the CMTS.
Number of times the router's DMA controller had a downstream MAC
message and there were no free MAC message buffer descriptors to accept
the message.
Number of times the router's DMA controller had downstream data and there
were no free data PDU buffer descriptors to accept the data.
Number of times a MAP message passed all filtering requirements and was
received by the router.
