8 PORT ETHERNET SWITCH

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND PMC-SIERRA, INC. CUSTOMERS ONLY

LPDPtr:

24-bit address of the local port descriptor assigned to the physical ELAN

8x10 port associated with this MAC address.

HBFlags:

8-bit per-MAC control flags, formatted as described below.

TXFrames:

32-bit count of total number of frames transmitted to this MAC address.

TXOctets:

32-bit count of total number of bytes transmitted to this MAC address.

RXErrorFrames:

32-bit count of frames received from this MAC address with errors.

RXMcstFrames:

32-bit count of valid multicast (i.e., IEEE 802.3 group/functional address)

frames received on this port.

RXFloodFrames:

32-bit count of frames received on this port which need to be flooded.

RXBcstFrames:

32-bit count of valid broadcast frames received on this port

RXUcstFrames:

32-bit count of valid unicast frames received on this port.

RXOctets:

32-bit count of total bytes (errored or otherwise) received on this port.

AgeControl:

32-bit timestamp (obtained from the CLOCK register pair within the Switch

Processor) when a frame was last received from this MAC address.

CreateTime:

32-bit timestamp (obtained from the CLOCK register pair within the Switch

Processor) when this hash bucket was created.

The NextHB field contains a 24-bit pointer to the next hash bucket (or forwarding tag) in

the linked-list of hash buckets. It is NULL (all-zeros) if this hash bucket forms the end of

the chain. The MACAddr field spans two consecutive words, and contains the complete

48-bit MAC address associated with this hash bucket; it is compared to the address

extracted from the Ethernet packet during the address table lookup process to ensure

that the proper hash bucket has been found.
