Tree protocol

Supports 802.1p and/or DiffServ with four priority queues

Supports 802.3ad link aggregation control protocol (LACP)

and marker protocol

Supports selected MIB groups in RMON and SMON

Supports up to 32K IP multicast groups with the option to cross

VLAN boundaries

Full-duplex and half-duplex operation with IEEE 802.3x flow

control and backpressure

Built in 32-bit, 33-MHz PCI bus interface

Flexible multiplexer modes

BCM5632

Complete switch on a chip integrates 12 10/100/1000 and one

10G Ethernet Media Access Controllers (MACs) supporting

RMII, GMII, XGMII and TBI interfaces, including multi-

layer forwarding and filtering logic and internal ARL tables

and packet buffering.

Supports 32K internal MAC addresses, which are shared by

all ports. Multicast MAC addresses, including IP multicast,

can also be stored and searched.

Supports Quality of Service (QoS). Each output port has four

priority queues and their assignment can be based on DiffServ

TOS field or the 802.1p priority field.

Filters and forwards traffic at full wire speed on all 13 ports at

all layers of functionality. This equates to 44 Gbps of

bandwidth.

Provides a mechanism to bundle together up to 12 ports at the

same speed to form a port bundle or a trunk group,

establishing up to six trunk ports.

... Aggregation Control Protocol (LACP) frames are handled by the accompanying CPU and the marker protocol is handled in hardware. The BCM5632 can be initialized and configured by an EEPROM or a CPU, which is also responsible for search table updates and management functions. The CPU is a separate port to the device, containing its own Tx FIFO and Rx FIFO ...
