BCM5631

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

10G Ethernet Media Access Controllers (MACs) supporting

RMII, GMII, and TBI interfaces, including multilayer

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 wirespeed on all 12 ports at

all layers of functionality. This equates to 24 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.
