Brief
12 GIGABIT + 1 10-GIGABIT SWITCHING PROCESSOR
BCM5632 FEATURES
• Supports 12 Gigabit ports and one 10-Gigabit uplink
in wirespeed operation
• Gigabit ports support TBI (1000BASE-X) or GMII
(1000BASE-T) interfaces
• Uplink supports XGMII interface for 10-Gigabit
• L2 search table supports 32K MAC addresses
• Jumbo Frame support (9 KB)
• Supports 4K VLAN address and 802.1s Multiple
Spanning 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
• Packaged in 785-pin BGA
SUMMARY OF BENEFITS
• 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.
