BCM5632
12 GIGABIT + 1 10-GIGABIT SWITCHING PROCESSOR
BCM5632 Switching Solution
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
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.
