12 GIGABIT + 1 10-GIGABIT SWITCHING PROCESSOR
FEATURES
SUMMARY OF BENEFITS
• 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 Kbyte)
• Supports full 4K VLAN addresses 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 an 841-pin or a 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 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 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.
