The BCM5650 network switch is the most advanced multi-layer, single chip solution for high density 24 x 10/100 Mbps ports and 4 x 10/100/1000 Mbps Ethernet uplinks.
With an aggregate line rate of 9.5 Mpps, the BCM5650 offers hardware switching on both L2 and L3 traffic. Filtering, policing, priority tagging can be performed in real time with no impact on forwarding performance.

FEATURES
• 24 x 10/100 Mbits, 4 x 10/100/1000 Mbps Ethernet ports
• 9.5 Mpps (line rate) aggregate L2/L3 switching capacity
• Integrated L2 table with auto learning/aging
• Integrated L3 table with longest prefix match
• Double 802.1Q (Q in Q) VLAN stacking
• MPLS Tunnel/VC packet labeling for L2 VPN
• Scalable to hundreds Fast/Gigabit Ethernet in a system
• 8 Classes of Service (COS) with WRED and WRR, DSCP/802.1p priority
• Spanning trees (802.1s and 802.1w)
• 32 link aggregation trunk groups; ECMP/WCMP; mirroring
• IPMC groups and hardware packet replication
• Flow control (802.3x) and HOL blocking prevention
• 64 data bit DDR SDRAM with up to 32 MB of buffer memory
• ContentAware™ network processing per port
• Line-rate, multi-field packet classification
• Support for 802.1p, TOS/DiffServ, rate limiting, policing, and priority/VLAN (single or double) tagging and remapping
