StrataXGS™ INTEGRATED MULTI-LAYER SWITCH
FEATURES
SUMMARY OF BENEFITS
• 24 x 10/100 Mbits, 4 x 10/100/1000 Mbps Ethernet ports
• 9.5 Mpps (line rate) aggregate L2 switching capacity
• Integrated L2 table (16K) with auto learning/aging
• Double 802.1Q (Q in Q) VLAN stacking
• MPLS tunnel/VC packet labeling for L2 VPN
• Scalable Fast/Gigabit Ethernet in a system
• Eight Classes of Service (COS) with WRED and WRR, DSCP/
802.1p priority
• 256 spanning trees (802.1s and 802.1w)
• 32 link aggregation trunk groups and mirroring
• Up to 256 L2 multicast 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
• High-density 10/100/1000 Mbps L2 Ethernet switches
• 9.5-Mpps, full-duplex, line-rate performance across all
interfaces
• New service offerings for ISPs
• Metro Ethernet-L2 VLAN (Q-in-Q) and MPLS VPN
• Voice Over IP (VOIP)-guaranteed low latency prioritization
• Advanced traffic management-metering, shaping, and
scheduling (SP, RR, WRR, WFQ), down to 64-Kbps flows
• ContentAware classification, tagging, and remapping provides
maximum security and flexibility
• Broadcom switch API compatibility enables software reuse
and faster time-to-market
