switching and routing at L2, L3, and L4
48 Ethernet ports, 10/100/1000 Mbit operation
Non-blocking architecture, line rate for all packet sizes
Purpose-built for IPv6 networks
External TCAM allowing L2, L3, and ACL expansion
Metro ready: comprehensive MPLS tunneling engine (support for
L2/3 VPNs)
Carrier-class 802.1ad support, with expanded support for multi-
tag transformations
Support for large L2 VPNs and L3 VPNs
Enhanced on-chip packet buffer optimized for burst absorption
and multicast at low latency
Multistage classification engine for per-flow or user group
security and QoS
Broadcom’s exclusive microflow-based policing
Weighted random early detection congestion avoidance
Intelligent scheduling (SP, WRR, DFQ)
Flow Control: Link pause, per CoS priority, and Service Aware
