mode
• Serial interface in unmanaged mode
• Supports one Frame Buffer Memory domain with
SRAM at 100 MHz
• Supports SRAM domain memory size 1 MB or
2 MB
• Applies centralized shared memory architecture
• Up to 64 K MAC addresses
• Maximum throughput is 2.4 Gbps non-blocking
• High performance packet forwarding (7.1431 M
packets per second) at full wire speed
• Provides port based and ID tagged VLAN
support (IEEE 802.1Q), up to 255 VLANs
• Supports IP Multicast with IGMP snooping
• Supports spanning tree with CPU, on per port or
per VLAN basis

-40°C to +85°C
• Packet Filtering and Port Security
• Static address filtering for source and/or destination
MAC
• Static MAC address not subject to aging
• Secure mode freezes MAC address learning
Each port may independently use this mode
• Full Duplex Ethernet IEEE 802.3x Flow Control
• Backpressure flow control for Half Duplex ports
• Supports Ethernet multicasting and broadcasting
and flooding control
• Supports per-system option to enable flow
control for best effort frames even on QoS-
enabled ports
• Traffic Classification
• 4 transmission priorities for Fast Ethernet ports with
2 dropping levels
