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
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
