Features
Eight Gigabit Ports with GMII and PCS interface
-
Gigabit Port can also support 100/10 Mbps MII
interface
High Performance Layer 2 Packet Forwarding
(23.808M packets per second) and Filtering at
Full-Wire Speed
Maximum throughput is 8 Gbps non-blocking
Centralized shared-memory architecture
Consists of two Memory Domains at 133 MHz
-
Frame Buffer Domain: Two banks of ZBT-SRAM
with 2M/4MB total
-
Switch Database Domain with 256K/512K
SRAM
Up to 64K MAC addresses to provide large node
aggregation in wiring closet switches
Traffic Classification
Classify traffic into 8 transmission priorities per
port
Supports Delay bounded, Strict Priority and WFQ
Provides 2 level dropping precedence with WRED
mechanism
-
User controlled thresholds for WRED
Classification based on layer 2, 3 markings
-
VLAN Priority field in VLAN tagged frame
-
DS/TOS field in IP packet
The precedence of above two classifications can
be programmable
