产品特性

• Non-blocking switch fabric assures fast packet delivery by utilizing a 1K entry forwarding table and a store-and-forward architecture
• Fully compliant with IEEE 802.3u standards
• Full-duplex IEEE 802.3x flow control (Pause) with force mode option
• Half-duplex back pressure flow control
• IEEE 802.1Q VLAN support for up to 16 groups (full range of VLAN IDs)
• VLAN ID tag/untag options, on a per port basis
• IEEE 802.1p/Q tag insertion or removal on a per port basis (egress)
• Programmable rate limiting at the ingress and egress ports
• Broadcast storm protection
• IEEE 802.1d spanning tree protocol support
• MAC filtering function to filter or forward unknown unicast packets
• Direct forwarding mode enabling the processor to identify the ingress port and to specify the egress port
• Internet Group Management Protocol (IGMP) v1/v2 snooping support for multicast packet filtering
• IPV6 Multicast Listener Discovery (MLD) snooping support
• Integrated LED driver and post amplifier for 10BASE-FL and 100BASE-SX optical modules
• 100BASE-FX/SX and 10BASE-FL fiber support on port 1
• Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port
• MIB counters for fully compliant statistics gathering - 34 MIB counters per port
• Loopback modes for remote failure diagnostics
• Control registers configurable on-the-fly (port-priority, 802.1p/d/Q)
• Per port, 802.1p and DiffServ-based
• Remapping of 802.1p priority field on a per port basis
• Full-chip hardware power-down (register configuration not saved) allows low power dissipation
• Per port-based, software power-save on PHY (idle link detection, register configuration preserved)
• Single power supply: 3.3V
