General Description
The KS8995M is a highly integrated Layer-2 managed switch with optimized BOM (Bill of Materials) cost for low port count, cost-sensitive 10/100Mbps switch systems. It also provides an extensive feature set such as tag/port-based VLAN, QoS (Quality of Service) priority, management, MIB counters, dual MII interfaces and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.

FEATUREs
• Integrated switch with five MACs and five Fast Ethernet transceivers fully compliant to IEEE 802.3u standard
• Shared memory based switch fabric with fully nonblocking configuration
• 1.4Gbps high-performance memory bandwidth
• 10BaseT, 100BaseTX and 100BaseFX modes (FX in Ports 4 and 5)
• Dual MII configuration: MII-Switch (MAC or PHY mode MII) and MII-P5 (PHY mode MII)
• IEEE 802.1q tag-based VLAN (16 VLANs, full-range VID) for DMZ port, WAN/LAN separation or inter-VLAN switch links
• VLAN ID tag/untag options, per-port basis
• Programmable rate limiting 0Mbps to 100Mbps, ingress and egress port, rate options for high and low priority, per-port-basis
• Flow control or drop packet rate limiting (ingress port)
• Integrated MIB counters for fully compliant statistics gathering, 34 MIB counters per port
• Enable/Disable option for huge frame size up to 1916 bytes per frame
• IGMP v1/v2 snooping for multicast packet filtering
• Special tagging mode to send CPU info on ingress packet’s port value
• SPI slave (complete) and MDIO (MII PHY only) serial management interface for control of register configuration
• MAC-id based security lock option
• Control registers configurable on-the-fly (port-priority, 802.1p/d/q, AN...)
• CPU read access to MAC forwarding table entries
• 802.1d Spanning Tree Protocol
• Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port or MII
• Broadcast storm protection with percent control – global and per-port basis
• Optimization for fiber-to-copper media conversion
• Full-chip hardware power-down support (register configuration not saved)
