General Description
●The KS8995MA/FQ is a highly-integrated Layer 2 managed switch with optimized bill of materials (BOM) cost for low port count, cost-sensitive 10/100Mbps switch systems with both copper and optic fiber media. It also provides an extensive feature set such as tag/port based VLAN, quality of service (QoS) 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 non blocking configuration
●• 1.4Gbps high-performance memory bandwidth
●• 10BASE-T, 100BASE-TX, and 100BASE-FX modes
●• 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 in 32Kbps increments
●• 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 % control – global and per-port basis
●• Optimization for fiber-to-copper media conversion
●• Full-chip hardware power-down support (register configuration not saved)
●• Per-port based software power-save on PHY (idle link detection, register configuration preserved)
●• QoS/CoS packets prioritization supports:
● − Per port, 802.1p and DiffServ based
●• 802.1p/q tag insertion or removal on a per-port basis (egress)
●• MDC and MDI/O interface support to access the MII PHY control registers (not all control registers)
●• MII local loopback support
●• On-chip 64Kbyte memory for frame buffering (not shared with 1K unicast address table)
●• Wire-speed reception and transmission
●• Integrated look-up engine with dedicated 1K MAC addresses
●• Full duplex IEEE 802.3x and half-duplex back pressure flow control
●• Comprehensive LED support
●• 7-wire SNI support for legacy MAC interface
●• Automatic MDI/MDI-X crossover for plug-and-play
●• Disable automatic MDI/MDI-X option
