General Description
The KSZ8895MQX/RQX/FQX/ML is a highly-integrated, Layer 2 managed, five-port switch with numerous features designed to reduce system cost. Intended for cost-sensitive 10/100Mbps five-port switch systems with low power consumption, on-chip termination, and internal core power controllers, it supports high-performance memory bandwidth and shared memory-based switch fabric with non-blocking configuration.
Features
Advanced Switch Features
• IEEE 802.1q VLAN support for up to 128 active VLAN
groups (full-range 4096 of VLAN IDs).
• Static MAC table supports up to 32 entries.
• VLAN ID tag/untag options, per port basis
• IEEE 802.1p/q tag insertion or removal on a per port
basis based on ingress port (egress).
• Programmable rate limiting at the ingress and egress
on a per port basis.
• Jitter-free per packet based rate limiting support.
• Broadcast storm protection with percentage control
(global and per port basis).
• IEEE 802.1d rapid spanning tree protocol RSTP
support.
• Tail tag mode (1 byte added before FCS) support at
Port 5 to inform the processor which ingress port
receives the packet.
• 1.4Gbps high-performance memory bandwidth and
shared memory-based switch fabric with fully nonblocking configuration.
