General Description

The KSZ8895MQ/RQ/FMQ 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.
