switch. System designers can also use this ARL interface to implement a vendor-specific
address resolution algorithm.
Register & UART Interface
A System CPU can access various registers inside the ACD82224 through a serial CPU
management interface (UART). The CPU can configure the switch by writing into the appropriate
registers, or retrieve the status of the switch by reading the corresponding registers within the
ACD82224 switch. The CPU can also access the registers of external transceiver (PHY) devices
through the CPU management interface as well.
External-MIB & External-MIB Interface
The ACD82224 provides management support through the use of the ACD80900 (Management
Information Base). The MIB interface can be used to monitor all traffic activities of the switch
system. The supporting chip (the ACD80900) provides a full set of statistics counters to support
both SNMP and RMON network management functions. In addition to the statistics counters, the
ACD80900 also support all groups of RMON management, including Host, HostN, Matrix,
Filtering and Capturing groups. System designers can also use the MIB interface to implement
vendor-specific network management functionality.
