ABSTRACT:
An integrated multiport switch (IMS) in which an on-chip management information base (MIB) accumulation processor enables monitoring of a significantly larger number of MIB objects to be stored in external memory while minimizing media access controller (MAC) complexity. A MAC for each port in the IMS outputs a MIB report for each transmission or reception of data according to a specific encoded format to a MIB engine. The MIB engine decodes the MIB report into a plurality of associated MIB objects, which are temporarily accumulated until the external memory is updated. The MIB engine initiates the stored MIB value updating process by retrieving the values from the external memory and adding the accumulated MIB objects to the retrieved values. The updated MIB objects are then transmitted back to the external memory for storage therein and the MIB engine object values are reset.
