Chapter 4: Statistics

-Remove Received - The Token Ring port has removed itself from the ring.

NOTE

All of the counter values are reset to zeros if the ATX is rebooted or if the module housing that port is halted and restarted.

4.2 MODULE STATISTICS

Interface-related statistics are maintained for NMS examination in several portions of the management information base (MIB). These include the “if” portion of MIB II, the bridge MIB[5], the 802.5 MIB, and proprietary MIB entries. The proprietary MIB port statistics are summarized below:

•sifRxPackets - The number of received packets by category. Each of the possible 25 categories is the cross-product of the five destination addresses and the five forwarding outcomes (see Table 4-1).

Table 4-1 Destination Addresses and Forwarding Outcomes
