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).
sifRxChar0s
 - The number of characters in the forwarded received 
packets.
sifRxChar1s
 - The number of characters in the filtered received 
packets.
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.
