Description (partial)


Counters such as "ifInDiscards" in "show counters interface" is not the same ifInDiscards value in IF-MIB (RFC1213/RFC1573) via SNMP. It only represents "input_drops".

If one does an SNMP Walk of ifInDiscards in IF-MIB, it will show a different value which includes:

ifInDiscards = counters.output_nobuffers + counters.input_drops +  RP.input_drops

And the corresponding CLI show commands are:

"show int <interface> | inc no buffer"  (for"output_nobuffers") and
"show counter int <interface> | inc  ifInDiscards"  (for "input_drops") and
"show int <interface> switching | inc RP"  (for RP.input_drops)

The "show int <interface> switching | inc RP" can also be the counter for  Input queue "drops" in "show int <interface> | inc drops".


This affects all versions and many other counters in "show counters interface" may not be the same as the counters with the same names in IF-MIB.
