Saku, I noticed that while counters in "show interfaces" output are updated with about 1s interval, then counters asked using SNMP are updated with 5s interval. Platform is MX series router. I *think* I am polling IFD. SNMP IfIndex 723 is from "show interfaces ge-0/0/3" output. I can confirm this with:
$ snmpget -Oq -v 2c -c public 10.10.10.254 ifDescr.723 IF-MIB::ifDescr.723 ge-0/0/3 $ Still, ifInOctets and ifInUcastPkts differ in orders of magnitude from "Input bytes" and "Input packets" counter values in "show interfaces ge-0/0/3 extensive" output. Any ideas? regards, Martin On Mon, May 5, 2014 at 4:41 PM, Saku Ytti <[email protected]> wrote: > On (2014-05-05 18:41 +0300), Martin T wrote: > >> poll the ifInOctets and ifInUcastPkts counters for ge-0/0/3(SNMP >> IfIndex 723) over SNMP: >> >> $ for i in 0 1; do snmpget -Oq -v 2c -c public 10.10.10.254 >> 1.3.6.1.2.1.2.2.1.1"$i".723; done >> IF-MIB::ifInOctets.723 498087262 >> IF-MIB::ifInUcastPkts.723 452255345 >> $ >> >> ..it appears that VLAN sub-interfaces counters are not included.
