Hi all, I am monitoring total number of modems in use using mrtg, and using this OID for that 1.3.6.1.4.1.429.4.2.1.10.0 (using HiperArc,6 Hiperdsp-e1r2) Its giving me some more values than actual modems in use( i.e I am manually doing 'list connections' on hiperarc than 48 connections are there and the same time doing snmpwalk using this OID giving me 64 . ) Is this problem of snmp or something wrong with the modems??? And day by day this differance is increases.......After rebooting the chassis , again its working ok,,,,,, and after passing days again day by day it increasing. I am also observing per slot using this OID 1.3.6.1.4.1.429.4.10.35.1.3.0 and the total of all the 6 slots is mathing exactly with the list connections result. Thanks pankaj
