Hi,

I have an issue with MRTG 200Mbps graph, please help me how to check snmp version on Cisco 3750 switch, how to check whether switch is working on 32 bit counters or 64 bit counters. If the switch is working on 32 bit counters how to change in to 64 bit counters.


Thanks & Regards

the switch either has high capacity (xxHCxxx) counters or it doesn't. Use snmpwalk to see the list of available OIDs (be sure you use 2c version o SNMP since the HC counters are not accessible under SNMP version 1). There is no way to change the switch counter behavior (IMHO) you just need to use another OID/name of the SNMP counter (ifHCInOctets instead of ifInOctets, etc)

Thanks for the information could you please help me with commands and steps to check snmp version and counters 32 or 64

Thanks

this topic doesn't belong in a mikrotik forum

Could you please educate me where I have to change the OID/Name of the SNMP counter (ifHCinOctets instead of ifinOctets) (In MRTG server of Cisco 3750 switch) Please help me with step by step.

Thanks

I am using 35 Mikrotik Router in my current network the graph with mikrotik routers its fine but the mail in-put is Cisco 3750 so let me see any help from this form.

Thanks

in mrtg CFG of course. We are now using MRTG only for some minor tasks (we have our own DB driven app instead) so I don't know presisely how to configure the MRTG for HC counters. But it looks like you have to check 'SNMPv2' and 'Target[]' or maybe even 'noHC[]' option syntax. Read the manual or use google for "mrtg 64 bit counter" etc
