This is a great clarification.
Thanks for correcting me, Gil. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Amos Shapira Sent: Monday, May 14, 2007 6:41 AM To: [email protected] Subject: Re: [mrtg] Monitor TenGiga ports On 14/05/07, Mizrahi, Gil <[EMAIL PROTECTED]> wrote: Hi, 64 bit counters were created to collect high capacity traffic (Giga and above). The "regular" counters are 32 bit. MRTG needs a special sign that tells to work with the 64 bit counters. This sign is ':::::', e.g. [EMAIL PROTECTED]:::::2. As I said before it has significance when collecting Giga port and above (TenGiga ...). As I know it doesn't have anything with the SNMP version. It has everything to do with SNMP version. Please read the documentation. In "mrtg-reference", under "Extended Host Name Syntax" there is explanation for the fields which are delimited by these ":". It's just that most of the time people don't care to change the default timeout or number of retries, but that pesky "2" at the end actually tells MRTG to use SNMP v2 (as opposed to the default of v1), and you have to skip all the other fields in front of it. It's simply that v2 introduced support for 64-bit counters. What you call "regular" counters (actually 32 bit counters) are simply the only ones supported by the default SNMP version used by MRTG - v1.
