On certain Cisco platforms, the ifHCInOctets counters are not populated for certain low-speed interfaces. This poses a dilemma for snmp v3 users. The current scheme for snmp v2 relies on cfgmaker to determine if the ifHCInOctets counters exist, and if not changes the snmp version to "1" instead of 2. But snmp v3 provides not only different counters, but also different authentication methods, so a simple fallback to a different version of snmp is not sufficient.
Possible approaches to fix this: 1. Check every query of ifHCInOctets for "NoSuchInstance" and fall back at run-time within MRTG_lib.pm 2. Create a separate flag in the interface config to query low-speed counters 3. change the line generated by cfgmaker to read something like: Target[slowrouter_Se0_1_0]: ifInOctets#Se0/1\:0&ifOutOctets#Se0/1:0:[EMAIL PROTECTED]::2:1:1:3 Which fix should I work towards? -- Daniel J McDonald, CCIE #2495, CNX, CISSP #78281 Austin Energy gpg Key: http://austinnetworkdesign.com/pgp.key Key fingerprint = B527 F53D 0C8C D38B DCC7 901D 2F19 A13A 22E8 A76A -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
