Download Getif from http://www.wtcs.org/snmp4tpc/getif.htm Install & run Getif Get the mib file(s) for your Extreme switch Put it in the c:\progra~1\getif\mibs directory. Delete c:\progra~1\getif\mibs\.index Exit Getif Reload Getif Click on the MBrowser tab Navigate to iso -> org -> dod -> internet -> private -> enterprises Extreme should be listed under here. If it isn't, take a look at the c:\progra~1\getif\getif.log file to see if there was an issue when Getif tried to load the mib file. Find the cpu variable (not all vendors support cpu OIDs, so it may not exist, but most higher-end switches have some equivalent) After you find a leaf node that you want to collect data on, take the OID from Getif (it will be listed at the top) and do some snmpwalks against it to see if it returns valid data like: snmpwalk myswitch public .1.3.6.1.4.1.1991.1.1.2.11.1.1.4 (the above example is the CPU oid for a Foundry switch) After you have a good OID, you can manually build a MRTG config with it, or work it into a template such as http://mrtg.gvolk.com/template/host-ios.template which is more maintainable and a lot easier to use via cfgmaker. The host-ios.template file is for a cisco, but just replace the cisco CPU OID with your Extreme CPU oid and delete the mem free template. -- 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
