Hi, it is obvious that MIB's are important for network management stations as otherwise SNMP queries based on object names would not work. For example:
$ snmpget -M /dir/that/does/not/exist -On -v 2c -c public 10.10.10.1 sysUpTimeInstance 2>/dev/null $ snmpget -M /dir/that/does/not/exist -On -v 2c -c public 10.10.10.1 .1.3.6.1.2.1.1.3.0 2>/dev/null .1.3.6.1.2.1.1.3.0 = Timeticks: (69843635) 8 days, 2:00:36.35 $ Another purpose of MIB's I can see is that they help to make sense of returned values. For example here I don't have Cisco MIBs installed and it is difficult to understand what "33939721.372808280" or "68690115.642234535" means: $ snmpwalk -Of -v 2c -c public 10.10.10.1 .1.3.6.1.4.1.9.9.166.1.17.1.1.9 | head -3 .iso.org.dod.internet.private.enterprises.9.9.166.1.17.1.1.9.33939721.372808280 = Counter32: 0 .iso.org.dod.internet.private.enterprises.9.9.166.1.17.1.1.9.68690115.642234535 = Counter32: 0 .iso.org.dod.internet.private.enterprises.9.9.166.1.17.1.1.9.68690115.724494656 = Counter32: 0 $ On the other hand, here I have required MIB databases installed and I can easily see that those entries represent interface names: $ snmpwalk -Of -v 2c -c public 10.10.10.1 .1.3.6.1.2.1.31.1.1.1.1 | head -3 .iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.2 = STRING: Null0 .iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.3 = STRING: MgmtEth0/RSP0/CPU0/0 .iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.4 = STRING: MgmtEth0/RSP0/CPU0/1 $ Is there any additional purpose of MIB files in SNMP management stations? thanks, Martin ------------------------------------------------------------------------------ Don't Limit Your Business.
