RE: Are MIB files also used for converting SNMP GetResponse *values*?

Look for display hints in, for example, the TC MIB here: https://tools.ietf.org/html/rfc2579

Subject: Are MIB files also used for converting SNMP GetResponse *values*?

Hi,

I am aware that MIB files in NMS are used to translate OID integers in SNMP GetResponse messages into meaningful names. For example here I can see that string "Vl290" is an VLAN-interface name:

$ snmpget -Of -v 2c -c public 10.10.10.1 .1.3.6.1.2.1.31.1.1.1.1.290
.iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.290
= STRING: Vl290
$


Without Cisco MIBs I would see:

$ snmpget -m /dev/null -Of -v 2c -c public 10.10.10.1
.1.3.6.1.2.1.31.1.1.1.1.290
.iso.3.6.1.2.1.31.1.1.1.1.290 = STRING: "Vl290"
$


However, are MIB files also used for converting SNMP GetResponse values? I mean for example "snmpwalk -Ov -v 2c -c public 10.10.10.1 sysUpTimeInstance" returns "Timeticks: (88920401) 10 days, 7:00:04.01", but this conversion is done in snmpget/snmpwalk utility itself. For example is it possible to define in MIB files that for example 1099 integer32 value in SNMP GetResponse message should be understood as 10cm and 99mm and then snmpget/snmpwalk utility will do such conversions automatically? I tried to find such SNMP objects, but did not find any.


thanks,
Martin
