ROS version in snmp

Cyclone · Tue Jan 27, 2009 3:26 pm

After some extensive investigation I couldn't find the RouterOS version anywhere using snmp. On normal linux machines the kernel version info is normaly stored in sysDescr but for ROS it only contains router. How about adding the RouterOS version aswell as maybe the RouterBoard type to this description? Looking for RouterOS version to monitor rb ROS versions on highsites on a site.

This is what I gather and how from my mts.

do an SNMP-walk on your RouterOS device, and you will find the OID for the Version. Just saw it yesterday, but can't tell you the oid right now ..

I did, I rejected known OID's and ...

SNMPv2-MIB::sysDescr.0 = STRING: router
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.14988.1
SNMPv2-MIB::sysServices.0 = INTEGER: 78
IP-MIB::ipForwarding.0 = INTEGER: forwarding(1)
IP-MIB::ipDefaultTTL.0 = INTEGER: 255
SNMPv2-SMI::mib-2.17.2.1.0 = INTEGER: 3

However I do not see somewhere "= 3.17" or ("= 3" + "= 17")

If you want, I may attach my real snmpwalk.txt but its quite huge because of 800 routes.

maybe I don't understand this thing, but Dude SNMP-walk gives me:

iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrLicense.mtxrLicVersion.0
1.3.6.1.4.1.14988.1.1.4.4.0 = 3.20

Edit: maybe it's related to the fact that mine is a routerboard? I will look into this

My snmpwalk was from RB433ah

Edit:

you are right

# snmpwalk -v 1 -c public 10.86.89.129 1.3.6.1.4.1.14988.1.1.4.4.0
SNMPv2-SMI::enterprises.14988.1.1.4.4.0 = STRING: "3.17"

but because of an unknown reason, when I do snmpwalk, it does not return 1.3.6.1.4.1.14988.*

it just shows

SNMPv2-SMI::mib-2.9999.1.1.1.1.0 = STRING: "MikroTik DHCP server"
SNMPv2-SMI::mib-2.9999.1.1.1.2.0 = OID: SNMPv2-SMI::enterprises.14988.1
SNMPv2-SMI::mib-2.9999.1.1.6.4.1.1.11 = IpAddress: 10.86.89.158
SNMPv2-SMI::mib-2.9999.1.1.6.4.1.4.11 = INTEGER: 2
SNMPv2-SMI::mib-2.9999.1.1.6.4.1.5.11 = Gauge32: 217399
SNMPv2-SMI::mib-2.9999.1.1.6.4.1.7.11 = INTEGER: 3
SNMPv2-SMI::mib-2.9999.1.1.6.4.1.8.11 = Hex-STRING: 00 1F C6 2B E0 2B

Seems to me that Mikrotik may need to release a MIB (dictionary) file one of these days....

There are many thinks to be fixed and a lot to be created, but this, I think has totally really low priority. I would appreciate to have a better SNMP GUI than a MIB Dictionary. Anyway... lets see what 3.20 has.

True. In this specific case however, with your OIDs not 'resolving' - a MIB will solve this 100%. Seeing it is working in TheDude, I would bet that Dude actually already has a MIB that it is using.
