Some Cisco OIDs Not Working on Router

[perric]

Hello,

I have Nagios XI 2012R2.9. Using the check_snmp from the GUI, i am able to test and get one OID to respond, but not another on the same Cisco router:

-o .1.3.6.1.2.1.33.1.2.1.0 (system uptime) --> OUTPUT: SNMP OK - Timeticks: (23531231) 2 days, 17:21:52.31 |

-o .1.3.6.1.2.1.10.20.1.3.4.1.2 (isdnLapdOperStatus) ---> OUTPUT: SNMP problem - No data received from host

I am converting my SNMP monitoring from PRTG to Nagios and the OIDs work from PRTG on this same device, when using the same MIB (ISDN-MIB-V1SMI). I have checked the device and there are no commands specific to the PRTG server, so it looks like something I am missing in Naios.

Does that second OID show up in a snmpwalk or is it otherwise directly queryable from the command line?

Hello,

snmpwalk output...

I see these errors, but I am not sure how to resolve.

Looks like there may be an issue with the mib.
Could you post a copy of the mib in code wraps, attached, or as a link?

[perric]

Sure... Here is a link to the MIB contents (at bottom of page).

I think the following lines need to be something like:

Code: Select all

Line 30:
::= { coldStart 0 }

Line 40:
::= { linkDown 2 }

Line 50:
::= { linkUp 3 }

Line 64:
::= { authenticationFailure 4 }

Line 74:
::= { egpNeighborLoss 4 }

Line 86:
::= { reload 0 }

Line 98:
::= { tcpConnectionClose 1 }

Thanks.

I will try this fix, when I can resolve another issue removing old MIB files from Nagios. I have submitted this under the title of "Cannot Remove MIB" in this same forum.

Detail: When I try to delete and re-add a MIB file, it seems that a "processed" or "converted" MIB is still in place somewhere else, even though I have deleted the MIB file and placed a new one into /usr/share/snmp/mib folder. See addmib message below:

[root@cawlk mibs]# addmib /usr/share/snmp/mibs/CISCOTRAP-MIB.my
This file looks like it has been added already! Exiting.

Since you already have responses in that thread, let's keep the fix over there and return here once that's resolved.

[perric]

Still cannot remove old MIB and re-add this MIB to test... hoping to resolve the issue soon.

Ok. Progress. I remove a MIB that seemed to be causing a problem and I now get this.

[root@cawlk mibs]# snmpwalk -mALL -v1 -cXXXXX 192.168.83.75 1.3.6.1.2.1.10.20.1.3.4.1.2
ISDN-MIB::isdnLapdOperStatus.43 = INTEGER: inactive(1)
ISDN-MIB::isdnLapdOperStatus.1314 = INTEGER: l2Active(3)

My check_snmp still comes back with "No data received from the host".

[root@cawlk mibs]# check_snmp -C cXXXXX -H 192.168.83.75 -o 1.3.6.1.2.1.10.20.1.3.4.1.2
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m '' -v 1 [authpriv] 192.168.83.75:161 1.3.6.1.2.1.10.20.1.3.4.1.2
[root@cawlk mibs]#

Do I need to edit the /etc/snmp/snmptt.conf and tweak the values?
