SNMP Cisco 2811

[Frasco]

Hello,

I've trying to add to my Cacti my Cisco 2811 Router. I have talked with the ISP (he is the owned of the router) and they have configured the SNMP.

The problem is that when I try to add the Device, the Cacti says me "SNMP Error" and I can't do anything. I've tested with the GetIf program and it says me "SysInfo variables OK", but it doesn't show me the Routing Table, The CPU Information... It only says me what is the IP of the Router.

What should I do? Is any problem of the Cisco configuration or what?

Thanks!
Best regards!

[Frasco]

I've talked with my ISP and he says me that my Cisco Router is SNMP v1

I've tried again on the cacti and the log says:

"CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'192.168.0.10', and OID:'.1.3.6.1.2.1.1.1.0' "

I've increased the SNMP timeout to 1000000 but the problem persists.

Any idea?

[BSOD2600]

If GetIF and/or net-snmp snmpwalk do not work, then something is not properly configured with the router.

This is a non-windows specific issue, moving.

I've tried the command snmpwalk -v1 -c public 192.168.0.10 into CMD and I get this:

It means that my router is answering me, is not? Should I try another thing?
Thanks!

Hello, I've tried the next command and I obtain the next error:

Code: Select all

C:\>snmpget -v 1 -c public 192
.168.0.10 .1.3.6.1.2.1.1.1.0
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-MIB::sysDescr.0

I don't know if I'm writing good the command or not.

Thanks!

[gandalf]

Cacti tries to detect availability based on this OID. Most systems respond to that OID. Unfortunately, your device doesn't. It may happen, that the configuration prohibits access to that. Again, talk to your ISP regarding this fact.

[Frasco]

Hello, I have phoned to my ISP and they have told me that everything's ok. They have told me too that, if we see the comand of the previous post, it says "Failed object: SNMPv2-MIB::sysDescr.0" and they don't know what means the v2 into this line, because the CISCO operates on v1.

Can we do anything? They say me that all is ready and they can receive data succesfully.

Thanks!

I've tried the command snmpwalk -v1 -c public 192.168.0.10 into CMD and I get this:

C:\>snmpwalk -v1 -c public 192.168.0.10
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (522070053) 60 days, 10:11:40.5
3
SNMPv2-MIB::sysName.0 = STRING: madrid2
...

But this WAS working!
In fact, SNMPv2-MIB is (afaik), optional.
As a workaround, you may want to edit host.php and change the failing OID to .1.3.6.1.2.1.1.5.0 (which related to sysName)

Ok. I have changed the OID into the host.php and now I can see the name of the system, uptime, hostname... into the device section. But I can't create graphs for the host.

I have the data query "SNMP - Interface stadistics" and in debug mode I can see the next log:

Code: Select all

And, if I go to the Cacti Log I can see:

Code: Select all

What must I do??

Thank you very much again, Gandalf.

It seems, that ".1.3.6.1.2.1.2.2.1.1" does not return any data. Please walk against that OID using the option "-On" to get numeric OIDs. I fear, that this very OID is still blocked

Hello Gandalf, I'm sorry but I can't obtain data because I don't know surely the command I have to put. I've try the next commands:

Code: Select all

C:\>snmpwalk -v1 -c public 192.168.0.10 -On .1.3.6.1.2.1.2.2.1.
-On:  (Sub-id not found: (top) -> -On)

C:\>snmpwalk -v1 -c public 192.168.0.10 -On
-On:  (Sub-id not found: (top) -> -On)

C:\>snmpwalk -v1 -c public .1.3.6.1.2.1.2.2.1.
snmpwalk: Unknown host (.1.3.6.1.2.1.2.2.1.) (No such file or directory)

C:\>snmpwalk -v1 -c public 192.168.0.10 .1.3.6.1.2.1.2.2.1.

C:\>snmpwalk -v1 -c public 192.168.0.10 .1.3.6.1.2.1.2.2.1.1 -On

Are they ok?

Thanks

snmpwalk -v1 -c public -O n 192.168.0.10 .1.3.6.1.2.1.2.2.1

resource/snmp_queries/interface.xml indeed requires that <oid_index>.1.3.6.1.2.1.2.2.1.1</oid_index>is available.
But your walk does not show any data for the interface index.
This looks like a root cause to your problem.
