New Router - SNMP Failing

[DFord]

I have just replaced a router in my network and now Cacti is not collecting data. Debug as follows from last poller cycle:

Code: Select all

Can anyone tell me what I did wrong? I tried re-indexing the host an I also tried creating a new host but all to no avail...

Does cacti see the basic snmp information for the new router?

Does snmpwalk from your cacti server against the new router return any data? Try using the OIDs cacti was unsucessfully able to poll.

I get the following from an SNMP walk:

Code: Select all

.1.3.6.1.2.1.2.2.1.16.11 No more variables left in this MIB View (It is past the end of the MIB tree)

.1.3.6.1.4.1.9.2.1.58.0 No more variables left in this MIB View (It is past the end of the MIB tree)

.1.3.6.1.2.1.2.2.1.10.11 No more variables left in this MIB View (It is past the end of the MIB tree)

And still getting this in the log:

Code: Select all

This is the log file from the last debug polling cycle.

[BSOD2600]

What I mean by basic snmp information is when you click on the r1wygor.weyerhaeuser.com device in cacti, in the top left corner do you see the uptime / OS info or 'snmp error'?

Until you're able to successfully snmpwalk the device, don't expect cacti to be able to gather any snmp information. Try: "snmpwalk -v 1 -c public r1wygor.weyerhaeuser.com.au system"

**Delay due to illness**

When I try an SNMP Walk, I get the following:

Code: Select all

C:\>snmpwalk -v 1 -c public r1wygor.weyerhaeuser.com.au system
Cannot find module (NOTIFICATION-LOG-MIB): At line 1 in (none)
Cannot find module (NET-SNMP-AGENT-MIB): At line 1 in (none)
Cannot find module (DISMAN-EVENT-MIB): At line 1 in (none)
End of MIB

C:\>

Cacti does not see the basic SNMP Information. In the top left of the device information page, I have the following:

Code: Select all

SNMP Information
System: No Such Object available on this agent
Uptime: No Such Object available on this agent
Hostname: No Such Object available on this agent
Location: No Such Object available on this agent
Contact: No Such Object available on this agent

The router has the same base configuration as the previous Cisco 1603 (The New one is a Cisco 1821 running IOS 12.4)

I have checked the community strings (and I substituted the correct one in the SNMP Walk that I tried).

I am guessing that there is something simple I have missed...?

[BSOD2600]

Sounds like snmp is not working on the router (at least from the Cacti server). Until you fix that, cacti won't work...

[DFord]

Finally sorted it out, I think.

The SNMP Community name was case-sensitive! When I changed it to all CAPS (as it is in the Router), everything worked.

Thanks for all your help.
