SNMP Get Failing - No user ports reported

[scruboy01]

I am seeing no user ports up and no active MACs. I think it is centered around this error message:

Code: Select all

CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'<hostname>', and OID:'.1.3.6.1.2.1.17.1.2.0'

snmpget from the command line completes successfully.

Running a php snmp2_get from the command line completes successfully.

Running php in interactive mode and going through the cacti_snmp_get function completes successfully (passing snmp version 2).

Any suggestions as to why this is failing in the script but not when run manually?

It's likely attempting a bulkwalk using the snmp binaries and failing due to a timeout. Increase the timeout of this device. If that does not work, you may have to simply use snmpv1. Who is the manufacturer, and what is the model.

Upped the timeout from 1000 to 1500. Then switched to v1. No luck. All devices are Cisco 6500s with a sup720.

They should report fine as snmpv2. Without more information, I'll have problems with this one. How about a screen shot of the MacTrack devices page? If it's a sup720 and it's really busy, you may have to due a timeout of 4 seconds.

See attached print screen.

These things are not tasked at all. CPU is around 3% for most of them. This is a new network so there is not much traffic right now. The command lines snmpget comes back immediately.

Any thing else I can provide? Appreciate the help!

Please run the mactrack_scanner.php on one of the devices in debug mode and attach the output.

Any chance to look at this?

Thanks

Hmm. We need another higher level of Debug. If you do the following:

1) Edit include/global.php and where the check happens for snmp, set the values to FALSE;
2) Rerun the scanner from the CLI and let me know if it works fine now.

This was the only line I could find in global.php referring to SNMP:

Code: Select all

$config["php_snmp_support"] = function_exists("snmpget");

Changed to:

Code: Select all

$config["php_snmp_support"] = 0;

It's almost as if you don't have the bridge mib enabled or the port type is not Ethernet. Looks like we need a higher debug level. Interesting as this method has worked for over 5 years. Something must be different on your equipment. What types of ports are these? Send me a walk of the ifInterfaces table.

Attached is a walk of .1.3.6.1.2.1.2.2 for a l3 switch and a l2 switch.

Have you had a chance to look at this yet?

Thanks,
