0.8.6.d missing hardware address/status/type in data query

Hi,

the interface query is missing some results that I can get with a snmpwalk on the command line.

[...]

+ Found type = '3' [snmp query].

### command line: ###

$ snmpwalk -Ov -v1 -c $community $switch ifOperStatus
INTEGER: up(1)
INTEGER: up(1)
INTEGER: up(1)
INTEGER: up(1)

$ snmpwalk -Ov -v1 -c $community $switch ifType
INTEGER: ethernetCsmacd(6)
INTEGER: ethernetCsmacd(6)
INTEGER: ethernetCsmacd(6)
INTEGER: ethernetCsmacd(6)

$ snmpwalk -Ov -v1 -c $community $switch ifHwAddr
ifHwAddr: Unknown Object Identifier (Sub-id not found: (top) -> ifHwAddr)

but this

$ snmpwalk -Ov -v1 -c $community $switch .1.3.6.1.2.1.2.2.1.6
STRING: 0

fd:84:bd:80
STRING: 0

fd:84:bd:81
STRING: 0:d:65:4:da:94
STRING: 0:d:65:4:da:95

works!

Any idea why the HW address is missing completely and the numeric values of some fields are not translated?

Contact your hardware vendor and ask them the same thing. If it's Windows, you should be seeing it.

TheWitness

ps. You might want to walk by hand and see if it's just missing:

Code: Select all

snmpwalk -c <your_community> -v <your_version> <hostname>

Hi

I have a rather similar problem : with Cacti 0.8.6d, "up" and "down" status are replaced by 1 and 2, and hardware addresses are missing :

- Cacti 0.8.6c

- Cacti 0.8.6d

This host is running Net-SNMP 5.2.1, and snmpwalk returns all the values :

Code: Select all

$ snmpwalk -v 1 -c public 10.50.80.10 .iso.org.dod.internet.mgmt.mib-2.interfaces | egrep "PhysAddress|OperStatus|Type"
IF-MIB::ifType.1 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.2 = INTEGER: softwareLoopback(24)
IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifPhysAddress.1 = STRING: 0:b0:d0:15:76:ce
IF-MIB::ifPhysAddress.2 = STRING:
IF-MIB::ifPhysAddress.3 = STRING: 0:10:b5:7:51:76
IF-MIB::ifOperStatus.1 = INTEGER: up(1)
IF-MIB::ifOperStatus.2 = INTEGER: up(1)
IF-MIB::ifOperStatus.3 = INTEGER: down(2)

Are you using php_snmp? Please run "php -m" for me and post.

Hi Larry

yes, I'm using php-snmp (I can see "PHP SNMP Support: yes" using about.php) :

Code: Select all

$ php -m | grep snmp
snmp

Can you rollback php support and see if the problem goes away? There are known problems with that build.

TheWitness

Can I do that by modifying

Code: Select all

$config["php_snmp_support"] = no;

in include/config.php ? Are there any "side effects" ?

Thanks for your support.

Hmm. Give it a shot, but it will slow down recaches for snmpv1 devices.

Hi,

I just updated some packages with yum (fedora core 3), now I get:

php -m | grep snmp
PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php4/snmp.so' - /usr/lib/php4/snmp.so: undefined symbol: usmAES192PrivProtocol in Unknown on line 0

php-snmp-4.3.11-2.4
net-snmp-devel-5.2.1-10.FC3
net-snmp-5.2.1-10.FC3
net-snmp-utils-5.2.1-10.FC3
net-snmp-libs-5.2.1-10.FC3

I think the update a few minutes age made the whole thing worse...

In config.php I have
$config["php_snmp_support"] = false;

At least I could solve this problem. The latest net-snmp fedora update broke php-snmp.

https://bugzilla.redhat.com/bugzilla/sh ... ?id=155975

But this shouldn't be the problem with cacti, because I have set
$config["php_snmp_support"] = false;

to false...

I'm also getting 1 and 2 for interface status instead of Up and Down. I'm running PHP 4.3.10 and net-snmp 5.0.9 on SENTINIX. I just recently upgraded from PHP 4.3.4 and the problem existed there too. Did you find a fix for this pirx?

Post by **TheWitness** » Mon May 02, 2005 5:45 pm

Possibly an issues with mibs. You should attempt to walk the OID's using the snmpwalk command from a shell script and verify your output.

Do you need more snmpwalk information than I added to the first post?

### command line: ###

$ snmpwalk -Ov -v1 -c $community $switch ifOperStatus
INTEGER: up(1)
INTEGER: up(1)
INTEGER: up(1)
INTEGER: up(1)

$ snmpwalk -Ov -v1 -c $community $switch ifType
INTEGER: ethernetCsmacd(6)
INTEGER: ethernetCsmacd(6)

INTEGER: ethernetCsmacd(6)

$ snmpwalk -Ov -v1 -c $community $switch ifHwAddr
ifHwAddr: Unknown Object Identifier (Sub-id not found: (top) -> ifHwAddr)

but this

$ snmpwalk -Ov -v1 -c $community $switch .1.3.6.1.2.1.2.2.1.6
STRING: 0fd:84:bd:80
STRING: 0fd:84:bd:81
STRING: 0:d:65:4:da:94
STRING: 0:d:65:4:da:95

works!

Are you using cactid as your poller. If so, have you set the MIBS=ALL variable. If so, remote it and reboot. Then, manually recache your hosts.

Yes, I use cactid as poller, MIBS=ALL is not set. With "manually recache you hosts", do you mean Console->System Utilities->Clear Poller Cache?
