When processing SNMP data, space delimited hex strings do not always convert into MAC addresses

[PonomarenkoVladimir]

Describe the bug
Error processing hex-lines (MAC-address)

To Reproduce
Have a Script Query XML File
The output format of the field “spMeshLinkNodeId”: hex

Steps

1. Select "Management" -> "Devices" -> My Device
2. Select "Associated Data Queries"
3. Select "Verbose Query"
   

Result: : no print MAC-address of the equipment (field ”spMeshLinkNodeId”)

Expected behavior
I fixed the error in the file ./lib/snmp.php
Result:

Because I do not know the logic of the program, the text of the correction is not attached.

Please upload your updated lib/snmp.php. Thanks!!

[cigamit]

I have attempted to validate this one using core Cacti 1.2.4/1.2.5 and can not. Can you please also update to develop or 1.2.4 after you upload your modified lib/snmp.php file?

[cigamit]

Oh, I was not able to validate using the ifInterfaces HwAddress walk. You might also want to upload the output of this command:

snmpwalk -c yourcommunity -v2c -Ox youhostname theOIDinQuestion

Also, what happens when you change type from 'get' to 'walk'?

[PonomarenkoVladimir]

My updated lib/snmp.php file for version Cacti 1.2.4:
snmp.php.tar.gz
My changes are marked "**********"

Command output:
snmpwalk -c public -v2c -Ox 172.17.2.186 .1.3.6.1.4.1.15319.2.2.1.4.0
iso.3.6.1.4.1.15319.2.2.1.4.0 = Hex-STRING: 00 0A DB 08 9F BF

Also, what happens when you change type from 'get' to 'walk'?
Result:

The result has not changed.

[cigamit]

Yea, those changes looked mostly good. Committing momentarily. Then I would like you to test it.

[cigamit]

Okay, it's uploaded. Please test.
