Bug #81415 [NEW]: Missing some SNMP::walk() values
From: miloslav dot hula at gmail dot com
Operating system: Linux
PHP version: 8.0.10
Package: SNMP related
Bug Type: Bug
Bug description:Missing some SNMP::walk() values
Description:
------------
When walking through access points table on Cisco WLC 5508 wifi
controller, not all records are in resulting array when met following
conditions:
1) corresponding MIBs has to be loaded - so OID-to-name translation is
working
If not, returning keys are always in numeric OID format and result is
comlete.
2) oid_output_format has to be set to one of: SNMP_OID_OUTPUT_FULL,
SNMP_OID_OUTPUT_MODULE, SNMP_OID_OUTPUT_SUFFIX, SNMP_OID_OUTPUT_UCD
With SNMP_OID_OUTPUT_NUMERIC everything works.
3) SNMP::walk() parameter 'suffixAsKey' has to be false (default)
If not, returning array keys are numeric OIDs and result is complete.
This bug is probably related to https://bugs.php.net/bug.php?id=76356
It seems that "named" OIDs with "binary suffix" are translated to
duplicit array keys. For examle from list below:
16.189.24.198.140.96 <-- missing
220.165.244.156.215.96 <-- missing
236.225.169.240.152.96 AIRESPACE-WIRELESS-MIB::bsnAPName.'.....`'
Every OID part outside the <32; 126> interval (readble ASCII) is
translated to '.' (dot char) so resulting suffix is '.....`' which is
duplicit in result.
Following list shows which access points are missing:
