Doc Text:
Before this release, length of OID parameter of "sysObjectID" snmpd.conf config file option was not correctly stored in snmpd, which resulted in SNMPv2-MIB::sysObjectID being truncated if the OID had more than 10 components. In this update, handling of the length of the OID is fixed and SNMPv2-MIB::sysObjectID is returned correctly.

Description dcardimi 2012-02-02 17:03:37 UTC
Description of problem:
sysObjectID can be configured in /etc/snmp/snmpd.conf.  However, if you set it to an OID with a length greater than 10 (the default value's length), it only reports the first 10 digits.  For example, the default value is ".1.3.6.1.4.1.8072.3.2.10".  If you change it to ".1.3.6.1.4.1.9.8.7.6.5.4.3", the agent will only report ".1.3.6.1.4.1.9.8.7.6".

Version-Release number of selected component (if applicable):
net-snmp-5.5-37.el6_2.1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Edit /etc/snmp/snmpd.conf, and add a line to specify the sysObjectID - something like "sysObjectID .1.3.6.1.4.1.9.8.7.6.5.4.3"
2. Restart the agent
3. Query the sysObjectId
  
Actual results:
The agent will return the specified OID truncated to ".1.3.6.1.4.1.9.8.7.6"

Expected results:
The agent should return the whole OID as specified in the config file.
