Bug ID 743233: Default engineID may have different lengths

Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:

Fixed In:

Opened: Sep 07, 2018

Severity: 2-Critical


The initial engineIDType on an unconfigured system is NETSNMP_RND. If the snmpd configuration file is read and there is no stored engine ID then one is generated based on current system time (and some other bits) to produce a random engineID. When randomly generated engineID changed length in release 14.0.0 of the BIG-IP to include some trailing zeros.


This can be confusing because the alert daemon and the snmp agent both issue traps and the alert daemon traps did not include the trailing zeros.


Use of unconfigured engineID on a clean install with version 14.0.0 or later. Note the engineIDType of NETSNMP_RND cannot be user configured.


There is no workaround.

Fix Information

The bug has been fixed and the trailing zeros are no longer included in the randomly generated engine ID.
