Werk #11752: Management board: SNMP bulk walk can now be configured

Component Core & setup
Title Management board: SNMP bulk walk can now be configured
Date Dec 7, 2020
Checkmk Edition Checkmk Raw (CRE)
Checkmk Version 2.0.0b2 2.1.0b1
Level Trivial Change
Class Bug Fix
Compatibility Compatible - no manual interaction needed

SNMP Management boards were previously contacted with different SNMP settings. SNMP management boards on non-SNMP hosts always used SNMPv1 (no bulk walk) while SNMP management boards of hosts that are also monitored with SNMP, inherited the bulk walk option from the host.

With Checkmk 2.0 it is now possible to explicitly configure this setting using the ruleset "Management board SNMP using bulk walk (enforces SNMP v2c)".

Sites created with Checkmk 2.0 or newer will automatically use SNMPv2 and bulk walks for all SNMP management boards. For compatibility reasons the behaviour of existing sites is kept as initially described. However, in case your devices support SNMPv2 and bulk walks, it is highly recommended to use it, for performance reasons. In case you want to change to SNMPv2, you can create a rule without condition in the ruleset "Management board SNMP using bulk walk (enforces SNMP v2c)" to switch the default to SNMPv2 and bulk walks.
