Opened: Sep 18, 2017
Severity: 3-Major

Symptoms

SNMP v1 does not support counter 64 variable types. The F5 MIB counters use this type so when walking the F5 MIBs you should use SNMP v2 or v3. In BIG-IP version 11.x the SNMP daemon did not report counter 64 variables in a mib walk but the walk continued. In BIG-IP version 12.x and forward the SNMP support for standard MIBs and view based access changed the behavoir such that the SNMP v1 mib walk gets a No Such Name error when it encounters a 64 bit variable and that terminates the walk.

Impact

The walk will stop with No Such Name when it encounters a Counter 64 variable.

Conditions

Using SNMP v1 to walk the F5 MIB.

Workaround

Use SNMP v2 or v3 to walk the MIBs.

Fix Information

None
