SmiManager

✓ import snmpsim

✗ from snmpsim import SmiManager

Starts the SNMP simulator with a local agent endpoint and data directory.

snmpsimd --version

Debug

Known issues

breakingsnmpsim 1.0+ removed support for Python 2 and older Python 3 versions. Requires Python 3.10+.

fix

Upgrade Python to 3.10+ and use snmpsim >=1.0.0.

affects: <=0.4.x

deprecatedThe `snmpsimd` command-line script has been deprecated. Use `snmpsim-command-responder` instead.

fix

Replace `snmpsimd` with `snmpsim-command-responder` in scripts and documentation.

affects: >=1.0.0

gotchaData directory must follow a specific structure (e.g., subdirectories for each simulated agent) or the simulator may silently fail.

fix

Ensure each agent has its own folder with files like 'snmp_v1.snmprec', 'snmp_v2c.snmprec', etc.

affects: all
